Connecting the DC Wiring Harness to the DC Source Voltage
A three-wire, 6-foot long DC wiring harness is included with the Summit family DC-powered switch.
The DC wiring harness must be properly connected to the DC source voltage at your facility by a
qualified electrician before you attach the connector on the wiring harness to the DC power supply
socket on the switch. Figure 139 shows the wiring harness and connector. For information about the
wire-to-pin connection, see Table 90 on page 419.
The Summit DC-powered switch and rack must be connected to protective earth ground before installing
any switch components.
Wiring the DC input power harness to your facilities DC source voltage must be performed by a qualified, licensed
electrician. After the wiring harness is connected to a permanent DC voltage source by a qualified, licensed
electrician, you can remove, replace and maintain a Summit DC-powered switch without further electrician
assistance. However, always be sure that the DC circuit is de-energized before connecting or disconnecting the DC
power connections at the rear of the switch.
The DC wiring harness must be properly connected to a DC main circuit breaker rated no greater
than 20 A.
Provide proper connection and strain relief on the DC wiring harness in accordance with all local and national
electrical codes.

Each wire on the harness has been properly marked for proper attachment to the DC power source. Leave
these labels on each lead wire for future reference.
