De-Energize/Isolation Procedure
The following procedure should be followed to de-energize the Xantrex GT250 E
for maintenance.
To isolate the Xantrex GT250 E:
1. Turn the
ON/OFF switch to the OFF position.
2. Open the DC interface disconnect switch (-Q11).
3. Open the AC interface disconnect switch (-Q1).
4. Open the utility connection circuit breaker.
5. Install lockout devices on the utility connection circuit breaker, AC and DC
disconnect switch.
Interconnection Standards Compliance
The Xantrex GT250 E complies with the German grid protection requirements of
VDEW and the Spanish RD 1663/2000.
The Xantrex GT250 E is designed to meet UL 1741 Static Inverters And Charge
Controllers For Use In Photovoltaic Power Systems, as well as IEEE 519.
Refer to both documents for details of these recommendations and test
procedures.
Intended Use
The Xantrex GT250 E may only be used in connection with PV modules. It is not
suitable for any other application areas.
An initial operation (e.g. starting the intended operation) will only be allowed
when observing the EMC guideline (89/336/EWG).
The Xantrex GT250 E complies with the 73/23/EWG low voltage directive
requirements. The harmonized standards of the series EN 50178/DIN VDE 0160
in connection with EN 60439-1/DIN VDE 0660 part 500 and EN 60146/DIN VDE
0558 will be used for the inverters.
WARNING
The terminals of the DC input may be energized if the PV arrays are energized. In
addition, allow 20 minutes for all capacitors within the main Enclosure to
discharge after disconnecting the Xantrex GT250 E from AC and DC sources.
