Step 10: Connecting the Remote Shutdown
Some installations may require remote shutdown capability. This feature
enables you disable all circuitry in the inverter•charger and remove all power
from the display panel using a remote shutdown switch (e.g. the ignition
switch in a vehicle). This also removes all power (inverter and shorepower)
from the AC loads.
The remote shutdown signal (RS+/RS–) requires a source of 5–18Vdc, which
is capable of supplying 5–18mA, to enable the inverter•charger. This power
source must be limited to Class 2 levels by an approved 1A fuse. The power
source will often be one of the existing system batteries: the vehicle starting
battery or the inverter•charger battery. In this case, the 1A fuse must be
located in the positive (+) side of the circuit, as close as possible to the power
source.
Note that the remote shutdown feature will only function when the ON/OFF/
REM switch is set to REM.
Materials Required
You need two high quality 26AWG, 4-conductor telephone cables with
connectors attached (one 10 feet maximum; one 100 feet maximum), one 1:2
phone line splitter, and a 1A fuse and in-line fuseholder. In addition, you
might require a single pole, single throw switch (or alternatively, you can use
a vehicle ignition-switched circuit). You can obtain these from local hardware,
electronics, and automotive stores.
Installation Steps
See Figure 18 and Figure 19.

To connect the remote shutdown feature
1. Select one of the two cables and cut it at a convenient location for
connecting to your Remote Shutdown Switch.
2. See Figure 18 to identify the RS+ and RS– wires.
3. Insulate the two middle wires so they don’t short.
4. Connect RS+ to the positive of a switched, fused voltage source of 5–18V.
5. Connect the RS– to the return of this voltage source.
WARNING: Shock Hazard
This step should only be completed by qualified installers or
technicians who have a knowledge of DC circuits.
Connect only to an isolated Class 2 extra-low voltage power source as
described below.
