Mounting
3.1 Installation
1. The digital display shall not be installed near to con-
tactors or motor starters.
2. We recommend the use of wire end ferrules in order
to avoid short-circuits between adjacent terminals.
3. In order to keep the interferences at the measuring
input as low as possible, the signal and power sup-
ply wires must be routed separately.
4. Use shieded cables for all signal/probe wirings and
avoid routing the signal/probe wirings parallel to
each other. The shield shall only be grounded at one
point in order to avoid ground loops.
