first column should be nearly equal to the voltages in the second column. If the values differ by more than
a few volts, check the terminal strip connections and correct any wiring problems.

10. If the bypass switch is a Break-Before-Make, skip this step and proceed to step 11. If the bypass switch is
a Make-Before-Break type ,verify that the AC voltages from the UPS and the AC line are in phase. Measure
the voltage between the following points on the terminal strip. These measurements must be no more
than 100 Vac; if they are, call your service representative.
External Bypass Switch (BPE-02, BPE-04, or BPE-05)
7 to 11 Vac
8 to 12 Vac
11. Measure the AC voltage between the following points on the terminal strip. This reading must be no more
then 1 Vac; if it is, call your service representative.
External Bypass Switch (BPE-02, BPE-04, or BPE-05)
6 to 10 Vac
8 to 12 Vac
12. Turn the bypass switch to the LINE position. Measure the voltage to the protected equipment and verify it
is correct.
13. Turn the bypass switch to the UPS position and verify the voltage to the protected equipment is still
correct.
