Fastening The Converter To A Flat Surface; Connecting Converter Cables - Schumacher Electric PC-1000 Owner's Manual

IMPORTANT: This converter uses a
modified sine waveform (diagram A)
which is not quite the same as power
company electricity (diagram B). For the
following devices, we strongly recommend
that you use caution and check the
device's manual to make sure it is
compatible with modified sine waveform.
1. Switch mode power supplies
2. Linear power supplies
3. Class 2 transformers
4. Line filter capacitors
5. Shaded pole motors
6. Fan motors
7. Microwave ovens
8. Fluorescent and high intensity lamps
(with a ballast)
9. Transformer less battery chargers
Using the converter with any of these
devices may cause the device to run
warmer or overheat.

6. FASTENING THE CONVERTER TO A FLAT SURFACE

For your convenience, the converter may
be fastened horizontally to a flat surface.
The area where the converter is to be
fastened must be dry, well-ventilated
and away from any combustible material
or fumes.

7. CONNECTING CONVERTER CABLES

The converter and power source must be
in the OFF mode.
IMPORTANT: Make sure to connect your
converter only to a 12 volt power supply.
To avoid electrical shock, it is necessary
to ground the converter as well as the
device powering it. The converter should
be grounded, using a 16 AWG copper
wire (included).
NOTE: Do not turn on the converter or the
power source until the converter and the
power source are grounded.
TO GROUND THE CONVERTER
1. Turn off and disconnect the converter.
2. Locate the chassis ground screw on
the back of the converter.

IMPORTANT: If you are using the
power converter to operate a battery
charger, monitor the temperature of the
battery charger for about 10 minutes.
If the battery charger becomes
abnormally warm, disconnect it from
the converter immediately.
1. Turn off and disconnect the converter.
2. Place the back of the converter with
the mounting bracket against a flat,
secure surface.
3. Attach the converter, using corrosion-
resistant screws.
3. Remove the outer hex nut and loosen
the second hex nut.
4. Attach the grounding wire's ring
connector to the ground terminal of
the converter.
5. Tighten the hex nut securely. Then,
replace the other hex nut and tighten
it securely.
6. Attach the other end of the wire to a
properly grounded location:
Vehicle: Connect to the chassis, unpainted
frame part, or engine block of the vehicle.
Fixed location: Connect to a ground rod
or other appropriately rated ground.
