2.7 Inverter Warning Label
The warning label (Figure 2-7) is provided to inform all personnel
that an inverter is installed in your electrical system. Af
fi
x this
label in a clearly visible location at the electrical panel that is being
powered by the inverter. This is necessary because it might be
falsely assumed that the panel is no longer “hot” after AC power has
been shut off—when in fact power may actually still be available due
to the inverter automatically powering the panel.
2.6 GFCI
Breakers
When installing a MMSA1012 inverter in an ambulance’s wiring
system, a ground fault circuit interruption breaker (GFCI) may be
installed to protect some branch circuits powered by the inverter.
In compliance with UL standards, Sensata has tested the following
GFCI’s and has found that they function properly when connected
to the inverter’s AC output (there are others on the market that
will work as well):
Shock Sentry
TM
#VGF15W
,
Leviton Smart Lock
#7899
, or
Hubbel #GF520EMBKA
.
WARNING
: Risk of electric shock. Use only ground-fault
circuit interrupters (receptacles or circuit breakers) that are
compatible with your MMSA inverter. Some types may fail to
operate properly when connected to this inverter equipment.
WARNING
: Ground Fault Circuit Interrupters (GFCIs) shall
be installed in the recreational vehicle’s wiring system to
protect all branch circuits.
Figure 2-7, Warning Label
This electrical system is equipped with an
Automatic Generator Starting (AGS) device and/
or an inverter. Disconnect all AC and DC power
to the AGS and/or inverter before performing any
service to the electrical system. Failure to do so
can result in shock causing serious injury or death.
