4. 2. 4 Safety regulations
Be sure to observe the following safety regulations before carrying out work inside
a basic system:
Warning
Components, interface cards or system modules can be damaged by
electrical voltage.
Always disconnect the system from the power supply before removing
the housing cover.
Warning
Components can be damaged by electrostatic discharge when touched.
Always touch the earthed metal case of the basic system before carrying
out work inside the housing. This also applies to interface cards and sys-
tem modules that are no longer packed inside the ESD protective wrap-
ping.
4. 2. 5 Wall mounting
There are two possibilities for wall mounting. In the first variant the front panel
faces right (see
Fig. 16 ); in the second, it faces downwards (see Fig. 17 ). The wall-
mounting option chosen will depend on the way the cables are routed. The LED
display remains visible whatever the mounting position, even when the cable
cover is fitted.
Warning
A wall-mounting option in which the front panel faces upwards or to the
right is not permitted. Inadequate heat dissipation can damage the sys-
tem.
4. 2. 5. 1 Minimum distances
To ensure adequate heat dissipation, minimum distances need to be maintained
with other objects such as cable ducts, cabinets or mobile objects. Maintaining
minimum distances also allows the installation of the cable cover and the possibil-
ity of suspending the system into and out of the wall-mounted screws.
The two diagrams below illustrate the two wall-mounting possibilities.
