Measuring voltage on output: Load circuit breakers are off but I'm measuring DC voltage on the
•
output terminal block.
This is normal. The load breakers are monitored electronically via a diode to a digital input
on the EM4x. This is a high impedance residual voltage and does not present a hazard to
the
AC Meter Shows Incorrect Voltage
•
Meter requires greater than a 2-amp load to measure correctly
EM4x Module does not stay in place
•
On the left side of the module is a small ball screw that can be adjusted to maintain
proper holding force of the EM4x inside the chaise.
Rectifiers come out of shelf
•
Verify that the rectifier is fully inserted and using a small flathead screwdriver the green locking tab
on the right side is pressed down.
No output from rectifiers
•
Verify correct AC input voltage:
Confirm operation voltages between each set of Line inputs A, B, and C:
A-L1 to A-L2 = 208 or 230 volts, B-L1 to B-L2 = 208 or 230 volts, C-L1 to C-L2 = 208 or 230
volts
Check voltages between each set of Line inputs and ground:
A-L1 to Ground = 208 or 230 volts, B-L1 to Ground = 208 or 230 volts, C-L1 to Ground = 208
or 230 volts
A-L2 to Ground = 208 or 230 volts, B-L2 to Ground = 208 or 230 volts, C-L2 to Ground = 208
or 230 volts
