Safety instructions

General safety and application notes for Lenze controllers



EDS700ACBA EN 4.0

Electrical connection

When working on live controllers, observe the applicable national regulations for the

prevention of accidents (e.g. VBG 4).

The electrical installation must be carried out according to the appropriate regulations

(e.g. cable cross−sections, fuses, PE connection). Additional information can be obtained

from the documentation.

This documentation contains information on installation in compliance with EMC

(shielding, earthing, filter, and cables). These notes must also be observed for CE−marked

controllers. The manufacturer of the system is responsible for compliance with the limit

values demanded by EMC legislation. The controllers must be installed in housings (e.g.

control cabinets) to meet the limit values for radio interferences valid at the site of

installation. The housings must enable an EMC−compliant installation. Observe in

particular that e.g. the control cabinet doors have a circumferential metal connection to

the housing. Reduce housing openings and cutouts to a minimum.

Lenze controllers may cause a DC current in the PE conductor. If a residual current device

(RCD) is used for protection against direct or indirect contact for a controller with

three−phase supply, only a residual current device (RCD) of type B is permissible on the

supply side of the controller. If the controller has a single−phase supply, a residual current

device (RCD) of type A is also permissible. Apart from using a residual current device (RCD),

other protective measures can be taken as well, e.g. electrical isolation by double or

reinforced insulation or isolation from the supply system by means of a transformer.

Operation

If necessary, systems including controllers must be equipped with additional monitoring

and protection devices according to the valid safety regulations (e.g. law on technical

equipment, regulations for the prevention of accidents). The controllers can be adapted to

your application. Please observe the corresponding information given in the

documentation.

After the controller has been disconnected from the supply voltage, all live components

and power terminals must not be touched immediately because capacitors can still be

charged. Please observe the corresponding stickers on the controller.

All protection covers and doors must be shut during operation.

Safety functions

Certain controller versions support safety functions (e.g. "Safe torque off", formerly "Safe

standstill") according to the requirements of the EC Directive 2006/42/EC (Machinery

Directive). The notes on the integrated safety system provided in this documentation must

be observed.

Maintenance and servicing

The controllers do not require any maintenance if the prescribed operating conditions are

observed.
