3.3 Wiring
3.3.1 Grounding
Grounding and wire routing help limit the effects of noise due to electromagnetic interference
(EMI). Run the ground connection from the ground screw to the grounding surface prior to
connecting devices.
3.3.2 Fault Relay
The two sets of relay contacts of the 6-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.
3.3.3 Redundant Power Inputs
The switch has two sets of power inputs, power input 1 and power input 2. The top two
contacts and the bottom two contacts of the 6-pin terminal block connector on the switch
‟s top
panel are used for the two digital inputs. Follow the steps below to wire redundant power
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
