Regulations
Insofar as the machinery corresponds to the machinery directive
89/392/EEC and the configuration meets the EMC test conditions
specified by BERGER LAHR, conformity with the machinery
directive is hereby certified.
Machinery directive
In a configuration which meets the EMC test conditions specified
by BERGER LAHR, conformity with the following standards
can be certified in accordance with the EMC directive 89/336/EEC:
EMC directive
Radio interference suppression
according to EN 50081-2: 1993
(when using a mains filter, see Accessories)
Static discharge
according to EN 60801-2: 1993, class 4
Burst
according to IEC 801-4: 1988, class 4
–
Use a BERGER LAHR motor lead.
Length of motor lead is 10 m.
BERGER LAHR
EMC test requirements
–
Insert a BERGER LAHR mains filter into the mains supply line.
–
Install the device into the control cabinet.
–
Use BERGER LAHR signal cables and wire them according
to the documentation.
–
Run signal, mains and motor cables separately (non-parallel) and
ensure a large surface area contact between the cable shield and
ground on both ends.
–
Install the mains filter directly at the device. If this is not possible, use
a shielded connection line (1 m max.) between filter and device.
–
Ensure a large surface area contact between filter, device and
ground (mount on a grounded metal plate or on control cabinet
rear panel, or use a ground strap).
Pursuant to the low-voltage equipment directive 73/23/EEC, the
products are in conformity with the following standards:
Low-voltage equipment directive
