ELECTRICAL CONNECTION
To access the terminal block, remove the blind cover (without display). To
do so, loosen the cover locking screw (see figure 2.10) by turning it
clockwise.
Figure 2.11 shows power terminals, ground terminals (one internal and one
external), plus communication terminals, 4-20 mA current return and tests
for standard VVP10 HART. Figure 2.12 shows terminals for digital I/O model
(complete).
To power the equipment, it is recommended to use twisted-pair 22 AWG
cables. Tables 2.1 and 2.2 describe the functions of the terminals for
standard and complete VVP10 HART models, respectively.
