6.20 Checking Voltage to Long Terminal Strip
See Graphic: wc_gr003787
WARNING
Electric shock hazard. Only qualified personnel should conduct this
test. Do not perform this test if you or the machine are wet.
Complete this test with the machine running.
6.20.1 Remove the control panel front cover.
6.20.2 Place the main circuit breaker in the ON position.
6.20.3 Using the AC voltage setting on the multimeter, measure the voltage
between the R/G wire (a) and any of the neutral wires connected to the
long terminal strip. There should be 120V±10%.
If 120V±10% was not measured, shut down the machine and
check the continuity of the wiring back to the main circuit breaker.
Repair the wiring as necessary.
If 120V±10% was measured, continue.
6.20.4 Using the AC voltage setting on the multimeter, measure the voltage
between the B/G wire (b) and any of the neutral wires connected to the
long terminal strip. There should be 120V±10%.
If 120V±10% was not measured, shut down the machine and
check the continuity of the wiring back to the main circuit breaker.
Repair the wiring as necessary.
If 120V±10% was measured, the long terminal strip is receiving
the correct voltage.
