Installation and Connection
Grounding
The housing must be carefully grounded. Connect a ground cable (4 to 6
mm
2
(AWG 12-10) / 1,7 Nm [15 In-lb]) to the housing, using the screw, which
is marked with the ground symbol (at the rear side of the device).
The power supply card needs a separate ground connection (2.5 mm
2
(AWG 14) at terminal X1 (0.56-0.79 Nm [5-7 In-lb]).
The devices are very sensitive to electro-static discharges.
