Attaching the DC Wiring Harness to the DC Power Socket on the Switch
After the DC 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, Summit X450a-24xDC, or
Summit X450a-48tDC system without further electrician assistance.
NOTE
Be sure that the DC circuit is de-energized before you connect the DC wiring harness to the DC power socket.
CAUTION
Be sure that proper ESD controls are in use before switch maintenance is performed. This includes but is not
limited to wrist straps that are grounded to the switch chassis and earth grounds.
To attach the DC wiring harness to the internal DC power supply, perform the following steps:
