Bonding Location
A ground bonding location is provided on the rear of the chassis. An M4 stud is provided. An
outside-toothed lock washer is provided for attaching a ring terminal. A standard ground symbol is
available by each stud.
The following illustration indicates the bonding location on the chassis.
Recommended Terminals
You must use a UL-Approved terminal for the ground connection. A ring terminal with a clearance hole
for #6 (M3.5) stud may be used. For 16 AWG wire, AMP/Tyco 36151 is recommended. This is a
UL-approved ring terminal with a hole for a #6 stud.
Ground Wire Requirements
The ground wire must be sized sufficiently to handle the current of the circuit in case of a single fault.
The size of the ground wire should be equal to the current of the breaker used to protect the circuit. See
Bare conductors must be coated with antioxidant before crimp connections are made. Only copper cables
can be used for grounding purposes.
