Control system interconnections (Figure 2.5) consist of UTILITY 1 and 2, LOAD 1 and 2; and leads 23 and

194.Control system interconnection leads must be run in a conduit that is separate from the AC power lead. Recommended wire gauge sizes for this wiring depends on the length of the wire, as recommended below:

	MAXIMUM WIRE LENGTH	RECOMMENDED WIRE
		SIZE
	460 feet (140m)	No. 18 AWG.
	461 to 730 feet (223m)	No. 16 AWG.
	731 to 1,160 feet (354m)	No. 14 AWG.
	1,161 to 1,850 feet (565m)	No. 12 AWG.

NOTE:

The preceding start circuit connections apply to the standard 2-wire start system only Your transfer switch may be equipped with a 3-wire connection system.

2.6AUXILIARY CONTACTS

If desired, you can access a set of Auxiliary Contacts on the Transfer Switch to operate customer acces- sories, remote advisory lights, or remote annunciator devices. A suitable power source must be connected to the COMMON (C) terminal. The contacts labeled 1, 2 and 3 (Figure 2.6) are connected at the factory for operation of transfer switch advisory lights. Contacts 4, 5 and 6 are available for customer use.

Figure 2.6 — Auxiliary Contact Schematic

Auxiliary contacts are rated 15 amperes at 125, 250 or 480 volts AC; 0.5 ampere at 125 volts DC; 0.25 ampere at 250 volts DC. DO NOT EXCEED THE RATED VOLTAGE AND CURRENT OF THE CONTACTS. Contact operation is shown in the following chart:
