IMPORTANT SAFETY INSTRUCTIONS
8 / 79
Do not operate or maintain the inverter until at least 5 minutes after
disconnecting all sources from DC and AC sides.
The DC conductors of this PV system are normally ungrounded but
will become intermittently grounded without indication when the
inverter measures the PV array isolation.
If there is a fault and it is unsafe to access the inverter:
1.
Notify someone else. Initiate emergency mitigation plan if necessary.
If smoke or fire exists, procure a fire extinguisher.
2.
If a fire has escaped the inverter enclosure – notify 911 immediately!
3.
Turn OFF the AC feed breaker as soon as possible/safe.
4.
If safe but conditions are deteriorating, consider:
a)
Using the fire extinguisher.
b)
Cutting the string conductors – one cable at a time with
insulated cutters (while wearing appropriate PPE).
5.
Monitor conditions until low irradiation ~30min prior to sunset. If safe,
turn OFF DC switches on the inverter and AC switches/disconnect
external to the inverter and proceed with normal troubleshooting
procedures, refer to Troubleshooting chapter.
WARNING!
All the installation and wiring connections should be performed only
by qualified technical personnel. Disconnect the inverter from PV
modules and the AC grid before maintaining and operating the
equipment.
Risk of electric shock and fire.
Use only with PV modules that in
conformance with the maximum system voltage.
Electric shock Hazard.
The DC conductors of this photovoltaic
system are normally ungrounded but will become intermittently
grounded without indication when the inverter measures the PV array
isolation.
Shock Hazard.
The inverter is energized from both AC and DC
sources. Disconnect all sources before servicing.
The DC Switch is rated to break loads under normal operating
conditions. However, a DC short circuit could be hazardous and the
following procedures should be followed before turning OFF the DC
Switch under fault conditions.
CAUTION!
Please ensure the mounting bracket is properly installed before
hanging the inverter and wire-box on the bracket.
This AFCI device automatically resets and may only be used when
allowed by NFPA 70 and CSA C22.1.
