Table 2-4: AC Voltage Measurements
Step Action
7a – Measure the AC voltage from terminal L2 to neutral on the North American cabinet.
–– Voltage should be in the nominal range of 115 to 120 Vac.
7b – Measure the AC voltage from terminal L2 to ground on the North American cabinet.
–– Voltage should be in the nominal range of 115 to 120 Vac.
7c
! CAUTION
If the AC voltages measured (on the North American cabinet) in the following step exceeds 240 V
when measuring between terminals L1 and L2, STOP and DO NOT proceed until the cause of the
higher voltages are determined. The frame will be damaged if the Main breaker is turned on with
excessive voltage on the inputs.
– Measure from terminal L1 to terminal L2.
–– Voltage should be in the nominal range from 208 to 240 Vac.
8 Remove external AC power from the frame by setting the facility circuit breaker to OFF.
9 Install the ACLC front panel assembly and secure with the four screws removed in step 1.
10 Apply external AC power to the frame by setting the facility circuit breaker to ON.
