ONNECTIONS
All field wiring is connected via the 3-tier screw terminal block (TB1). To obtain best results from this device
the use of shielded cables is strongly recommended and in the case of cable lengths greater than 30m
shielded cables are required to ensure proper function of the HPTB. See Figure 3 below for specific device
connections.
Pepperl+Fuchs recommends that all shield drain wires be connected from as close to TB1 as possible to
the nearest grounding point and this point be linked to earth by as short a route as possible.
