Note!
¹)
If the cable length exceeds 50 m, additional loads must not be connected to the
status inputs (refer to «Power supply for the LMV5… system»)!
Above a certain cable length, the actuators must be powered by a separate transformer
installed near the actuators.
The cross-sectional areas of the mains power lines (L, N, PE) and, if required, the
safety loop (safety limit thermostat, water shortage, etc.) must be sized for nominal cur-
rents according to the selected external primary fuse. The cross-sectional areas of the
other cables must be sized in accordance with the internal unit fuse (max. 6.3 AT).
Min. cross-sectional area
0.75 mm²
(single- or multi-core to VDE 0100)
Cable insulation must meet the relevant temperature requirements and conform to the
environmental conditions. The CAN (bus) cables have been specified by Siemens and
can be ordered as accessory items. Other cables must not be used. If this is not
observed, the EMC characteristics of the LMV5... system will be unpredict-
able!
