The standard set point is 6 seconds.

3.10 Manual Bypass Switch Option
The manual bypass switch is a break before make switch located on the Power-Sure™ 700. The manual bypass
switch is used to bypass all power electronics in case of failure.
NOTE: This switch may be added in the field.
3.10.1 Normal Mode
With the switch in the normal position, the Power-Sure™ 700 will provide clean and regulated power to the critical
loads. The Power-Sure™ 700 should have the switch in the normal position unless a failure has occurred.
3.10.2 Bypass Mode
With the switch in the bypass position, the Power-Sure™ 700 will provide clean power to the critical loads. In the
bypass position, the unit will not regulate the incoming voltage. The Power-Sure™ 700 should be placed in the
bypass position when a failure of the system has occurred. This provides the user with some protection until a
service technician arrives.
CAUTION: PRIOR TO SWITCHING FROM ONE POSITION TO ANOTHER, TURN OFF THE
AC INPUT BREAKER. SOME SYSTEMS ARE EQUIPPED WITH PUSH-TO-TURN
SWITCHES. WITH THESE SWITCHES THE SWITCH WILL SHUNT TRIP THE
INPUT BREAKER WHEN PRESSED IN.
3.10.3 Remote Emergency Power OFF (REPO) (Optional)
The REPO is operated by a remote push button that when depressed will shunt trip the Power-Sure™ 700 input
breaker and disable the unit. This option may be added to units in the field. Contact the Customer Care Center if
you wish to add these options.
