CAUTION
Power supply must be turned off before connecting control inputs and outputs. Non-compliance can
destroy the device.
NOTE
In order to minimize electromagnetic faults and achieve good signal quality, connect the shield of
the cable is to be connected to ground potential properly, i.e. with good conductivity, on both si-
des.
