Connecting the dryer transformer
Power for the refrigeration dryer (if one is present) is provided by a transformer. This is not required
for 460 V power supply.
Do only use terminal 0V–208V–230V (primary side of the transformer) for changing the main
voltage connection. Do not change the terminal 0V–460V. This terminal is readily wired.
1. Open the control cabinet and insert the jumpers in the terminal strip ---X31 in accordance with
the electrical diagram.
2. If necessary:
Open the left access door and connect the transformer in accordance with the electrical diagram.
