4 standard Models of Samlex America, Inc. DC Installation Kits are available to
cover installation requirements of 600 to 3500W inverters. Voltage drop of 2%
or less will be applicable for 3 ft. distance. In some cases, the kits may contain
thicker cables and higher rated fuses than the minimum sizes recommended.
Thicker cables will produce lower voltage drop and hence, will further
improve the overall efficiency. Also, voltage drop may be > 2% in some cases
for distances > 3 ft.
Dc input terminals for Battery connection
The DC input terminals for battery connection (8, 9) have cylindrical hole with set screw as
follows: Model PST-60S has an 8 mm cylindrical hole diameter with M-8 set screw and
Models PST-100S-150S and 200S have an 11 mm cylindrical hole diameter with M-8 set screw.
Using Proper Dc Wiring termination
The battery end and the inverter end of the DC input wiring should have proper termi-
nals that will ensure a firm and tight connection. The following Pin Type of terminals are
provided for crimping on to the inverter end of the DC input wires:
- PST-60S :
2 terminals PTNB35-20 for up to AWG #2 or 35 mm 2 wires
- PST-100S, PST-150S and PST-200S:
2 terminals PTNB50-20 for up to AWG #1/0 or 50 mm 2 wires
Reducing RF interference
To reduce the effect of radiated interference, twist the DC side cables. To further reduce
Rf interference, shield the cables with sheathing /copper foil / braiding.
taping Battery cables together to Reduce inductance
Do not keep the battery cables far apart. In case it is not convenient to twist the cables,
keep them taped together to reduce their inductance. Reduced inductance of the bat-
tery cables helps to reduce induced voltages. This reduces ripple in the battery cables
and improves performance and efficiency.

WARninG! Preventing Paralleling of the Ac output
1. The AC output of the inverter cannot be synchronized with another AC
source and hence, it is not suitable for paralleling. The AC output of the in-
verter should never be connected directly to an electrical breaker panel / load
