10–18 kVA: If you have an external battery cabinet(s) with a DC switch, turn the switch to the ON position.

Turn the UPS ON/OFF switch to the ON position. The switch is located on the back of the 500 VA–3.1 kVA models and on the front of the 4.3–18 kVA models. The load should still be disconnected at this time.

After a short startup test, the READY indicator blinks for a few seconds and then remains illuminated. The UPS is ready to supply output power.

Turn the bypass switch to the UPS position.

Use an AC voltmeter to measure voltages on the terminal strip inside the bypass switch cabinet (refer to the label on the back of the switch’s lower front cover panel for the terminal numbers).

Record your measurements in the following chart according to the type of bypass switch installed. The voltages in the 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.

If the AC input voltage is 208V, measure 88 Vac between the AC output terminals:

:Internal Bypass Switch: 6 and 7 or 6 and 8

:External Bypass Switch: N and X1 or N and X2 DO NOT connect any 120V LOAD to the 88V terminals.
