AC Supply and Wiring for the Customer Status Contacts (30) TB1 (31) Normally Open Output (Status) (32) COM Output (Status) (33) Normally Closed Output (Status) (34) AC Input Phase A (35) AC Input Phase B (36) AC Input Phase C (37) TB2 (38) Location for Mounting the ConduitRefer to the section "Requirements for the Conduit" before installing the conduits for the wiring of the AC voltage.Note: Penetration of the wall of the cabinet requires a female threaded fitting on the end of the conduit. The following paragraphs detail the requirements for the wiring for the AC supply and the wiring installation of the Customer Status Contacts. Refer to Illustration 2.The wiring for the AC supply must meet the following specifications: Size ... 8 AWG Torque Value ... 4.97 N m (44 lb in) Composition of the Wire ... Copper Minimum Temperature Rating ... 75 °C (167.0000 °F)The wires that are used to connect the Generator Set Start Module to the UPS must comply with the following guidelines:
The wire must be run in a conduit.
The wire must comply with all national ordinances and local ordinances.Refer to Illustration 2 when performing the following steps.
Make sure that the ground wire is connected.
Connect the wire for the "a" phase of the incoming voltage to connector (34) that is located in the Generator Set Start Module.
Connect the input wire for the "b" phase of the incoming voltage to connector (35) on the Generator Set Start Module.
Connect the input wire for the "c" phase of the incoming voltage to connector (36) on the Generator Set Start Module.
Connect the Customer Status Contacts.Note: The wire for Customer Status Contacts must be routed in a conduit that is separate from AC input wiring. This wire must be isolated from the wiring for the AC voltage within the generator set start module.Serviceable Parts
