1.3 SAFETY INSTRUCTIONS - INVERTER RELATED
WARNING!
Preventing Paralleling of the AC Output
The AC output of the unit should never be connected directly to an Electrical Breaker Panel / Load
Centre which is also fed from the utility power / generator. Such a direct connection may result in
parallel operation of the different power sources and AC power from the utility / generator will be fed
back into the unit which will instantly damage the output section of the unit and may also pose a fire
and safety hazard. If an Electrical Breaker Panel / Load Center is fed from this unit and this panel is also
required to be fed from additional alternate AC sources, the AC power from all the AC sources (like
the utility / generator / this inverter) should first be fed to an Automatic / Manual Selector Switch and
the output of the Selector Switch should be connected to the Electrical Breaker Panel / Load Center.
Samlex America, Inc. Automatic Transfer Switch Model No. STS-30 is recommended for this application.
!
CAUTION!
To prevent possibility of paralleling and severe damage to the unit, never use a simple jumper cable with a
male plug on both ends to connect the AC output of the unit to a handy wall receptacle in the home / RV.
Preventing DC Input Over Voltage
It is to be ensured that the DC input voltage of these units is up to 34 VDC for PSR-1200-24 and up to 60VDC
for PSR-1200-48 to prevent permanent damage to the unit. Please observe the following precautions:
• Ensure that the maximum charging voltage of the external battery charger / alternator / solar charge
controller is up to 34 VDC for PSR-1200-24 and up to 60VDC for PSR-1200-48.
• Do not use unregulated solar panels to charge the battery connected to this unit. Under cold ambient
temperatures, the output of the solar panel / array may reach higher than the limiting voltages
specified above. Always use a charge controller between the solar panel and the battery.
• When using Diversion Charge Control Mode in a charge controller, the solar / wind / hydro source
is directly connected to the battery bank. In this case, the controller will divert excess current to an
external load. As the battery charges, the diversion duty cycle will increase. When the battery is
fully charged, all the source energy will flow into the diversion load if there are no other loads. The
charge controller will disconnect the diversion load if the current rating of the controller is exceeded.
Disconnection of the diversion load may damage the battery as well as the inverter or other DC loads
connected to the battery due to high voltages generated during conditions of high winds (for wind
generators), high water flow rates (for hydro generators). It is, therefore, to be ensured that the
diversion load is sized correctly to prevent the above over voltage conditions.
• These units are designed to operate from Battery System with nominal voltage of 24 VDC (PSR-1200-24) or
48 VDC (PSR-1200-48). Do not operate these units from a battery system voltage higher / lower than their
rated nominal voltages.
Preventing Reverse Polarity on the Input Side
When making battery connections on the input side, make sure that the polarity of battery connections
is correct (Connect the Positive of the battery to the Positive terminal of the unit and the Negative of the
battery to the Negative terminal of the unit). If the input is connected in reverse polarity, the external DC
fuse and the DC fuses inside the inverter will blow and may also cause permanent damage to the inverter.
