4. Installation instructions

WARNING!

- Danger of life through mains voltage!

Therefore, the space designed for installation must be disconnected from the
supply and sufficiently protected against accidental or unauthorized reclosing
prior to installation.

CAUTION!

- Danger of life and of damage to property through insufficient protection class!

The protection class of the power supply modules is IP 00. The modules must
be installed in a switch cabinet which must at least comply with protection class
IP 54 (cf. also ”Technical Data” Section).

- Danger of injury and of damage to property through incorrect installation!

The units, and especially the operating elements, must be installed so as to be
sufficiently protected against unintentional operation or contact.

- Danger of injury and of damage to property when operating the units outside a

switch cabinet!
The units are designed to be installed in housings or switch cabinets and may
only be operated in such housings or cabinets with the door closed!

- Danger of injury at sharp metal edges!

You should therefore wear protective gloves.

- Danger of damage to property through short-circuits!

When drilling or sawing out openings within switch cabinets, metal burr may get
inside modules that have already been installed. It is also possible that water
may emerge during the installation of the cooling water lines and may enter the
modules.
The possibility of short-circuits and a destruction of the units cannot be entirely
ruled out.
Therefore, the modules should be well partitioned prior to any additional work!
No liability is accepted in the event of non-compliance.

- Damages to property through leaks in the cooling water circuit!

A leak in the cooling water circuit may cause damages to adjacent components
through emerging cooling water. Therefore you should install water-cooled mo-
dules so as to sufficiently protect other units in the switch cabinet against lea-
king cooling water.

NOTE

- Connecting lines and signal lines must be laid so as to avoid negative effects on

the function of the units through capacitive or inductive interference!

- A clearance of min. 100 mm must be available above and below the power sup-

ply modules. If these clearances are not maintained, there is a risk of heat accu-
mulation which may lead to a failure of the unit.
