Safety Instructions
1.3.2 Preventing DC Input Over Voltage
It is to be ensured that the DC input voltage does not exceed 16.5 VDC for PST-1000-12
or 33.0 VDC for PST-1000-24 to prevent permanent damage to the unit. Please observe
the following precautions:
• Ensure that the maximum charging voltage of the external battery charger / alterna-
tor / solar charge controller does not exceed 16.5 VDC for PST-1000-12 or 33.0 for
PST-1000-24.
• Do not connect this unit to a battery system with a voltage higher than the rated
nominal battery input voltage of the unit.
• 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 discon-
nect the diversion load if the current rating of the Controller is exceeded. Disconnec-
tion 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.
• Do not use solar panel/array to directly charge the battery bank connected to the
inverter. Use appropriate Charge Controller between the solar panel/array and the
battery bank. Using solar panel/array to directly charge the battery will lead to over
voltage shutdown of the inverter and the possible damage due to battery voltage ris-
ing close to the level of the open circuit voltage of the solar panel(s) when the battery
is fully charged and is in Float stage
(under this condition, the battery will be drawing
very low trickle charge current & the voltage of the unregulated solar panel/array will
rise close to its Open Circuit Voltage)
.
1.3.3 Preventing Reverse Polarity on the Input Side
When making battery connections on the input side, make sure that the polarity of bat-
tery 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, DC fuse(s) inside the inverter will blow and may also
cause permanent damage to the inverter.
!
CAUTION!
Damage caused by reverse polarity is not covered by warranty.

ATTENTION!
Les dommages causés par l'inversion de polarité ne sont pas couverts par la garantie.
