Important notes
:
• The si628 P does not require ground connec-
tion (terminal 1).
• In environments with interference problems it
is recommended to connect the instrument to
ground in terminal 1.
It is also recommended to use shielding cable,
both for the electrode signal (triaxial cable) and
the temperature probe.
The external shield of the triaxial cable and the
probe cable must be connected to terminal 14.
• If the temperature probe has a 2-wire cable
instead of a 4-wire, fit a jumper between ter-
minals 10 and 11
A
and another one be-
tween 12 and 13,
as indicated in the
scheme.
