Power Drive 1500 - Manual (Page 5)

Connect the Power Cables to the Inverter:
Connect cable to the Power Input Terminals on input end of the inverter.
The red terminal is positive (+) and the black terminal is negative (-).
Unscrew the terminal on the inverter and install the appropriate color (black
to black and red to red) ring-terminal of the cables and tighten the screws to
clamp the wires securely.
NOTE: It is a good idea to check and tighten these screws from time to time.
They can become loose by vibrations or thermal cycling. Loose connectors
result in excessive voltage drop and may cause overheated wires and melted
insulation.
Connect the Power Cables to the Battery:
1. Connect the cable from the Negative Terminal (Black) of inverter to the
Negative Terminal of the battery.
2. Connect the cable from the Positive Terminal (Red) of the inverter to the
Positive Terminal of the battery. You might observe a spark when you make
this connection since current can flow to charge capacitors in the inverter.
CAUTION
: Reversing the polarity of these cables (positive to negative) will
result in damage to the RPPD1500 and will void the warranty.
3. The inverter is now ready to deliver AC power to your loads. Press the
Power Button to on. If several loads are to be operated by the inverter, turn
them on separately, after the inverter has been turned on. This will ensure
that the inverter does not have to deliver the starting currents required for
all the loads at once.
CAUTION:
Connect the RPPD1500 to batteries with a normal output of 12-volts DC only.
6-volt batteries do not supply enough voltage, and a 24-volt battery supplies
too much voltage and will damage the RPPD1500. Never work on the AC
wiring without first physically disconnecting the DC connections.
CAUTION:
Never disconnect the DC cables from the inverter without first disconnecting
the cables from the battery or potentially lethal electricity will be left exposed.
NOTE: The Power Button turns the control circuit in the inverter on and off. It
does not disconnect power from the inverter. When the button is in the off
position, the inverter draws no current from the battery. When it’s in the on
