Electrical Connections – Power and I/O connections are completed through screw actuated compression terminals.
Connector blocks can be removed from a module for wiring, as shown in the two figures below. Insert a small
straight-slot screwdriver between a connector block and the faceplate and use a gentle prying motion to separate the
connector block from the module. Each connector in a module is uniquely keyed. When installing a connector block,
be sure to fully insert the block in the module.

A snap-in MCX female connector is provided for the transceiver antenna connection.
Wire Stripping Recommendations:
Screw terminal wiring - 1/4" (6 mm) to 5/16" (8 mm)
Be careful not to nick the conductor or cut away strands.
Wire Selection - Stranded wire is recommended for most connections. Carefully select wire size, conductor
material, and insulation. Some selection considerations are:
• current and voltage to be carried
• total length of each wire run
• whether wire will be bundled or run singly
• indoor or outdoor installation
• temperature extremes (Use supply wires suitable for 5°C (10°F) above ambient temperature.)
• exposure to sunlight
• vibration
• types of contaminates
Wire Routing and Conduit - DC wiring should be separated from AC wiring and away from AC powered
pushbuttons, alarms, annunciators, motors, solenoids, and similar devices. Conduit and raceways are commonly
used for routing wiring. Wiring not installed in conduit or raceway should be clamped or supported approximately
every 12 inches (300 mm).
Power Input Circuit Protection
A circuit protection device must be installed in the power input circuit between the power source and the WiPS
transceiver or I/O module. Locate the protective device in a non-hazardous area unless suitable for use in a
hazardous area. Circuit protection can be provided by a circuit breaker, fuse or on-off switch accessible to the
operator, except where otherwise stated in this guide or by a certifying agency.
• AC to DC (converter) power supply – Typically, this power supply includes a fuse or circuit breaker in its
output circuit and often includes current limiting. An additional protective device at the module enclosure is
recommended. Check power supply specifications carefully.
• Battery power supply – This power system, because of the large amount of energy stored in a battery, must
include circuit protection.
