Npower Installation - Liebert OpenComms Installation & User Manual

NPower Installation

As a minimum there will be an IFM board (communications
interface) mounted at the mid-point on the door. Other options
may also have been previously installed.
The Option boards mount on the inside of the option door.
Options can be located in any available option slot, however the
OpenComms – Network Interface Card should be mounted in
the topmost (top cable entry) or bottom most (bottom cable
entry) position.
Power Connection for NPower
After mounting the NIC card in the uppermost or lowermost
option position, per the instructions above, route the wire harness
from TB3 on the lower left of the NIC card to the power supply
board on the back of the control door. Follow the routing path
indicated in Fig 7.
Communication Connection for NPower
Connect the 2-wire harness from TB1 on the bottom center of
the NIC card to TB55 on the IFM card. The board is now ready
to connect customer inputs, which should be routed from either
the top or bottom cable entry points.
Refer to the Npower option manual for any further details on
installation.
