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
designated as the negative DC ground). for PST-60 and PST-100. An equipment ground-
ing bolt with a wing nut (7) has been provided for grounding the metal chassis of the
inverter to the appropriate ground. for PST-150 and PST-200, grounding lug (7) has been
provided.
When using the inverter in a building, connect a 10 mm 2 or AWG #8 insulated stranded
copper wire from the above equipment grounding bolt to the Earth Ground connec-
tion ( 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 bolt 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.
seCtIOn 8 | Installation
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
multiple 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.
Switching the inverter on/oFF
Before switching on the inverter, check that all the AC loads have been switched off. The
oN/off switch (1) on the front panel of the inverter is used to switch on and switch off
the inverter. This switch operates a low power control circuitry, which in turn controls all
the high power circuitry.
