3. Physical Layout of the Sima STP-3000
Power flows logically from the rear terminals of the
Sima STP-3000
unit forward to the front panel of the AC output receptacle (or optional junction
box). All indicators, controls, and output connections are conveniently accessed from the front panel (See
Figure 3a
and
Figure 3b
). Their detail
functions are explained in Section 6.1 below. A circulating fan draws cooling-air in from the rear and forces the flow out through vents on the front
panel.
NOTE: It is extremely important to provide adequate airspace around the unit surfaces to allow for convection
cooling as described in Section 5.1 –

REMOVE POWER AT THE SOURCE
BEFORE SERVICING.
BAR GRAPH METERS:
Display battery voltage and current. Current should be in the
GREEN zone ONLY for continuous operation; The inverter will
