4.8.3 Connection assignment
• For all electrical connections, use heat resistant wires or cable that is
rated for at least 194°F (90°C). Make sure that the wiring does not
touch the motor housing, the pump, or the piping.
• Power and control wires must be run in separate channels.
• Metal conduit for power wiring must only be attached to 1/2” NPT
conduit fitting.
• For a two pump connection, wire both pumps through a communi-
cation cable connecting the 2 RS-485 ports at the pumps to termi-
nals 15, 16 & 17 for single phase pumps and 5–6 & 7 for three phase
pumps.
• Low voltage wiring is recommended to be twisted pair and shield-
ed. Sensor wiring is not to exceed 65 feet (19.8 m) in length.
NOTICE:
Cable glands are only available for low voltage wiring to protect
against cable slippage and vapor ingress into the terminal box.
