3.2 Electrical Hook Up
Step 1. Move valve to mid-position by handwheel. This will allow sufcient time to
stop actuator in case of improper hookup or reversed power phases.
Step 2. Identify a means of removing power from actuator during check out.
Step 3. Be sure no erroneous remote control signal can be received causing actuator
to energize.
Step 4. Energize Open control to check operation of contactor and push buttons.
Open controls must move valve in Open direction. If valve Closes, actuator
must be stopped and the power leads reversed to correct voltage phasing or
improper eld wiring.
CAUTION:
If voltage is improperly phased, Torque and Limit Switches are not in circuit to protect valve.
Step 5. Seal all eld conduit entries in accordance with National Electric Code
requirements
