6. CONNECTOR WIRING INFORMATION

CONNECTORS

Connectors for signal and power are UL-rated
screw-clamp terminal blocks that plug into
mating jacks on the printed circuit board.
Communication connectors are a single RJ11
plug for RS232, dual RJ11 plugs for RS485,
dual RJ45 plugs for RS485 Modbus, or USB.


Warning: Hazardous voltages may be present
on pins 4, 5 & 6 of P1 since digital ground is tied
to pin 3 of P5 (-Signal Input). Keep pin 3 close to
earth ground to minimize common mode voltage
or shock hazard at pins 4, 5 & 6 of P1.

Note: Control inputs 1 & 2 of P1 are menu
selectable.
