classification of the
measuring circuits
(CEI EN 61010-1)
Category I (J5, J7, J20) 24 Vac/Vdc
Category III (J8, J19) 230 Vac
WARNINGS:
- 230 Vac 50/60 Hz (10/-15%);
- the two 230/24 Vac inputs present on J8 and J12 have the same common pole and
consequently will be both 24 Vac/Vdc or both 230 Vac. Basic insulation between the two inputs;
- for DC inputs, connect the negative pole to the common terminal.
Note: separate as much as possible the probe and digital input signal cables from the cables carrying the
inductive loads and the power cables, to avoid possible electromagnetic disturbance.
