Power supply
3.1 Safety instructions
For the power supply applies:
n
It is mounted together with your System MICRO modules on a DIN rail. In this case,
the power supply must always be mounted only on the outer edge of your System
MICRO, otherwise the backplane bus is interrupted. The power supply has no con-
nection to the backplane bus.
n
When selecting the mounting location, please note that the power supply is suffi-
ciently cooled during operation.
Below are the precautions to take when using the power supply.
CAUTION!
–
The power supply may only be installed in dry rooms, which are only
accessible by the maintenance engineer!
–
The power supply is not approved for use in potentially explosive
environments (EX zone)!
–
Before you start to work on at the power supply for installation or
maintenance, you have to disconnect it from the main power source,
i.e. the power line is to be switched off (unplug the plug, with perma-
nent connection the associated fuse must be removed)!
–
Only properly qualified electrical staff is allowed to install, connect
and/or modify electrical equipment!
–
Due to the compact design, the contact and fire protection can not be
maintained to ensure sufficient cooling. For this reason, fire protection
must be ensured by the construction of the environment of the
installed power supply unit (e.g. installation in a control cabinet that
complies with the fire protection regulations)!
–
Please adhere to the national rules and regulations of the location
and/or country where the units are installed (installation, safety pre-
cautions, EMC ...).
