LIEBERT DS MODEL NUMBER

Not all combinations of options are available on all units.

Digital Scroll Compressors

• Not available on 077 and 105 models

• Not compatible with SCR reheat because digital scroll provides variable capacity control

EC Fans, Direct-Drive

• Not available on upflow (VS) configuration

• Liebert Econ-O-Coil™ not available on 028, 035, 042 models with 208/230V

Steam Generating Canister Humidifier

• Not available on EC fan configurations

575 Volt Option Limitations

• Digital scroll compressors available only on 053, 070 models

GLYCOOL Liebert Economizer Models

• 105 model requires semi-hermetic compressors only, so as to prevent potential coil freezing

Turning Vanes

1.0 COOLING CONFIGURATIONS

NOTE

All field-installed piping must comply with applicable local, state and federal codes.

AIR-COOLED

Air-cooled unit piping is spun closed from the

factory and contains a nitrogen holding charge.

Each installation requires field-supplied

refrigerant and piping to a condenser.

GLYCOL-COOLED

Glycol-cooled units are factory-charged and

tested. Field-supplied and field-installed piping is

required from the unit to the drycooler and pump

package.

WATER-COOLED

Water-cooled units are factory-charged and

tested. Field-supplied and field-installed

water piping is required from the unit to the

cooling tower.

GLYCOOL-INTEGRATED FLUID ECONOMIZER

GLYCOOL units are factory-charged and tested. Field-supplied

and field-installed piping is required from the unit to the

drycooler and pump package. An additional Liebert Economizer

coil is included for use when fluid temperatures are sufficiently

low (below room temperature). Economizer cooling is provided

by circulating cold glycol through this second coil, reducing or

eliminating compressor operation.

DUAL-COOL

This system has all of the features of a compressorized

system, but adds a second cooling coil that is connected

to a source of chilled water. Cooling is provided by

circulating chilled water, when available, through this

second coil and reducing compressor operation.

Liebert units.

7. Remote unit shutdown—Replace existing jumper between Terminals 37 & 38 with

field-supplied normally closed switch having a minimum 75VA, 24VAC rating. Use field-supplied

Class 1 wiring.

8. Customer alarm inputs—Terminals for field-supplied, normally open contacts, having a

minimum 75VA, 24VAC rating, between Terminals 24 & 50, 51, 55 & 56. Use field-supplied

Class 1 wiring. Terminal availability varies by unit options.

9. Common alarm—On any alarm, normally open dry contact is closed across Terminals 75 & 76

for remote indication. 1A, 24VAC maximum load. Use Class 1 field-supplied wiring.

10. Heat rejection interlock—On any call for compressor operation, normally open dry contact is

closed across Terminals 70 & 71 (Circuit 1), 230 (Circuit 2) to heat rejection equipment. 1A,

Liebert MC series condenser, remove jumper between Terminal 71 and Terminal 230. Three

wires must connect Terminals 70, 71 and 230 of the indoor unit to Terminals 70, 71 and 230 of the

Liebert MC series condenser.

11. Unit factory installed disconnect switch, Fuse Block and Main Fuses—Two types of

disconnect switches are available: Non-Locking and Locking. The Non-Locking Type consists of a

non-automatic molded case switch operational from the outside of the unit. Access to the

high-voltage electric panel compartment can be obtained with the switch in either the On or Off

position. The Locking Type is identical except access to the high-voltage electric panel

compartment can be obtained only with the switch in the Off position. Units with fused

disconnects are provided with a defeater button that allows access to the electrical panel when

power is On. The molded case switch disconnect models contain separate main fuses. Units with

fused disconnect have main fuses within the disconnect. Only fused disconnects are used on dual

disconnect options.

12. Secondary disconnect switch and earth ground

13. Three-phase electrical service—Terminals are on top of disconnect switch. Three-phase

service not by Emerson.

14. Smoke sensor alarm—Factory-wired dry contacts from smoke sensor are 91-common, 92-NO,

and 93-NC. Supervised contacts, 80 & 81, open on sensor trouble indication. This smoke sensor is

not intended to function as or replace any room smoke detection system that may be required by

local or national codes. 1A, 24VAC maximum load. Use field-supplied Class 1 wiring.

15. Reheat and humidifier lockout—Remote 24VAC required at Terminals 82 & 83 for lockout of

reheat and humidifier.

16. Condensate alarm (with condensate pump option)—On pump high water indication,

normally open dry contact is closed across Terminals 88 & 89 for remote indication. 1A, 24VAC

maximum load. Use field-supplied Class 1 wiring.

17. Remote humidifier—On any call for humidification, normally open dry contact is closed across

Terminals 11 & 12 to signal field-supplied remote humidifier. 1A, 24VAC maximum load. Use

Class 1 field-supplied wiring.

18. Auxiliary cool contact—On any call for Econ-O-coil operation, normally open dry contact is

closed across Terminals 72 & 73 on dual cool units only. 1A, 24VAC maximum load. Use

field-supplied Class 1 wiring.

3.4 OPTIONAL LOW-VOLTAGE TERMINAL PACKAGE CONNECTIONS

Source: DPN000807, Rev. 8

19. Remote unit shutdown—Two additional contact pairs available for unit shutdown (labeled as

37B & 38B, 37C and 38C). Replace jumpers with field-supplied, normally closed switch having a

minimum rating of 75VA, 24VAC. Use field-supplied Class 1 wiring.

20. Common alarm—On any alarm, two additional normally open dry contacts are closed across

Terminals 94 & 95 and 96 & 97 for remote indication. 1A, 24VAC maximum load. Use

field-supplied Class 1 wiring.

21. Main fan auxiliary switch—On closure of main fan contactor, normally open dry contact is

closed across Terminals 84 & 85 for remote indication. 1A, 24VAC maximum load. Use

field-supplied Class 1 wiring.

22. Liebert Liqui-tect™ shutdown and dry contact—On Liebert Liqui-tect activation, normally

open dry contact is closed across Terminals 58 & 59 for remote indication (Liebert Liqui-tect

sensor ordered separately). 1A, 24VAC maximum load. Use field-supplied Class 1 wiring.

Customer Piping and Wiring Connections

1. For primary connection locations see standard submittals DPN000803, DPN000804 or DPN000900.

A floor stand at least 9" high is recommended if primary connections locations are to be used.

2. If no floor stand is used and unit is placed directly on the floor, then do the following:

a) Use secondary connection locations (shown on standard floor planning submittals).

b) Order a condensate pump.

c) Field pipe condensate and humidier line (if ordered) to secondary connection point in

compressor section.

d) Or order additional SFA's to relocate connection locations

Customer Piping and Wiring Connections

1. For primary connection locations see standard submittals DPN000928,

DPN000929 or DPN000933.

A floor stand at least 9" high is recommended if primary connections locations are to be used.

2. If no floor stand is used and unit is placed directly on the floor, then do the following:

a) Use secondary connection locations (shown on standard floor planning submittals).

b) Order a condensate pump.

c) Field pipe condensate and humidier line (if ordered) to secondary connection point in

compressor section.

d) Or order additional SFA's to relocate connection locations

Customer Piping and Wiring Connections

1. For primary connection locations see standard submittals DPN001014 or DPN001015.

A floor stand at least 9" high is recommended if primary connections locations are to be used.

2. If no floor stand is used and unit is placed directly on the floor, then do the following:

a) Use secondary connection locations (shown on standard floor planning submittals).

b) Order a condensate pump.

c) Field pipe condensate and humidier line (if ordered) to secondary connection point in

compressor section.

d) Or order additional SFA's to relocate connection locations
