SAFETY

SAFETY FEATURES

The PV-100208 enclosure contains exposed high voltage conductors. The enclosure
doors should remain locked, except during maintenance or testing. These servicing
instructions are for use by qualified personnel only. To reduce the risk of electric
shock, do not perform any servicing other than that specified in the operating
instructions unless you are qualified to do so. Do not open the cabinet doors if
extreme moisture is present (rain or heavy dew).
On/Off Switch
The PV-100208 incorporates a maintained position on/off switch located on the front door of the main
enclosure. Under normal conditions, the on/off switch is in the on position. Turning the switch to the
off position will initiate a controlled shutdown of the PV-100208 and open the A/C contactor within
the unit. The A/C contactor cannot be closed unless the switch is in the on position. The PV-100208 is
prevented from being restarted until the on/off switch is turned back to the on position. Cycling the on/
off switch will reset the PV-100208 and attempt to clear any system fault.
Main Enclosure Door Interlock Switch
The front door of the PV-100208 main enclosure is equipped with an interlock switch to preclude
operation in the event of the front door being opened. It is required that the PV-100208 main enclosure
door handle be padlocked during normal operation.
The PV-100208 will immediately shutdown if the front door is opened during
operation. It is required that the PV-100208 main enclosure door handle be pad-
locked during normal operations. Please make sure the unit is powered down, and
isolated from the utility grid and PV panels, prior to opening the front door. Allow
5 minutes for any stored potentials to be discharged, prior to opening the unit.
Disconnect Switches
Both AC & DC switches are equipped with lockout hasps for personnel safety. The switch enclosure
door will not open while the PV-100208 is running. In addition, the switch handle and shaft provide a
door interlock. The door cannot be opened when the switch is in the "on" position. The PV disconnect
switch is equipped with an auxiliary contact block which enables the switch to be used as a load break
PV disconnect. In the event a disconnect switch is opened while the PV-100208 is processing power
from the PV array, the contact block will signal the PCU to stop processing power before the switch
opens.
Fault Reporting
Any fault conditions are reported to the operator interface. The LCD will display a text description of
the fault. Refer to Section 5, Troubleshooting, for detailed descriptions of system fault conditions.
PV Ground Fault Detection
The PV-100208 is equipped with ground fault detection circuitry (see section 3, installation and sec-
tion 7, system schematic for further detail). Upon detection of 10 amps of ground fault current, the PV-
100208 executes an orderly shutdown, and annunciates a ground fault at the operator interface. The
