Warning notices

2.4

Be sure to observe this information. Failure to do so may result in personal injury or damage to property!

Installation loca-

tion

Ensure that the machine cabinet is not installed above or in the direct vicinity of water

vessels. There is a risk of electric shock if improperly installed.

Mains connection

Only connect the machine cabinet to a correctly installed 230 V socket or earth cable

which is fused with an upstream 16 A fuse.

Electrical equipment connected to the mains may be damaged during a storm. We

would recommend fitting surge protection in the building to protect against this.

The connection cable must be laid

in a way it won’t represent a tripping hazard.

Explosive atmos-

pheres

The control unit must not be fitted or activated in environments with potential explo-

sive atmospheres or in places where there are flammable materials. Sparks in such

environments may cause an explosion or fire and this may result in physical injuries

or even death.

Interferences

The control unit may cause medical equipment to malfunction. This device should

therefore not be used in close proximity to medical equipment.

Damage

The control unit must not be operated if the housing or cable insulation is damaged or

crushed.

Service work

Service work on the machine cabinet may only be undertaken by authorised special-

ists / electricians.

Voltage supply

The power supply must be ensured at all times. Please ensure that the fuse on the

control cabinet is sufficient (16 A). Additional electrical fixtures on the same fuse may

disrupt operation.
