1.Electric conduit knockouts on top and bottom of electric box. Knockout size 1-3/4" (44.5mm).

2.Three-phase connection. Electric service connection terminals when factory disconnect is NOT supplied.

3.Three-phase connection. Electric service connection terminals when factory disconnect switch is supplied.

4.Factory-installed disconnect switch. (Optional).

5.Three-phase electric service field-supplied.

6.Earth ground connection (50/60Hz). Connection terminal for field-supplied earth grounding wire.

7.Earth ground bar (50Hz only). Connection terminals with factory ground from each high voltage component for field supplied earth grounding wire.

8.Control and monitoring section of electric box.

9.Remote unit shutdown. Replace existing jumper between Terminals 37 + 38 with normally closed switch having a minimum 75VA, 24VAC rating. Use field-supplied Class 1 wiring. Two additional contact pairs available as an option (labeled as 37B & 38B, 37C & 38C). Replace existing jumper for appropriate pair as done for 37 & 38.

10.Special alarm connections. Field-supplied 24V Class 1 wiring for special alarm. Connection made by adding normally open contacts between terminals 24 + 50. Special alarm connections may be factory-wired or field-wired. See schematic for factory wired special alarms. For field-wired special alarms, use 24V Class 1 wiring to connect normally open contacts between Terminals 24 & 50, 24 & 51, 24 & 55, or 24 & 56.

11.SiteScan connection. Terminals 77 (-) and 78 (+) are for connection of a 2-wire, twisted pair, communication cable (available from Liebert or others) to optional Liebert SiteScan®.

12.Remote condensing unit connection. Field-supplied 24V Class 1 wiring to remote condensing unit Terminals 1, 2, 3, & 4 from (R2) relay (split system only).

13.Smoke detector alarm connections. Field-supplied 24V Class 1 wiring to remote alarm circuits. Factory-wired contacts from optional smoke detector are #91-comm., #92-NO, and #93-NC.

14.Common alarm connection. Field-supplied 24V. Class 1 wiring to common alarm Terminals 75 + 76 (and optional 94 + 95, and 96 + 97), which are factory-connected to common alarm relay (R3).
