tion and are internally connected to the metal chassis of the inverter. The metal chassis
of the inverter is connected to the designated Ground. When the “Schuko” plug (1) of
the power cord of the AC device is plugged into the corresponding “Schuko” receptacle
on the inverter (2 in fig. 8.4 or 5 in figs. 6.1, 6.2 and 6.3), the chassis of the AC device is
automatically connected to the designated Ground through the equipment grounding
conductor that is connected to the spring contacts (2.2, fig 8.4) of the “Schuko” recepta-
cle on the inverter (5 in figs. 6.1, 6.2 and 6.3)
WARninG!
Because the “Schuko” plug (1) can be inserted in either direction into the
Schuko receptacle (2), the “Schuko” connection system is not polarized (i.e. Line
and Neutral could get reversed). Hence, both the current carrying conductors
are isolated from the chassis of the inverter and there is No NEUTRAL. Each of
the 2 female contacts (2.1) of the “Schuko” receptacle will be at an elevated
voltage with respect to the chassis of the inverter as follows and should not be
touched:
- PST-60S: 15 VAC to 214 VAC
- PST-100S: 74 VAC to 151 VAC
- PST-150S: 83 VAC to 146 VAC
- PST-200S: 82 VAC to 149 VAC
Please note that the voltage between the 2 female contacts (2.1) of the
“Schuko” receptacle connected to the 2 internal current carrying conductors
of the inverter will be 230 VAC.
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.
