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.

Safety
viii 152607
General Safety Precautions
1. When installing the PV225S use only components recommended or sold by
Xantrex. Doing otherwise may result in a risk of fire, electric shock, injury to
persons, and will void the warranty.
2. Do not attempt to operate the PV225S if it has been dropped, or received more
than cosmetic damage during transport or shipping. If the PV225S is
damaged, or suspected to be damaged, see the Warranty section of this
manual.
3. To reduce the risk of electrical shock, lock-out and tag the PV225S before
attempting any maintenance, service, or cleaning.
Personal Safety
Follow these instructions to ensure your safety while working with the PV225S.
Safety Equipment
Authorized service personnel must be equipped with standard safety equipment
including the following:
• Safety glasses
• Ear protection
• Steel-toed safety boots
• Safety hard hats
• Padlocks and tags
• Appropriate meter to verify that the circuits are de-energized
(600 Vac and DC rated, minimum)
Check local safety regulations for other requirements.
Wiring Requirements
1. All wiring methods and materials shall be in accordance with the National
Electrical Code ANSI/NFPA 70. When sizing conductors and conduits
interfacing to the PV225S, both shall be in accordance with the National
Electric Code ANSI/NFPA 70, as well as all state and local code
requirements.
2. Use copper conductors only with insulation rated for 90 °C.
3. The PV225S has a three-phase output. It is marked with this symbol:
4. The AC power conductor wiring interfacing with the AC terminals in the
Transformer Enclosure are located at T6-X1, T6-X2, and T6-X3. These
terminals should be tightened to a torque value of 420 in-lb (47.5 Nm).
Conductors terminated to these terminals must use a crimp-on type ring
