Connect the Power Terminal

The chassis provides redundant power terminal inputs. Two sources of –48 VDC must be
provided to use the redundant power feature. The two power inputs are labeled –48V A and
–48V B
NOTE
A readily accessible disconnect device such as a rackmount fuse and alarm
panel that is suitably approved and rated, should be incorporated in the fixed
wiring.
NOTICE
The Total Access 5000 System is designed for a reliably grounded ‐48V
nominal DC supply. This requires the positive terminal to be referenced to
earth ground. Make this reference connection at either the source (rectifier or
battery) or at the frame. Powering by any other means may void the warranty
of the product.
To connect power to the chassis, complete the following:
1. Determine which fuse pairs are to supply power to the Total Access 5000 shelf and
2. Ensure the power is disconnected at the source.
3. Open the plastic power terminal doors on the rear of the chassis to access the power
4. Cut four lengths of appropriately sized wire to reach from the terminals on the fuse and
5. Strip 5/8 of an inch from the power and return wires, and using a crimping tool, connect
