PROCEDURE

1. If you have a 60V model, skip to step 3. If you have a 60/72/90V or 60/90V

model, continue to step 2.

2. For 60/72/90V and 60/90V Models Only. Select the output voltage by plugging

the output connector into the desired voltage source. The output connector is yellow

and is located towards the rear of the chassis. The voltage source connectors are

located towards the front of the chassis:

Red = 87 Vac White = 72 Vac Yellow = 60 Vac

Locate the proper source connector for your cable company voltage and plug it into the

yellow output connector.

NOTE:The connection for selecting output voltage is inside the ZTT/Plus chassis

along the main wire harness in the center of the chassis; it is accessible when

the inverter module is removed.
