Note
Ring cable lug connection system
The procedure for mounting the overload relays with ring cable lug connection system is
similar to that for mounting with screw-type connection system.
Mounting on a mounting plate (sizes S00 and S0)
Screw mounting on a mounting plate is an alternative option to DIN rail mounting. For screw
mounting, the contactor first has to be fastened with screws and then the overload relay
mounted on the top of the contactor as shown in the figures.
