■ Technical specifications
1)
These products were built as Class A devices. The use of these devices in
residential areas could result in lead in radio interference. In this case
these may be required to introduce additional interference suppression
measures. The versions 3RF24 ..-1AC55 comply with Class B for residen-
tial, business and commercial applications
2)
If two different conductor cross-sections are connected to one clamping
point, both cross-sections must lie in the range specified. If identical cross-
sections are used, this restriction does not apply.
3)
The screw is not included in the scope of supply.
