Important Safety Instructions
SAVE THESE INSTRUCTIONS - DO NOT DISCARD
This manual contains important safety instructions for the PV225S that must be
followed during installation and maintenance procedures.
WARNING: Shock Hazard
Read and keep this Operation and Maintenance Manual for future reference.
Before installing the PV225S, read all instructions, cautionary markings, and all other
appropriate sections of this manual. Failure to adhere to these warnings could result in
severe shock or possible death. Exercise extreme caution at all times to prevent accidents.
WARNING: Shock Hazard
The PV225S enclosures contain exposed high voltage conductors. The enclosure doors
should remain closed with the latches tightened, except during maintenance or testing.
These servicing instructions are for use by qualified personnel who meet all local and state
code requirements for licensing and training for the installation of Electrical Power
Systems with AC and DC voltage to 600 volts. To reduce the risk of electric shock, do not
perform any servicing other than that specified in the installation instructions unless you
are qualified to do so. Do not open the cabinet doors if extreme moisture is present (rain or
heavy dew).
WARNING: Lethal Voltage
In order to remove all sources of voltage from the PV225S, the incoming power must be
de-energized at the source. This may be done at the main utility circuit breaker and by
opening the AC Disconnect and the DC Disconnect Switches on the PV225S. Review the
system configuration to determine all of the possible sources of energy. In addition, allow
5 minutes for the DC bus capacitors, located on the ceiling of the cabinet, to discharge
after removing power.
