5.7 Wiring Connections
The LPT-M digital transmitter is a low voltage powered device. Any application of operating
voltages higher than indicated in the specifi cation may result in damage. Double check wiring
connections prior to powering the transmitter. Damage from incorrect wiring connections or from
too much voltage applied is not covered under warranty.
All wiring should be run in EMT (or better) conduit properly earth grounded. All communications
(network) wiring must be in shielded cabling. Wire shielding must be connected together at each
device and taped off so it cannot cause a short on the circuit board when the door is closed. The
wiring shield should be connected to ground only at the controller, have a contiguous connection
throughout the net
work and be left taped and fl oating at the last device in the network. The
recommended 4 conductor, 16 AWG, shielded stranded wire cable types are AlphaWire 79220,
Belden 5202FE 008500 or equivalent.
