Before connecting or disconnecting ground or power wires to the chassis, ensure that power is removed from the
DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC
circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF
position. Use a voltmeter to test for 0 (zero) voltage at the power terminals on the chassis.
