Installation

Electrostatic sensitive devices are protected against destruction by electrostatic charge by means
of protective structures at the inputs and outputs. In unfavourable cases, however, plastic floor co-
verings, non-conductive work surfaces, or clothing containing artificial fibres can result in such high
charges that electrostatic sensitive devices can be damaged or even destroyed despite the
protective networks mentioned. If a device is damaged its reliability decreases drastically, al-
though it may be a long time before the effects of the damage are noticeable.
In order to ensure that electrostatic charges are eliminated harmless when working on the system
you must observe the following points without fail:
1. Before carrying out any work on the
system ground yourself with a wrist strap.
3. Only transport modules in suitable pro-
tective bags.
The following points must also be observed during installation:
1. Before installing the device the ground-
ing wire must first be laid and connected to
ground potential.
3. Use shoe grounding strips.

CAUTION !
Electrostatic sensitive devices
DANGER!
!
The device has to be installed in a locked room, with admission for com-
missioning personal only. It must be excluded that other persons except
the commissioning personal has access to this equipment.
ATTENTION!
Sufficient cooling has to be provided!
Warning!
There is a risk of electrostatic discharge up until the grounding wire has
been connected even if you are wearing a wrist strap. If possible you
should therefore not touch modules and wiring before then.
When dismantling the system the grounding wire must not be discon-
nected until all work has been completed.

2. When working on modules always place
them on a grounded, conductive surface
2. Connect the grounding wire immediately
after installing the device or setting up the
cabinet.
