For reasons of EMC, the device should also be grounded via the grounding connection ཱི,
which is connected to the primary input (PE)
. Ensure that this connection is as short as
possible and has a cable cross-section of at least 10 mm². This will ensure that any faults
occurring on the shielding can be dissipated as well as possible.
The grounding connection
ཱི must be electrically connected to the ground potential using a
contact disc. Tighten the screw with a torque of ถ 1.5 Nm.
(b) Flat washer
(d) Contact washer:
To make ground contact, use contact wash-
ers according to the Siemens standard: SN
70093-6-FStflNnnc- 480h, Siemens item no.:
H70093-A60-Z3
