9. Safety advice

Please read the following safety advice and the assembly chapter 1 before installation

and keep it for future reference.

Proper use

The M2-device is designed for the evaluation and display of sensor signals.

Danger! Careless use or improper operation can result in

personal injury and/or damage to the equipment.

Control of the device

The panel meters are checked before dispatch and sent out in perfect condition. Should

there be any visible damage, we recommend close examination of the packaging. Please

inform the supplier immediately of any damage.

Installation

The M2-device must be installed by a suitably qualified specialist (e.g. with a

qualification in industrial electronics).

Notes on installation

• There must be no magnetic or electric fields in the vicinity of the device, e.g. due to

transformers, mobile phones or electrostatic discharge.

• The fuse rating of the supply voltage should not exceed a value of 6A N.B. fuse.

• Do not install inductive consumers (relays, solenoid valves etc.) near the device and

suppress any interference with the aid of RC spark extinguishing combinations or free-

wheeling diodes.

• Keep input, output and supply lines separate from one another and do not lay them

parallel with each other. Position "go" and "return lines" next to one another. Where

possible use twisted pair. So, you receive best measuring results.

• Screen off and twist sensor lines. Do not lay current-carrying lines in the vicinity. Connect

the screening on one side on a suitable potential equaliser (normally signal ground).

• The device is not suitable for installation in areas where there is a risk of explosion.

• Any electrical connection deviating from the connection diagram can endanger human life

and/or can destroy the equipment.

• The terminal area of the devices is part of the service. Here electrostatic discharge needs

to be avoided. Attention! High voltages can cause dangerous body currents.

• Galvanic insulated potentials within one complex need to be placed on a appropriate point

(normally earth or machines ground). So, a lower disturbance sensibility against impacted

energy can be reached and dangerous potentials, that can occur on long lines or due to

faulty wiring, can be avoided.
