5.1 Installing the unit
Safe converter operation requires that the equipment is mounted and
commissioned by qualified personnel taking into account the warning
information provided in these Operating Instructions.
The general and domestic installation and safety regulations for work
on electrical power equipment (e.g. VDE) must be observed as well as
the professional handling of tools and the use of personal protective
equipment.
Death, severe bodily injury or significant material damage could result if
these instructions are not followed.
When positioning the units, it must be observed that the mains
connection is located at the top section of the unit and the motor
connection at the lower section of the unit.
The units can be mounted flush with each other.
When mounting in switch cabinets, you must leave a clearance at the
top and the bottom of the units for cooling.
Please refer to the dimension drawings on the following pages
regarding these minimum clearances.
When mounting in switch cabinets, the cabinet cooling must be
dimensioned according to the dissipated power. Please refer to the
Technical Data in this regard.
♦
Foreign particles
The units must be protected against the ingress of foreign particles
as otherwise their function and operational safety cannot be
ensured.
♦
Dust, gases, vapors
Equipment rooms must be dry and dust-free. Ambient and cooling
air must not contain any electrically conductive gases, vapors and
dusts which could diminish the functionality. If necessary, filters
should be used or other corrective measures taken.
♦
Cooling air
The ambient climate of the units must not exceed the values of DIN
IEC 721-3-3 class 3K3. For cooling air temperatures of more than
40°C (104°F) and installation altitudes higher than 1000 m, derating
is required.
