Directives

Regulations

Carry out the power supply connection

and all earthing measures (i.e. RCD cir-

cuit) in accordance with IEC 60364, the

requirements of your local power supply

utility, and VDE or national regulations.

Protect the power cable to the control

unit with an appropriate fuse/MCB.

For oil and gas combustion equipment

over 100 kW, according to the Sample

Combustion Ordinance "FeuVO", an

"emergency shutdown" must be installed

on site outside the installation room. The

national combustion equipment ordi-

nance for your local region must be

observed. For combustion equipment to

EN 50156-1, the "emergency shut-

down" installed on site must comply with

the requirements of EN 50156-1.

Install the "emergency shutdown" out-

side the installation room; it must be able

to separate all non-earthed conductors

simultaneously with a gap of 3 mm at

least.

We additionally recommend installing an

AC/DC-sensitive RCD (RCD class B

) for DC (fault) currents that can occur

with energy-efficient equipment.
