General Advice
•
DO NOT excessively bend the cables of the NSM 400. Allow a minimum bending radius of 80 mm for all
cables.
•
Provide strain relief for all connectors to prevent the cables, plugs or sockets from breaking when moved
or bent.
•
Avoid unnecessarily long and unfixed cables to prevent fluttering caused by strong winds.
•
It is absolutely vital to install all cables or protective caps for connectors J1, J2 and J3 to
ensure waterproofing according to IP 67 class!
