FIELD WIRING TERMINATIONS
Before applying voltage to the actuator, check that the electrical parameters (supply voltage and current)
shown on the nameplate, and on the attached wiring diagram, are correct for the installation.
Important: Cable or conduit connections must comply with all relevant safety and environmental
regulations.
WARNING: Do not disconnect the grounding connection X while terminating the field ground
connection.
Remove the plastic plugs from the cable entries. For all electrical connections, use components (cable glands,
cables, hoses, conduits) that meet the requirements of the particular application and of all applicable codes
and regulations. Screw the cable glands or conduit fittings tightly into the threaded entries. All connections
must be properly secured to ensure proper weatherproof and explosion-proof protection. Pull the cabling into
the electrical enclosures through the cable glands (or conduits) and terminate to the terminal board per the
applicable wiring diagram. Replace the plastic plugs of the unused cable entries with metal plugs. When all
wiring terminations are complete, check that the controls and signals work properly.
Two grounding studs, one(1) internal and one(1) external, are provided. It is recommended that a ground
connection be used for every installation.
Power supply cabling should be sized for the current produced by the actuator when running at its 100%
rating. Refer to the appropriate amperage charts.
