To reduce the risk of SEVERE INJURY or DEATH:
• ANY maintenance to the operator or in the area near the operator MUST NOT be performed until
disconnecting the electrical power and locking-out the power via the operator power switch. Upon
completion of maintenance the area MUST be cleared and secured, at that time the unit may be returned
to service.
• DISCONNECT power at the fuse box BEFORE proceeding. Operator MUST be properly grounded
and connected in accordance with local electrical codes. The operator should be on a separate fused line
of adequate capacity.
• ALL electrical connections MUST be made by a qualified individual.
• DO NOT install ANY wiring or attempt to run the operator without consulting the wiring diagram. We
recommend that you install an optional reversing edge BEFORE proceeding with the control station installation.
• ALL power wiring should be on a dedicated circuit and well protected. The location of the power disconnect should
be visible and clearly labeled.
• ALL power and control wiring must be run in separate conduit.
• To avoid damage to door and operator, make ALL door locks inoperative. Secure lock(s) in “OPEN” position. If the
door lock needs to remain functional, install an interlock switch.
