ELECTRICAL WARNING: Ensure that power is disconnected from wiring
prior to handling! Check the voltage rating next to the power connector
- verify that it matches the power source.
1. Remove the plug portion of the power connector by loosening the two captive
mounting screws.
2. Strip back 1/4" off the insulation of the wires that will connect the unit to the
power source.
3. Loosen saddle screws and insert each conductor firmly into a terminal hole of
the plug (
note: this connection is not polarity sensitive.
)
4. Visually inspect that no strands of wire are straying out of the hole, potentially
shorting to ground or the other conductor. Tighten the saddle screws until the
wires are secure.
5. Re-insert the plug into the power connector and secure the two captive
mounting screws.

2.3.3 Connecting to the Console Port and the Alarm Port
2.3.3.1
Console Port
The Console Port enables configuration of the device and is connected by a serial cable to a PC.
For hardware installation see
"Connecting Network Cables"
, below. For startup and configuration
information see
MNS-DX Administrator’s Guide
.
2.3.3.2
Alarm Port
The alarm port carries alarm signals to provide notification of events specified by software configuration.
The events that can be set to trigger alarms are described in the
MNS-DX Administrator’s Guide
.
Wire the pins of the alarm port appropriately depending on whether your downstream alarm system expects
normally open or normally closed operation. See
Table 1-11
for alarm port pin-out. Table 2-1 below defines
the ratings of the alarm port contacts.
