4.1 Electromagnetic compatibility, EMC
Limit values This product meets the EMC requirements according to the standard
IEC 61800-3 if the measures described in this manual are implemented
during installation.
If the selected composition is not designed for category C1, note the fol-
lowing:
An EMC-compliant design is required to meet the specified limit values.
Note the following requirements:
Control cabinet design
@ WARNING
SIGNAL AND DEVICE INTERFERENCE
Signal interference can cause unexpected responses of device.
• Install the wiring in accordance with the EMC requirements.
• Verify compliance with the EMC requirements.
Failure to follow these instructions can result in death, serious
injury or equipment damage.
@ WARNING
HIGH-FREQUENCY INTERFERENCE
In a residential environment this product may cause high-frequency
interference that requires interference suppression.
Failure to follow these instructions can result in death or serious
injury.
EMC measures Objective
Use galvanised or chrome-plated mounting plates,
make large contact surface connections for metal
parts, remove paint from contact surfaces
Good conductivity due
to two-dimensional con-
tacts
Ground the control cabinet, the control cabinet door
and the mounting plate with ground straps or
ground wires. The conductor cross section must be
at least 10 mm
2
(AWG 6).
Reduces emissions.
Fit switching devices such as power contactors,
relays or solenoid valves with interference suppres-
sion units or arc suppressors (for example, diodes,
varistors, RC circuits).
Reduces mutual interfer-
ence
Install power components and control components
separately.
