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 this unit does not exceed 16.5 VDC for
the PST-3000-12 or 33.0 VDC for the PST-3000-24 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 the PST-3000-12 or 33.0 VDC
for PST-3000-24
• 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-3000-12 to 24V or 48V battery
system or PST-3000-24 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, the external DC fuse and theDC fuses 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.
