A Warning and Safety Instructions

1 General information

Service and repair work should only be carried out by suitably qualified persons in accordance with all appropriate local and national safety regulations.

Servicing, modification, testing and maintenance of electrical appliances should only be carried out in accordance with all appropriate legal requirements, accident prevention regulations and valid standards.

All regulations of the appropriate utility supply companies and standards relating to safety (not limited to electrical safety) are to be complied with.

Before any service work is commenced, the machine must be disconnected from the mains.

Even with the machine switched off, mains power may be applied to some components.

A general visual check should always be carried out.

Descriptive Technical Documentation

A-2 DTD no. 521-7135

2 Risk of injury due to sharp edges

There may be a risk of injury due to sharp edges.

Protective gloves should be worn and the edge protection, Mat. no. 05057680, should be used.

Descriptive Technical Documentation

DTD no. 521-7135 A-3

3 Electrical connection via plug connector

It is always recommended to make electrical connection via a plug and socket so that electrical safety checks, e.g. during repair or service work, can be carried out easily.

The socket must be accessible after machine installation. This also applies even if an on-site mains switch is also already provided.

For models with a total connected load greater than 9 kW, an additional on-site mains switch must also be provided.

Electrical connection must be carried out in accordance with all appropriate legal requirements, accident prevention regulations and valid standards.

Descriptive Technical Documentation

A-4 DTD no. 521-7135

4 Touch current measurement

Note

On machines with an earth connection, touch current leakage measurements should be carried out on all accessible conductive parts that are not connected to the earth.

Warning!

Touch current measurement should only be carried out after the earth connection of the unit under test has been checked and found to be satisfactory!

Dangerous voltages may exist on defective machines as well as on accessible conductive parts that are not connected to earth!

Note

Touch current measurement should be carried out on the following accessible conductive parts:

• None.
