SAFETY FEATURES
WARNING
The PV-30208 enclosure contains exposed high voltage conductors. The upper enclosure access panel should remain closed, 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 remove the front access panel if extreme moisture is present (rain or heavy dew).
On/Off Switch
The PV-30208 incorporates a maintained position on/off switch located on the upper enclosure. Under normal conditions, the on/off switch in the on position. Turning the switch to the off position will initiate a controlled shutdown of the PV-30208 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-30208 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-30208 and attempt to clear any system fault.
Enclosure Front Access Panel
The front access panel of the PV-30208 upper enclosure is fastened with twelve M6 stainless steel hex nuts. It is required that the PV-30208 enclosure front panel be securely fastened during normal opera- tion.
WARNING
The PV-30208 does not incorporate a door interlock switch. Please make sure the unit is powered down, and isolated from the utility grid and PV panels, prior to opening the front access panel. Allow 5 minutes for any stored potentials to be discharged prior to opening the unit. The front access panel of the PV-30208 upper enclosure must be securely fastened during normal operation.
Fault Reporting
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-30208 is equipped with ground fault detection circuitry (see Section 3, Installation and Section 7, system schematic for further detail). Upon detection of 10 amps of ground fault current, the PV- 30208 executes an orderly shutdown, and annunciates a ground fault at the operator interface. The PV- 30208 will remain faulted until the ground fault is remedied and cleared at the operator interface (see section 5, troubleshooting). To enable this feature for monopolar pv array configuration, a jumper is installed between TBDC- and TB NEUT on the PV input terminal block. This must be the only point of PV conductor ground. Monopolar pv array configuration is enabled by default (for a detailed descrip- tion of bipolar and monopolar pv array configurations, see Section 4, Operation Features).
