7 Technical data

DANGER Danger if the relevant regula-

tions for electrical installations are not ob-

served.

Observe the safety rules of electrical engineering.

Before taking off covers and before installing the

electrics, shut down all supply circuits, switch off

mains fuse, check that no voltage is present, se-

cure against being accidentally switched back on

and position a visible warning sign.

Only connect the unit to a permanent electrical

installation. Select cable type and cross-section

in accordance with DIN VDE 0298-4 → Technical

data.

A mains isolation device with contact openings of

at least 3 mm at each pole is mandatory. Make

connections according to wiring diagram.

The unit may only be operated using the voltage

and frequency shown on the rating plate. Con-

nect PE conductor and check the connection.

Check protective-conductor opening on housing

(VDE 0100-600, VDE 0105-100).

Only operate the unit when it is completely in-

stalled.

Modifications and alterations are not permitted

and release the manufacturer from any guaran-

tee obligations and liability.

Do not put a damaged unit into operation and do

not allow it to be operated until repaired.

The degree of protection stated on the rating

plate is only guaranteed if installation is under-

taken correctly and if the connection cable is cor-

rectly guided into the housing.

CAUTION Exercise caution when hand-

ling packaging materials.

Store packaging material out of the reach of chil-

dren (risk of suffocation due to swallowing).

Installation instructions

• Only install unit on a dry, flat surface. Do not

distort housing. Any installation position can be

selected.

• Select installation location outside of traffic

area. Protect unit from direct sunlight. Ensure

sufficient heat dissipation.

• When connecting several motors, the total cur-

rent must not exceed the rated current of the

motor protection device, especially in the case

of voltage regulation.

Installation

1. Loosen both of the housing cover screws and

remove the housing cover.

2. Break out cable lead-throughs at the predeter-

mined knockout points in the housing, accord-

ing to the number of cables, and insert cable

grommets. Insert the grommets so that they fit

tightly against the housing and around con-

nection cable cables.
