4.4 Ground connection (Figure 2)
Minimize noise by connecting the shield and/or the connector housing and/or
the enclosure to ground. Make sure that ground is not affected by noise. The
connection point to ground can be situated both on the device side and on
user’s side. The best solution to minimize the interference must be carried out by
the user. You are advised to provide the ground connection as close as possible
to the unit. We suggest using the ground point provided in the connection cap
(see Figure 2, use one TCEI M3 x 6 cylindrical head screw with two tooth lock
washers).
