4.3 Test Loads
Use only equipment rated for 110 - 120 volt,
60 Hz AC operation that has a power
consumption of 500 watts or less. We
recommend that you start with a relatively
low power load, such as a 100 watt lamp,
to verify your test set-up before trying high
power loads.
4.4 Connections
Follow the connection sequence described
below:
STEP 1 - Ensure the ON/OFF switch on
the Portawattz 3000 is in the
OFF position. If the power
source is a DC power supply, switch it off as well.
STEP 2 - Connect the DC cables to the power input
terminals on the rear panel of the Portawattz 3000.
The Red terminal is positive (+) and the Black
terminal is negative (-). Tighten the wire
connections securely. (see figure 4).
STEP 3- Connect the cable from the negative (Black)
terminal of the Portawattz 3000 to the negative
terminal of the power source (battery or power
supply). Make a secure connection.
