Connecting Cables
Installation
WARNING You may observe a spark when making
the connection because current can flow to charge
the capacitors in the inverter. Do not make this
connection in the presence of flammable fumes.
Explosion or fire may result. Thoroughly ventilate
the battery compartment before making this
connection.
3. Connect cable to the power source:
a. Connect the cable from the Negative (Black)
Terminal of inverter to the Negative Terminal
of the power source. Make a secure connection.
b. Connect the cable from the Positive (Red) Terminal
of the inverter to the Positive Terminal of the power
source (the battery's main fuse or the battery
selector switch, if you are using one). Make a
secure connection.
You might observe a spark when you make this connection
since current can flow to charge capacitors in the inverter.
All power connections to your Cobra inverter must
be Positive to Positive and Negative to Negative.
