Transformer Connection Alert
***** CAUTION *****
DRIVES WILL BE DAMAGED BY INCORRECT POWER CONNECTION
Disconnect transformer entirely from power supply.
Check resistance between transformer ground wire and each secondary leg.
If resistance is more than 1 or 2 ohms, then the transformer ground wire is not
connected to a neutral point within the secondary windings.
or
Disconnect transformer entirely from power supply.
Remove transformer cover and follow transformer ground wire to determine if it is
merely a case ground or if it actually goes to a neutral point within the secondary
windings.
or
Check voltages between each secondary leg and ground.
If they are not equal, the secondary windings are “floating” with respect to ground.
THE GROUND WIRE GOING INTO THE MACHINE MUST BE CONNECTED
TO A NEUTRAL POINT WITHIN THE SECONDARY WINDINGS
AND TO EARTH GROUND.
The secondary windings must be grounded.
Voltages between each secondary leg and ground should be equal, half the voltage
between secondary legs.

Electrical Safety Rules
Read and understand the following list of cautions before attempting to perform service on this
equipment. Failure to observe these rules can result in death or serious injury.
Caution
· Beware of High Voltage present within the machine’s electrical cabinet
· Do not attempt to service electrical components unless you are qualified to work on them
safely
· Only qualified personnel should attempt to make current and voltage readings
· Always turn the main power off before servicing components within the electrical cabinet
· Always keep hands and fingers away from live electrical terminals
· Remove jewelry while servicing the machine to avoid shorting any electrical circuits
· Allow all components to discharge before servicing them, wait at least 15 seconds after
powering off, before servicing
FAILURE TO FOLLOW THESE RULES CAN RESULT IN SERIOUS INJURY OR DEATH
