Transformer Wiring Configuration (4000 and 4400 Watt Systems Only):
If the origin of the input power is 208 volts 3 phase, the system can only be powered byone of the following methods: one hot (120 volts) or using an isolation transformer inline when 2 hots (240 volts). This will avoid having a phase mismatch which will cause damage to the unit’s inverter. Medi-Products does not supply this transformer, we recommend contacting your local electrical supply house and reference the Hamond model number below.

Use the following diagrams to power the unit for applications where 3 phase power is the origin of the input power:
