MULTIPLE CABINET SYSTEM

When connecting the two or more cabinets in parallel to make a Multiple Cabinet

System, follow the procedure as described below.

Install each cabinet as a single cabinet power source with each cabinet next to

each other. No side clearance is necessary. Connect the input wiring to each

cabinet. See figure 3.8.1 for a Multiple Cabinet System Outline.

Connect a paralleling cable PN (126088) between each cabinet of the paralleled

system. Connect one cable from Cabinet #1-P2 to Cabinet #2-P1. Connect

another cable from Cabinet #2-P2 to Cabinet #3-P1, etc. Connect as many

paralleling cables (up to eleven for a twelve cabinet system) as needed. This

paralleling cable contains all of the control signals necessary to operate the

Multiple Cabinet System.

All five output wires (Chassis, Neutral, Phase A, Phase B and Phase C) from

each cabinet need to be paralleled.

Cabinet to the output load connection MUST BE THE SAME LENGTH AND

WIRE SIZE. Refer to figure 3.8.2 for Multiple Cabinet System Wiring.

WHEN THREE OR MORE CABINETS ARE CONNECTED IN PARALLEL, A

PARALLELING / OUTPUT LOAD CENTER WITH INDIVIDUAL CIRCUIT BREAKERS

FOR EACH CABINET MUST BE INSTALLED TO PROTECT OUTPUT WIRING AND

For three or more cabinets in parallel an Output Load Center is REQUIRED. The

Output Load Center must contain INDIVIDUAL CIRCUIT BREAKERS, one for

each 3060-MS unit. The circuit breaker must be sized for the individual cabinet's

output voltage and frequency. Pacific Power's Part Number 716048, a 175 Amp

Circuit Breaker may be used for standard 120/208 volt direct coupled output.

Refer to modification or option documentation for other output voltage forms and

frequencies.
