Operation
The Power-Sure 700 is operated by simply turning on the
main AC input circuit breaker. All units 50 kVA and larger are
equipped with a bypass switch as a standard feature. For
units 45 kVA and smaller, the bypass switch is optional. This
is a no load switch and MUST only be operated when the
unit is OFF. The bypass switch should be in the “NORMAL”
position unless a problem occurs with the system. If a
problem occurs, turn OFF the main AC circuit breaker
and turn the bypass switch to the “BYPASS” position.
Re-energize the system by turning on the AC circuit breaker
and contact the Customer Support Department for repairs.
Any “ALERT” condition requires the main AC input breaker
to be turned off in order to reset the “ALERT” light.
FOR ASSISTANCE, CALL 1-800-809-2772, option 4, and
then option 2.
