After installing the SBC 7000 chassis to a rack and attaching necessary cables, you are now ready to install power and ground cables and apply power to the SBC. The SBC 7000 is capable of dual redundant AC or DC power.
The standard SBC 7000 is shipped with two power supplies. Please contact your sales representative for more information.

The following procedure explains how to ground the SBC 7000 to local earth using a 7/16 inch wrench:
Attach the two hole chassis ground lug PN 501-00526 to SBC 7000 using two flat washers PN 511-00376, two split lock washers PN 510-00056, and two hex nuts PN 511-00046.
Chassis Grounding Lug Location
Use the recommended 4AWG stranded copper cable for DC SBC 7000.
Connect the chassis to local earth ground such that any possible charge is carried off to the earth thus eliminating the risk of shock.
Route the power cables so that the left power supply cables connect from left side and the right power supply cables connect from right. This prevents one power supply cable from getting in the way of the other one in case it needs to be removed individually.
The following procedure explains how to connect to the Tectrol-specific AC power and powering on the switch:
For each AC power supply, insert the supplied AC power cord's female connector to the power supply AC receptacle at the rear of the chassis (shown in the following figure).

The following procedure explains how to connect to the ABB-specific AC power and powering on the switch:
For each AC power supply, insert the supplied AC power cord's female connector to the power supply AC receptacle at the rear of the chassis (shown in the following figure).

The following procedure explains how to disconnect from your local AC power source:
The following procedure explains how to connect an SBC 7000 power supply to the DC Power and power on the switch. If two power supplies are installed, both need to be connected to a power source before powering on the system.
Identify the correct size fuse(s) for your configuration and wire gauge before applying DC power to a switch; not to exceed 100A (recommended rating is 80A) fuse. Also, ensure to switch off the power supply before installing the cables.
Connect ground cable (green) to the lug to the right of the DC power terminal posts as shown in the below figure:
SBC DC Terminal Connections
If applicable, attach the other end of the supplied DC power cables to DC power source.
Do not apply DC power to the DC Power supply prior to hot-inserting the supply into the chassis.
The following procedure explains how to disconnect DC power from SBC 7000 series chassis:
Do not remove the DC Power supply without first turning off the power to the power supply being removed from the chassis.
Remove DC (or AC) power from the power supply and remove the power cables from power supply before attempting this procedure.
To remove the AC or DC power supply from the chassis, perform the following steps:
