De-Energize/Isolation Procedure
The following procedure should be followed to de-energize the PV100S for
maintenance.
To isolate the PV100S:
1. Turn the
ON / OFF switch to the OFF position.
2. Open the DC interface disconnect switch.
3. Open the AC interface disconnect switch.
4. Open the utility connection circuit breaker.
5. Install lockout devices on the utility connection circuit breaker and DC
disconnect switch.
Interconnection Standards Compliance
The PV100S has been tested and listed by Underwriters Laboratories to be in
compliance with UL1741 Static Inverters And Charge Controllers For Use In
Photovoltaic Power Systems, as well as IEEE-929-2000 Recommended Practice
For Utility Interface of Photovoltaic (PV) Systems.
IEEE-929-2000 provides guidance regarding equipment and functions necessary
to ensure compatible operation of photovoltaic systems which are connected in
parallel with the electric utility.
UL1741 is the standard applied by Underwriters Laboratory to the PV100S to
verify it meets the recommendations of IEEE-929-2000.
Refer to both documents for details of these recommendations and test
procedures.
WARNING
The terminals of the DC input may be energized if the PV arrays are energized. In
addition, allow 5 minutes for all capacitors within the main enclosure to discharge after
disconnecting the PV100S from AC and DC sources.
