Safety information

Required safety precautions before installation work is carried out
Hazardous electrical voltage
The Cabinet Modules are used in industrial high-voltage installations. During operation, this
Cabinet Module contains rotating and live parts. For this reason, there is a risk of severe
injury or significant material damage if the required covers are removed without
authorization, if it is used or operated incorrectly, or if it has not been properly maintained.
You must read and comply with the safety information provided in this Manual.
When carrying out any kind of work on electrical devices, the following five safety rules
must always be observed in accordance with EN 50110-1 and EN 50110-2:
 Disconnect from power supply.
 Protect against reconnection.
 Make sure that the equipment is de-energized.
 Ground and short-circuit.
 Cover or enclose adjacent components that are still live.
Note
Different versions
The Cabinet Modules come in a range of different frame sizes, with each size differing from
the others in several ways. The main differences are:
 The covers used can have different dimensions, and they can be arranged and secured
 The components can be arranged differently within the cabinet units.
 The components can be mounted within the cabinet units using different methods.
These variations result from the different requirements made of the components/equipment
installed in the cabinet units. These differences are intentional and exist for "EMC
optimization" reasons.
