4. ELECTRICAL CONNECTIONS
See Table 4-1 for Barrier Terminal Block wire size and recommended tightening torque specifications.
WARNING! READ SAFETY NOTICES BEFORE ATTEMPTING TO USE THIS CONTROL.
DISCONNECT THE MAIN POWER BEFORE MAKING CONNECTIONS TO THE
CONTROL.
WARNING! TO AVOID ERRATIC OPERATION, DO NOT BUNDLE AC LINE AND MOTOR
WIRES WITH WIRES FROM SIGNAL FOLLOWING, START/STOP CONTACTS,
OR ANY OTHER SIGNAL WIRES. ALSO DO NOT BUNDLE MOTOR WIRES
FROM MULTIPLE CONTROLS IN THE SAME CONDUIT. USE SHIELDED
CABLES ON ALL SIGNAL CONNECTIONS OVER 12”, (30CM). THE SHIELD
SHOULD BE EARTH GROUNDED ON CONTROL SIDE ONLY. WIRE THE
CONTROL IN ACCORDANCE WITH NATIONAL ELECTRICAL CODE
REQUIREMENTS AND OTHER LOCAL CODES THAT APPLY.
WARNING! DO NOT CONNECT SWITCHES OR RELAYS IN SERIES WITH ARMATURE OR
CATASTROPHIC FAILURE WILL RESULT.
CAUTION! The Voltage Select Switch position must match the AC line input voltage
(“115” position for 115 Volt AC line input and “230” position (factory setting)
for 208/230 Volt AC line input).
CAUTION! If control is connected to a transformer, it is advisable to switch the
secondary to disconnect power. If the primary is switched, additional
snubber capacitors may have to be added across the transformer output to
prevent damage to the power bridge.
