Guidelines on the Declaration of Conformity

A conformity evaluation has been carried out for the product in terms of the EU Low Voltage Directive 2014/35/EU and the 
Electromagnetic Compatibility (EMC) Directive 2014/30/EU. The Declaration of Conformity is laid out in writing in a separate 
document and can be requested if required.

Guidelines on the EMC Directive (2014/30/EU)

The product cannot be operated independently according to the EMC directive. 
Only after integration of the product into an overall system can this be evaluated in terms of the EMC. 
For electronic equipment, the evaluation has been verified for the individual product in laboratory conditions, but not in the 
overall system.

Guidelines on the Machinery Directive (2006/42/EC)

The product is a component for installation into machines according to the Machinery Directive 2006/42/EC. 
The product can fulfil the specifications for safety-related applications in coordination with other elements. 
The type and scope of the required measures result from the machine risk analysis. 
The product then becomes a machine component and the machine manufacturer assesses the conformity of the safety 
device to the directive. It is forbidden to start use of the product until you have ensured that the machine accords with the 
regulations stated in the directive.

Guidelines on the ATEX Directive

Without a conformity evaluation, this product is not suitable for use in areas where there is a high danger of explosion. For 
application of this product in areas where there is a high danger of explosion, it must be classified and marked according 
to Directive 2014/34/EU.

Safety and Guideline Signs

DANGER

Immediate and impending danger, which can 
lead to severe physical injuries or to death.

CAUTION

Danger of injury to personnel and damage to 
machines.

Guidelines on important points.

General Safety Guidelines

DANGER

Danger of death! Do not touch voltage-carrying 
lines and components.

DANGER

Danger of burns when touching hot surfaces.

CAUTION

•  Danger of device failures caused by short-

circuits and earth short-circuits at the 
terminals

•  Electronic devices cannot be guaranteed fail-

safe.

During the risk assessment required when designing the machine or 
system, the dangers involved must be evaluated and removed by 
taking appropriate protective measures. 
To prevent injury or damage, only professionals and specialists 
are allowed to work on the devices. They must be familiar with the 
dimensioning, transport, installation, initial operation, maintenance 
and disposal according to the relevant standards and regulations.

Before product installation and initial operation, 
please read the Installation and Operational 
Instructions carefully and observe the Safety 
Regulations. Incorrect operation can cause injury 
or damage.

General Safety Guidelines

Only carry out installation, maintenance and 
repairs in a de-energised, disengaged 
state and secure the system against inadvertent 
switch-on.
