Section 9: Electrical Connection
• Move valve to mid-position by handwheel. This will allow sufcient time to stop
actuator in case of improper hook-up or reversed power phases.
• Identify means of removing power during hookup.
• Be sure no erroneous remote control signals can be received causing actuator
to energize.
• Electrically operate the valve in the open direction. If the valve closes, actuator
must be stopped and the power leads reversed to correct voltage phasing or
improper eld wiring.
• Set all eld conduit entries in accordance with National Electric Code Requirements.

WARNING
Improper power voltage phasing eliminates protection of both the position limit switch and
torque switches, risking valve damage.
