Wiring
System Start-up: Step 2
Wire the transmitter connections with the power
off. Keep any 4 to 20 mA and relay-actuated output
devices that are connected to it offl ine at this time.
Wire the sensor (pg. 7), power (pg. 8) and Open
Collector and relay(s) (pg. 9).
Wiring Tips:
• Do not route the sensor or DC power cables in conduit
containing AC power wiring. Electrical noise may
interfere with sensor signal.
• Routing the sensor cable in grounded metal conduit can
help prevent electrical noise and mechanical damage.
• Seal the cable entry points to prevent moisture damage.
• Only one wire should be inserted into a terminal.
• Splice double wires outside the terminal or use appropriate
wire ferrule, not to exceed 2 mm (0.08 in) diameter.
Doing so may cause damage to 9900 Transmitter,
Relay Module, and Batch Module.
All wiring connections to the 9900-1BC are made via
removable terminal plugs.
In general:
• Terminals accept 12 to 24 AWG wire.
• Strip 7 mm (0.28 in.) of insulation from wire tips and tin
bare ends to eliminate fraying.
• Insert wire tip or ferrule completely into the terminal and
secure with the screw.
• Do not allow any AC leads that may be connected to the
internal relays to come in contact with low voltage wiring.
Avoid Electrostatic Discharge (ESD)
• Minimize handling of plug-in modules to reduce the
possibility of damage due to ESD.
• Handle modules by the edges. Never touch any
exposed circuitry or contacts.
• Wear an anti-static wristband or stand on an anti-
static mat, or keep one hand touching a properly
grounded pipe or other properly grounded piece of
metal when handling modules.
