Installation and Connection
Grounding
The housing must be carefully grounded. Connect a ground cable
(protective earth, 4 to 6 mm
2
[AWG 11‒9], tightening torque 1.7 Nm
[15
lb⋅in
]) to the housing, using the screw that is marked with the ground
symbol (at the rear side of the device).
Moreover, the power supply card needs a separate ground connection
(functional earth, min. 2.5 mm
2
[≤ AWG 13], tightening torque 0,56 ‒
0,79 Nm [5‒7
lb⋅in
]). See the “Terminal Marking” diagram in Section “DI-4
X – Power Supply and Digital Inputs” to check for the correct terminal.
All grounding connections (i. e. protective and functional earth) must be
low-inductance, i. e. as short as possible, and national standards – if
applicable – must be followed.
The devices are very sensitive to electro-static discharges.
