Cabling
It is essential to separate the power supply cables from the signal cables.
When facing the rear of the rack (as the device is connected via the rear
panel), the power supply cables must be guided to the right of the chassis
and the signal cables to the left.
EMC Ground
The EMC connection is required to ensure ground equipotentiality
between the different devices in the technical center (only one
connection is required per device).
Each Encoder side panel features a tapped hole to connect a bonding
strip. The bonding strip can be fixed either on one side of the chassis
(right or left side) or on the rear of the chassis (left side).
„
Fixing the bonding strip on the back of the chassis. The bonding strip
is fixed using an M4 nut (provided with the product). It must have a
6mm² cross-section and be under 500mm in length.
„ Fixing the bonding strip on the side of the chassis. The bonding strip
is fixed using an M4 screw whose length depends on the bonding strip
type (no more than 15 mm of the screw must be inserted into the
Encoder). The bonding strip must have a 6 mm² cross-section and be
under 500 mm in length.
The rack EMC DC bus (to which the ViBE EM4000 EMC strip is connected)
must be connected to the rack ground pin. This pin is also connected to
the safety ground.
