3.0 Installation, continued
3.1 Installation Procedure
The VMX Power Supply has been designed for shelf mounting in the horizontal confi guration
or wall-mounting in the vertical confi guration.
1. Before installing the power supply, inspect for damage, loose connectors, or other
potential failures. Correct discrepancies before proceeding.
2. For horizontal confi gurations, place the VMX Power Supply on the appropriate enclosure
mounting shelf. The unit is placed in the lower-right compartment of PME enclosures, the
upper compartment of PWE, UPE, UPE/M Enclosures, and on the equipment trays of PN
Series enclosures.
For vertical confi gurations, mount the VMX Power Supply securely to a wall allowing for
plenty of space for connections and servicing (vertical dimensions in/mm: H 11.7/297 x W
20/508 x D 9/229).
Alpha enclosures are designed to properly vent the VMX Power Supply. If using a non-Alpha enclosure, it is
the customer’s responsibility to ensure the VMX Power Supply remains within its environmental specifi cations.
NOTE:
Batteries are an important part of the VMX Power Supply. Properly install and test all batteries,
battery connections, and battery cables before connecting to the power supply.
CAUTION!
