4.1 General information
Mount the module with 2 screws (M6x25 / 30) for LioN-R and 2 screws
(M4x25/30) for LioN-P on a level surface. The torque required here is 1 Nm.
Use washers for all fastening methods as per DIN 125. For the mounting
holes, use a distance of 237.3 to 239.7 mm for the LioN-R modules, a
distance of 190.3 to 191.8 mm for LioN-P modules with 7/8"
connector/socket, and a distance of 196.8 to 198.3 mm for LioN-P modules
with M12 power L-coded.
Note
The modules have a ground connection with an M4 thread for the
conduction of interference currents and the EMC immunity. This is labeled
with the symbol for the ground and the designation "XE"
Note
Use a low-impedance connection to connect the module to the reference
ground. When using a grounded mounting surface, you can make the
connection directly via the fixing screws.
Note
If the mounting surface not grounded, use a ground strap or a suitable PE
line. Use an M4 screw to connect the ground strap or the PE line to the
ground point and if possible put a washer and a toothed washer below the
fixing screw.
