Power modules
10.1 Safety instructions
Intended use of the power modules
The power modules are designed and manufactured:
for installation together with Cube20S system components on a mounting
rail,
for installation in a control cabinet with sufficient ventilation,
for industrial use.
Safety instructions for power modules
Power modules must exclusively be installed in areas which are only ac-
cessible to the maintenance personnel!
Power modules are not approved for use in hazardous areas (EX zone)!
De-energize the power modules prior to starting installation and mainte-
nance work, i.e., prior to starting work on a power supply or a supply line,
de-energize the voltage supply (pull the power plug or, in case of a perma-
nent connection, disconnect the respective fuse)!
Electrical connection and modifications must be performed by trained
electricians only!
Due to the compact design and in order to guarantee sufficient cooling,
touch and fire protection cannot be complied with. For this reason, fire pro-
tection must be guaranteed through the design of the environment of the
integrated power supply unit (e.g. by installation in a control cabinet that
fulfils the fire protection regulations)!
Observe the national regulations and directives in the country where the
device is used (installation, protective measures, EMC, ...).
