Connect the ground on the rear plate of the device to the protective ground of the
panel. Use at least one M4 screw for the device ground. The cross-sectional area
of the ground wire must be greater than or equal to the cross-sectional area of any
other control conductor connected to the device. Furthermore, the cross-sectional
area of the ground wire must be at least AWG 13.
q
Connect the plug terminals and/or the threaded terminals on the rear side of the de-
vice according to the elementary diagram for the panel.
When using spade lugs or directly connecting wires to threaded terminals, the
screws must be tightened so that the heads are even with the terminal block before
the lugs or wires are inserted.
A ring lug must be centered in the connection chamber so that the screw thread fits
in the hole of the lug.
