Introduction

Operator Interface Controls

Operator interface controls are located on the front door of the main inverter enclosure. These controls include an ON/OFF Switch, 4-line LCD display and keypad called the Universal Frontpanel Control Unit (UFCU). Additionally there is an AC and DC Disconnect on the AC Interface Enclosure and the DC Interface Enclosure Doors.

Main Enclosure Door Interlock Switch

The front door of the PV100S main enclosure is equipped with an interlock switch to preclude operation while the front door is open. Opening the door of the main inverter enclosure will initiate an immediate controlled shutdown of the PV100S and opens both the main AC and DC contactors. The main AC and DC contactors cannot be closed unless the door’s interlock is in the engaged position. The PV100S is prevented from being restarted until the door is again closed and the switch is in the engaged position.

It is required that the PV100S main enclosure door must be locked during normal operation. The door interlock switch does NOT remove all hazardous voltages from inside the inverter. Before attempting to service the PV100S, follow the de-energize Lockout and Tag procedure on page 5–3.
