Important Safety Instructions
SAVE THESE INSTRUCTIONS - DO NOT DISCARD
This manual contains important safety instructions for the PV100S that shall be
followed during installation and maintenance procedures.
WARNING: Shock Hazard
Read and keep this Planning and Installation Manual for future reference. Before
installing PV100S (either model), 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 PV100S enclosures contain exposed high-voltage conductors. The enclosure doors
should remain closed with the latches tightened, except during installation, 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 PV100S, 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 PV100S. 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.
