CAUTION!
Reverse polarity connection (positive to negative) will blow the fuses in the
Portawattz 3000 and may permanently damage the unit. Damage caused by
reverse polarity connection is not covered by your warranty.
WARNING!
You may observe a spark when you make the following connection since current
may flow to charge capacitors in the Portawattz 3000. Do not make this
connection in the presence of flammable fumes. Explosion or fire may result.
STEP 4 - Before proceeding further, carefully check that the
cable you have just attached connects the
negative terminal of the Portawattz 3000 to the
negative output terminal of the power source.
Power connections to the Portawattz 3000 must
be positive to positive and negative to negative.
STEP 5 - Connect the cable from the positive (Red terminal
of the Portawattz 3000 to the positive terminal of
the power source. Make a secure connection.
STEP 6 - If you are using a DC power supply as the power
source, switch it on. Set the ON/OFF switch on
the Portawattz 3000 to the ON position. Check
the meters and indicators on the front panel of
the Portawattz 3000. The battery voltage indicator
should indicate 11 to 14 volts, depending on the
voltage of the power source. If it does not, check
your power source and the connections to the
Portawattz 3000. The other indicators should be
off.
STEP 7 - Set the Portawattz 3000 ON/OFF switch to the OFF
position. The indicator lights may blink and the
internal alarm may sound momentarily. This is
normal. Plug in the test load now, but make sure
that it is first switched off.
STEP 8 - Set the Portawattz 3000 ON/OFF switch to the ON
position and turn the test load on. The Portawattz
3000 should supply power to the load. If it does
not, refer to the troubleshooting section of this
manual. If you plan to measure the output voltage
of the Portawattz 3000, refer to Section 2.2 of this
manual.
