Cable connection via the PG gland

The connection between AED9101D and other devices

can only be made via a connecting cable with a shield

grounded on both sides and metal connectors (or a

metalized connector housing). Bring the screen extens-

ively into contact on both sides at the PG gland and at

the connector housing. If the device cannot be connected

by a metal connector, you must lay the cable shield

extensively to ground and housing ground, using a shiel-

ded terminal, for example. Also see

Note

With longer cables (over 30m, only possible with RS‐422
and RS‐485), there is a risk that the individual bus nodes
will have different ground potentials. In this case, a sep
arate cable can be used to establish potential equaliza
tion between the bus nodes.

A flexible cable with a conductor cross-section of at least

10mm

2

is the best choice for potential equalization.
