Safety / Installation

DANGER

HAZARDOUS VOLTAGE

(Can Cause Severe Injury or Death)

Turn OFF all power before installation, adjustment, or removal of transfer switch or any of its components.

The safe operation of your switch is GE Zenith’s focus. The proper storage, installation, operation and mainte- nance will help increase the life of the switch.

CAUTION

Due to hazardous voltage and current, GE Zenith rec- ommends that a GE Zenith Certified technician or a qualified electrician must perform the

installation and maintenance of the switch.

Equipment Inspection and Storage

Once you have received the transfer switch, inspect it for any damage. This includes damage to the enclosure, power panel, control panel and wiring harness. If any damage is found or suspected, file a claim as soon as possible with the carrier and notify the nearest GE Zenith representative.

Before installation, if it is necessary, store the transfer switch in a clean dry place, protected from dirt and water. Provide ample air circulation and heat, if neces- sary, to prevent condensation.
