3.3 Wiring
WARNING
Be sure to switch off the power and make sure the area is not hazardous before
disconnecting modules or wires. 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
devices.
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
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.
