!
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 this unit does not exceed 16.5 VDC for
PST-150-12 or 33.0 VDC for PST-150-24 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-150-12 or 33.0 VDC for
PST-150-24
• 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-150-12 to 24V or 48V battery
system or PST-150-24 to the 48V Battery System)
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, external / internal DC fuses will blow and may also
cause permanent damage to the inverter.
!
CAUTION!
Damage caused by reverse polarity is not covered by warranty.
Use of External Fuse in DC Input Circuit
Use fuse of appropriate capacity within 7" of the battery Positive terminal. This fuse is
required to protect DC input cable run from damage due to short circuit along the length
of the cable. Please read instructions under Section 8.4.5 - Installation.
