Connect DC Power

Warning	A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. Statement 1022
Warning	This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a UL Listed
	and Certified fuse or circuit breaker no larger than 60 VDC, 15 A is used on all current-carrying conductors.
	Statement 96

If you ordered the universal gateway with a DC-input power supply, follow the directions in this section for proper wiring.

Caution In a DC power supply installation, do not connect the 48 VDC Return wire to chassis ground at the universal gateway. A single-point ground is recommended at the power distribution rack.

Note This product is intended for installation in restricted access areas and is approved for connection using number 12 or number 14 AWG copper conductors only. The installation must comply with all applicable codes.

To connect DC power, follow these steps:

Step 1 Remove power from the DC circuit.

Warning	Before connecting or disconnecting ground or power wires to the chassis, ensure that power is removed from the
	DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC
	circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF
	position. Statement 140
