safety Instructions

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 /
motorhome / caravan.
Preventing Dc input over Voltage
It is to be ensured that the DC input voltage of this unit does not exceed 16.5 VDC for
the PST-300S-12E or 33.0 VDC for the PST-300S-24E 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 the PST-300S-12E or 33.0
VDC for PST-300S-24E.
• Do not use unregulated solar panels to charge the battery connected to this unit.
Under cold ambient temperatures, the output of the solar panel may reach > 22 VDC
for 12V Battery System and > 44 VDC for the 24V Battery system. Always use a charge
controller between the solar panel and the battery.
• Do not connect this unit to a battery system with a voltage higher than the rated bat-
tery input voltage of the unit (e.g. do not connect PST-300S-12E to 24V or 48V battery
system or PST-300S-24E to the 48V Battery System)
• 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.
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, the external DC fuse and theDC fuses inside the
inverter will blow and may also cause permanent damage to the inverter.

Damage caused by reverse polarity is not covered by warranty.
