Room Preparation

During the design of the data center, consider ease of entry for the equipment, floor loading factors, and

accessibility to piping and wiring.

Seal the room with a vapor barrier to minimize moisture infiltration. (Polyethylene film is recommended

for ceiling and wall applications.) Apply rubber- or plastic-based paints to concrete walls and floors.

Insulate the room to minimize the influence of exterior heat loads. Use the minimum required amount of

fresh air for make up to comply with local and national codes and regulations. Fresh air imposes extreme

load variation on the cooling equipment from summer to winter and causes increased operating costs.

The equipment is designed as a sensible cooling air conditioning unit for in-row use in data centers. The

equipment does not have humidification or dehumidification control. Room humidity must be within

acceptable operating conditions before starting equipment. If operated in spaces where the humidity

is in the unacceptable operating conditions section of the Operating Guidelines chart (see the InRow RC

Operation and Maintenance manual) the equipment condenses excess water vapor from the air. This will

exceed the pumping capacity of the condensate pump, causing the equipment to send an alarm and shut

down to avoid overflowing the condensate pan. The condensate pump runs until the fluid level in the pan

is reduced, and the alarm is automatically reset. The equipment self-regulates in this manner until normal

operating conditions are present.

Note: The InRow RC is not intended to be used in an occupied office environment, due to

potentially high noise levels during peak loads. Install the InRow RC in a computer room

where people are normally present only for maintenance.

Incoming power supply requirements

See the electrical rating label on the equipment to determine the maximum possible current draw of the

equipment. Provide either a single outlet circuit or a Power Distribution Unit (PDU) with sufficient

capacity to handle all loads. Do not plug two InRow RC units into the same branch circuit or PDU.

The equipment must be grounded. Electrical service must conform to national and local electrical codes

and regulations.

Piping Diagrams

With cooling distribution unit (CDU)

Note: Install isolation valves and particulate strainers with 20 mesh stainless steel screen

(opening size = 865 micron) in the supply line between the chiller and the CDU. If the system

is to be set up as an isolated loop - a chiller and pipe layout, dedicated only to supplying RC

units and no other equipment - the strainer may be placed in the piping circuit before the pump.

Thoroughly flush the system to remove all debris and process chemicals.

Note: Top or bottom entry can be chosen individually for each type of connection, i.e. power,

condensate drain, humidifier water supply, chilled water supply and chilled water return. Top

piping configurations will have the same valves and strainers as bottom piping configurations.

“Piping Diagrams,”

beginning on page 8.

Layout and piping

considerations.

Fluid pipes are not

allowed directly

above electrical

equipment. All

piping must be

installed above the

aisles as shown. If

any piping makes a

turn, or must be

routed over electrical

equipment, there

must be a drip tray

under the pipe that

will protect the

equipment from

condensation and

leaks. All piping

must be kept separate

from any electrical

runs or wiring.

Insulation. Insulate

water lines to protect

personnel and to minimize condensation.

Note: Using either tape or glue, completely seal the insulation boots covering the unused

supply and return connections.

insulated wires. The low-voltage connections must have 300-V minimum insulation.

Note: Single phase service is required. Electrical service must conform to national and local

electrical codes. The InRow RC is grounded through the power cord.

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Turn off all power supplying this equipment before working on the equipment.

Power connections

Power cords may be routed through the top of the equipment (standard) or through the bottom (optional).

Top wiring configuration

(standard).

1. Route power cords

through the

equipment to the top

power cord access,

as shown.

2. Push the power cords

through the hole at

the top power cord

entrance.

3. Secure the plate to

the underside of the

equipment top with

four Phillips screws

(provided).

4. Secure the power

cords at appropriate

locations inside the

equipment using the

provided tie wraps.

Bottom wiring configuration (optional).

1. Remove the blank plate from the bottom power cord entrance. Save the plate and the four Torx

screws.

2. Route the power cords through the equipment to the bottom power cord access, as shown.

3. Feed the power cords through the hole at the bottom power cord entrance and secure the plate to

the bottom of the equipment with the four Torx screws you saved in step 1.

4. Secure the blank plate to the top power entrance with four Phillips screws (provided).

5. Secure the power cords at appropriate locations inside the equipment using the provided wire

ties.

Feeds A and B. The equipment is capable of receiving power through one of two separate feeds, feed

A or feed B. Use the display interface to configure the unit to receive power through feed A, feed B, or

both). If connected, feed B is the primary power input to the equipment by default; feed A is the backup

power input. The equipment receives power through feed B regardless of whether feed A is receiving

power. If power is removed from feed B, feed A takes over and supplies power to the equipment (if feed

A is connected). Connect the feed A and feed B cables to individual, breaker-controlled branch circuits

or to PDUs backed by separate Uninterruptible Power Supplies (UPS).

Note: Feed A and feed B must not use the same branch circuit, PDU, or UPS.

For more information on configuring power input feeds, see the InRow RC Operation and

Maintenance manual.

Form C alarm contacts and shutdown input

A relay internal to the user interface is typically controlled by a user-defined alarm (malfunctioning fans,

for example). Before an alarm is detected, the voltage on the COM terminal is routed to the NC terminal.

When the alarm is activated, the relay is energized, causing the voltage on the COM terminal to be

routed to the NO terminal. The NO and NC terminals may be connected to remote indicator lights, a

warning buzzer, or another device to alert an operator to the presence of an alarm condition.

A remote disconnect switch may be connected to the shutdown inputs.

Leak detector port

Rope water detector (AP9325). Up to four optional rope water

detectors can be installed in series. The rope water detector

connects to the RJ-45 leak detector port located at the top of the

interface box.

See the “Rope Water Detector” installation sheet

(supplied with the kit) for installation and setup information.

Temperature sensor

The remote temperature sensor monitors the room temperature,

monitoring the environment surrounding the cooling equipment to

ensure that the conditioned air is cooling the area.

Note: The remote temperature

sensor comes coiled inside the

equipment as shown, and must

be mounted as follows, or the

equipment will not operate

properly.

Install the temperature sensor.

1. Route the rack temperature sensor through the hole in

either the top or bottom of the unit.

2. Route the sensor through either the top or the bottom

of the adjacent server rack.

3. Secure the temperature sensor cable to the front door

of the adjacent server rack at multiple locations using

the provided wire clips as shown. See “Installation

kit” on page 3.

The sensors must be installed where lack of sufficient

cooling air is most likely. The optimum position of the

rack temperature sensors will vary from installation to

installation, but should be located in the airflow to

allow accurate readings.

Servers most likely to have insufficient air or inadequately cooled air due to the recirculation of

hot air from the hot aisle include:

a. Servers positioned at the top of a rack.

b. Servers positioned at any height in the last rack at an open end of a row.

c. Servers positioned behind flow-impairing obstacles such as building elements.

d. Servers positioned in a bank of high-density racks.

e. Servers positioned next to racks with Air Removal Units (ARU).

f. Servers positioned very far from the equipment.

g. Servers positioned very close to the equipment.
