Remote functions wires carry very low voltage signals. They operate on TTL ground
levels. The Remote Functions wires should be shielded and routed away from the

false ground triggering. Maximum length 60 inches.
• The HI 2160RC
PLUS
is factory configured to operate from either
120 or 240 VAC, 50 or 60 Hz power. Check the model number of
your unit to verify the voltage. If the unit is configured for 240
VAC, a "B2" will be printed on the name plate.
• The power and relay circuit card filters conditions AC power. How-

Contact Customer Support for more information.
• The AC power should be supplied by a "clean" primary line,
directly from the power panel. This line should not supply any other
