. 2 Safety hints
This unit was built and tested in compliance with VDE 0411-1 / EN 61010-1 and was delivered in safe condition.
The unit complies with European guideline 89/336/EWG (EMC) and is provided with CE marking.
The unit was tested before delivery and has passed the tests required by the test schedule. To maintain this condition
and to ensure safe operation, the user must follow the hints and warnings given in this operating manual and operate
this instrument in compliance with the instructions given in this manual.
a
The unit is intended exclusively for use as a measurement and control instrument in technical
installations.
a
Warning
If the unit is damaged to an extent that safe operation seems impossible, the unit must not be taken into
operation.
ELECTRICAL CONNECTIONS
The electrical wiring must conform to local standards (e.g. VDE 0100). The input measurement and control leads must
be kept separate from signal and power supply leads.
Using screened cables is mandatory! The screening must be connected to ground potential.
In the installation of the controller a switch or a circuit-breaker must be used and signified. The switch or cir -
cuit-breaker must be installed near by the controller and the user must have easy access to the controller.
COMMISSIONING
Before instrument switch-on, check that the following information is taken into account:
• Ensure that the supply voltage corresponds to the specifications on the type label.
• All covers required for contact protection must be fitted.
•
If the controller is connected with other units in the same signal loop, check that the equipment in
the output circuit is not affected before switch-on. If necessary, suitable protective measures must
be taken.
• The unit may be operated only in installed condition.
•
Before and during operation, the temperature restrictions specified for controller operation must
be met.
a
Warning
During operation, the ventilation slots of the housing must not be covered.
a
The measurement inputs are designed for measurement of circuits which are not connected directly with
the mains supply (CAT I). The measurement inputs are designed for transient voltage peaks up to 800V
against PE.

SHUT-DOWN
For taking the unit out of operation, disconnect it from all voltage sources and protect it against accidental operation.
If the controller is connected with other equipment in the same signal loop, check that other equipment in the output
circuit is not affected before switch-off. If necessary, suitable protective measures must be taken.
