4 Function description
}The backplane is used for communication between the head module and the electronic
modules and forms the carrier unit for the electronic modules. Communication also
takes place when some slots on a backplane are unoccupied.
}The module can be used to interrupt the periphery supply and to form new supply
groups.
4.1 Supply groups
For potential isolation, the supply (Periphery Supply) of the upstream (left-hand) modules
on the backplane is interrupted and is refreshed for the downstream (right-hand) modules
at a supply voltage module.
Supply group 1 Supply group 2 Supply group 3

Interrupting the electrical connection to the left-hand module
1. Use a screwdriver to move
the yellow contact block into
the central position
2. Use a screwdriver to press
the yellow contact block down-
wards. The yellow contact
block is countersunk.
3. Use a screwdriver to move
the yellow contact block into
the position shown.

Restoring the electrical connection to the left-hand module
Prerequisite:
Supply voltage is switched off. Backplanes may only be inserted or removed when the sup-
ply voltage is switched off.
The backplane is uninstalled from the mounting rail.
1. The yellow contact block is
countersunk. Use a screwdriver
to move the yellow contact block
into the central position.
2. Turn the backplane to the
rear. Use a screwdriver to press
the yellow contact block back
into its start position.
3. Move the yellow contact block
into the position shown. The
electrical connection to the left-
hand slot is now established.

5 Installation
CAUTION!
Risk of material damage
Backplanes may only be inserted or removed when the supply voltage is
switched off.
Switch off the supply voltage before inserting or removing the backplane.
INFORMATION
Check whether shielded cable should be connected.
If shielding is required you will need a shield connection element (not sup-
plied with the device; see chapter entitled Accessories [ 19]). The
shield connection element must be attached in the first installation step (see
Install shield connection element (optional) [ 16]).
5.1 General installation guidelines
NOTICE
Damage due to electrostatic discharge!
Electrostatic discharge can damage components. Ensure against discharge
before touching the product, e.g. by touching an earthed, conductive sur-
face or by wearing an earthed armband.

1. Insert the backplane on to the mounting
rail. Leave enough distance [X] to the left to
enable the head module to be installed. This
distance will depend on the width of the
head module.
The mounting rail interlock must be in the
open position, to the left.
2. Turn the mounting rail interlock to the
right to lock the backplane on to the mount-
ing rail.

5.4 Install protective plate
NOTICE
Damage due to electrostatic discharge!
Electrostatic discharge can damage components. Make sure that the yellow
cover plate is fitted at the end of the backplane block. The yellow cover
plate is an integral part of the head module.

Installation

1. Remove the yellow cover
plate from the head module.
2. Attach the yellow ESD cover
plate to the last backplane.
5.5 Install shield connection element (optional)
A shield connection element can be installed on the 4x backplane as an option. The shield
connection element generates the direct contact to the mounting rail. The shield connection
element is not supplied with the device; see chapter entitled Accessories [ 19]).
1. Attach the shield connection
element to the rear of the
backplane and push it in the
direction of the arrow that is
shown until it clicks in place at
the locations indicated by the
arrows.
