Connecting the DC Wiring Harness to the DC Source Voltage
After the internal DC power supply is installed, it must be connected to a DC power source. A
three-wire, 6-foot long DC wiring harness is included with the Summit X450a series DC switch and
internal DC power supply. The DC wiring harness must be properly connected to the DC source voltage
at your facility by a qualified electrician before the connector on the wiring harness can be attached to
the DC power supply socket on the switch. Figure 201 shows the wiring harness and connector.
The Summit X450a-24tDC or Summit X450a-24xDC 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 the Summit X450a-24tDC or Summit X450a-24xDC system
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.
