Physical Layout of the Sima STP-3000, AC Panel

3. Physical Layout of the Sima STP-3000

Power flows logically from the rear terminals of the Sima STP-3000unit 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 – Where To Install.

A. AC PANEL

OVERLOAD INDICATOR:

Lights when inverter shuts down because of severe overload. Turn inverter off. Remove cause of overload, and turn inverter on to reset .

ON/OFF SWITCH:

Leave in OFF position during installation

CAUTION! THIS IS NOT A DISCONNECT SWITCH.

REMOVE POWER AT THE SOURCE BEFORE SERVICING.

OVER TEMP INDICATOR: Inverter is shut down while indicator is ON. Inverter will restart automatically.

Indicator lamp and alarm will turn off when the inverter cools. Lights and alarm alerts when inverter protects itself against OVERHEATING.

BAR GRAPH METERS:

Display battery voltage and current. Current should be in the GREEN zone ONLY for continuous operation; The inverter will operate for several minutes when the current in the Yellow zone: operation with battery voltage or current in the red zone of the meter will result in protective shutdown of the inverter.

Ventilation Opening

DO NOT OBSTRUCT – Allow at least 4 inch (100 mm) clearance for air flow.

RED: Positive “+”

CAUTION: Reverse polarity will open internal fuses and MAY damage the inverter permanently

BLACK: Negative “-”

CHASSIS GROUND LUG.

WARNING: Operation of the inverter without a proper ground connection may result in an electrical safety hazard
