[ PRECAUTIONS ]
1.
Do not ground the equipment on gas pipes, water pipes
or lightning rods, or crossground with telephones. Im-
proper grounding could result in electric shock.
WARNING
This equipment can be installed with a Ground-Fault
Circuit Interrupter (GFCI). Although this is a recognized
measure for additional protection, with the grounding
system in North America, a dedicated GFCI is not nec-
essary.
