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.

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. 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. 28 InRow RC Installation na 1584 a Leak detector port Temperature sensor Remote temperature sensor na2271a 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. gen0744a 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. 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. Temperature sensor gen0767a Wire clip 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.
