INSTALLATION AND OPERATION MANUAL
CNGE24MS-OB(M,S)
TECH SUPPORT: 1.888.678.9427
Step 1: Install the L-shape mounting kits provided in the package to the left and right of the
device.
Step 2: With front brackets orientated in front of the rack, mount the device in the rack with four
rack-mounting screws.
Wiring
WARNING: Do not disconnect modules or wires unless power has been switched off or the area
is known to be non-hazardous. The devices may only be connected to the supply voltage shown
on the type plate.
ATTENTION
1. Be sure to disconnect the power cord before installing and/or wiring your switches.
2. Calculate the maximum possible current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each wire size.
3. If the current goes above the maximum ratings, the wiring could overheat, causing serious
damage to your equipment.
4. Use separate paths to route wiring for power and devices. If power wiring and device wiring
paths must cross, make sure the wires are perpendicular at the intersection point.
5. Do not run signal or communications wiring and power wiring through the same wire conduit.
To avoid interference, wires with different signal characteristics should be routed separately.
6. You can use the type of signal transmitted through a wire to determine which wires should be
kept separate. The rule of thumb is that wiring sharing similar electrical characteristics can be
bundled together
7. You should separate input wiring from output wiring
8. It is advised to label the wiring to all devices in the system
Fault Relay
The relay contacts of the 4-pin terminal block connector are used to detect user-configured
events. The two wires attached to the fault contacts form an open circuit when a user-configured
when an event is triggered. If a user-configured event does not occur, the fault circuit remains
closed.
