Wiring the Actuator
Turn off all power and lockout/tag out service panel before installing or modifying any
electrical wiring.
1. Remove the actuator cover. Keep the cover on hand for reference.
2. Wire the actuator according to the wiring diagram attached to the inside of the
actuator cover.
● Power and control wiring should use separate conduit entries.
● A minimum of 18 AWG wire is recommended for all field wiring.
● Terminals directly mounted on the actuator switch plate accept wire sizes ranging
from 14 to 22 AWG.
● Terminals of internally-mounted electronics modules accept wire sizes ranging
from 14 to 24 AWG
● The conduit connections must be properly sealed to maintain the weatherproof
integrity of the actuator enclosure.
When wiring an A-Series 530 lb-in actuator for two-position (On/Off) control:
If the power to the actuator is commanded to be off, you must ensure that there is no
extraneous or leakage voltage between hot and common. Leakage voltage greater
than 3 Vac can cause actuator failure.
The controller should use at minimum, a one-second time delay for command signal
reversal. Instantaneous command reversals may cause actuator failure.
Setting Travel Limit Switches
If the unit came assembled to a valve, the switches have been factory-set and DO
NOT need adjustment.
