Frequently Asked Questions
Where should the Simplatron controller be installed?
Ensure adequate ventilation; install the unit vertically with terminals pointing downwards.
What specific precautions are needed when connecting control cables?
Control cables must be shielded, and one side of the shielding must be connected to the protective conductor on the unit.
Can I operate the device using armature voltage feedback?
The control electronics are not potential-free in the 'armature voltage control with 1 x R compensation' mode.
What type of fuses must be used for replacement?
Defective fuses must only be replaced by the prescribed type.
