WARNING: Disconnect primary power prior to servicing.

Maxiva ULX COFDM Series
STEP 3
Connect the safety ground wire to the stud shown in Figure 2-4.
There should be separate safety ground wires for each AC mains input.

STEP 4
Verify that the Primary AC line voltage is correct for the MOV
board and jumper configurations. Measure the primary AC line
voltage from phase to phase and write it in the blank below. The
transmitter was setup in the factory with 208/220/240VAC Delta or
Wye, or 380/400/415VAC WYE 3 phase configuration on the IPA and
PA backplanes, on TB1 and TB2 on the AC distribution panel, on the
MOV boards, and by including a neutral connection from the AC
service disconnect to CB23 and CB24 for 380 to 415 VAC WYE
connections. Make sure that the transmitter is setup for the same AC
power configuration that is used at the site. Check the on site measured
AC voltages against the factory test data sheet or the metal ID plate
affixed to the transmitter cabinet.
STEP 5
Record measured voltage for each phase and record them below.
1 to 2: VAC
2 to 3: VAC
1 to 3: VAC
NOTE:
There must be less than a 10% imbalance between any one phase and the average
of all three phases to allow the transmitter to operate, however the phase imbal-
ance and frequency variation must be 5% or less to meet transmitter specifica-
tions.
