Protective Earth Connection
The terminal must be grounded to protective earth via the M3 threaded bolts and the blade
terminal, as well as to the control cabinet over a broad surface via the mount. It is important
to establish a low-Ohm connection to ground to ensure error-free function. The ground con-
nection must be made with the maximum cross section and largest (electrical) surface pos-
sible. The cable length of the ground connection must also be kept as short as possible.
