Ac output cable Sizing & conductor termination for Hard-wiring
Use 3 conductor cable with at least 90 C insulation rating. Based on the maximum output
current of 12.5A for PST-1500 and 16.7A for PST-2000, the minimum size of each of the 3
conductors of the AC output cable should be AWG #12 for both the inverters. This is the
minimum size recommended in NEC Table 310.17 for up to 20A over current protection. for
firm connection when using set screw type of terminals, use Insulated Pin Type of Terminals
for termination of the Line and Neutral conductors and Non Insulated Ring Type of Terminal
for the Grounding conductor. for convenience, the following terminals have been provided:
For Line and neutral wires: Nylon Insulated, Cord End
Terminals for AWG #12 wire ........................................................................ 2 pieces
For neutral wire: Non Insulated Ring Terminal for #6 stud ....................... 1 piece
Use proper crimping Tool to crimp the terminals to the bare ends of the wire. Make sure
that the connections are tight and firm. Please ensure that the AC cable is adequately
clamped by the metal Strain Relief Clamp (11). Please use the following type designation of
AC cord: "SE, SEoo, ST, STo, SJ, SJEoo, SJT, or SJTo."
Grounding to earth or to other designated ground
for safety, ground the metal chassis of the inverter to the Earth Ground or to the other
designated ground (for example, in a mobile RV, the metal frame of the RV is normally des-
ignated as the negative DC ground). An equipment grounding Lug (7) has been provided
for grounding the metal chassis of the inverter to the appropriate ground.
When using the inverter in a building, connect a 10 mm 2 or AWG #8 insulated stranded
copper wire from the above equipment grounding lug to the Earth Ground connection ( a
connection that connects to the Ground Rod or to the water pipe or to another connection
that is solidly bonded to the Earth Ground ). The connections must be tight against bare
metal. Use star washers to penetrate paint and corrosion.
When using the inverter in a mobile RV, connect a 10 mm 2 or AWG #8 insulated stranded
copper wire from the above equipment grounding lug to the appropriate ground bus of
the RV (usually the vehicle chassis or a dedicated DC ground bus). The connections must be
tight against bare metal. Use star washers to penetrate paint and corrosion.
optional Wired Remote control
An optional Wired Remote Control Model No. RC-200 (with 16.5 ft. / 5 metre cable), is avail-
able for switching oN and switching off. The remote has LCD display showing AC output V,
A, Hz, W, VA and Power factor. It also has LED indications similar to the indications on the
front panel (2, 3, 4 in fig. 6.1). Read Remote Control Manual for details.
Powering on the Loads
After the inverter is switched on, it takes a finite time to become ready to deliver full power.
Hence, always switch on the load(s) after a few seconds of switching on the inverter. Avoid
switching on the inverter with the load already switched on. This may prematurely trigger
the overload protection.
When a load is switched on, it may require initial higher power surge to start. Hence, if mul-
tiple loads are being powered, they should be switched on one by one so that the inverter is
not overloaded by the higher starting surge if all the loads are switched on at once.
