SECTION 1 |
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-1500-12 / PST-2000-12 or 33.0 VDC for PST-1500-24 / PST-2000-24 to prevent perma-
nent 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-1500-12 / PST-2000-12 or
33.0 VDC for PST-1500-24 / PST-2000-24
• 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-1500-12 / PST-2000-12 to 24V or
48V battery system or PST-1500-24 / PST-2000-24 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 the DC 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.
Use of External Fuse in DC Input Circuit
Use Class-T or equivalent fuse of appropriate capacity within 7" of the battery Positive ter-
minal. 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.
Hard Wiring of AC Output to AC Panelboards in RVs / Motor Homes / Trailers /Campers
WARNING!
RISK OF ELECTRIC SHOCK
When this unit is installed in RV / Motor Homes / Trailers / Campers and hard-
wiring connection is used to feed the AC output of the inverter to the AC Distri-
bution Panelboard / Load Center in the vehicle, it is to be ensured that Ground
Fault Circuit Interrupter(s) [GFCI]are installed in the vehicle wiring system to
protect branch circuits.
The following GFCI has been tested to operate satisfactorily and are acceptable. Other
types may fail to operate properly when connected to this inverter:
