Warnings:

•

for lengths > 10 m, only use shielded cable, with the shield connected to earth;

•

a 0 to 10 Vdc analogue output can be connected in parallel to other outputs of the same type, or alternatively to an external source of voltage. The higher
voltage will be considered. Correct operation is not guaranteed if actuators with voltage inputs are connected;

•

power the VG-VG0 analogue outputs at the same voltage on G-G0: Connect G0 to VG0 and G to VG. This is valid for both alternating and direct current
power supplies.

Insulation distance

The relay outputs have diff erent features depending on the model of controller. The outputs can be divided into groups. The relays belonging
to the same group (individual cell in the table) have basic insulation and therefore must have the same voltage. Between groups (cells in the
table) there is double insulation and consequently these may have diff erent voltages. There is also double insulation between each terminal of
the digital outputs and the rest of the controller.

Tab. 2.k

Warnings:

•

if the load requires higher current, use an external SSR;

•

to power external loads, use the same power supply as the pCO (connected to terminals G/G0); this must always be dedicated and not in common with the power
supply to other devices on the electrical panel (such as contactors, coils, etc...);

•

the groups that the digital outputs are divided into have two common pole terminals to simplify wiring;

•

make sure that the current running through the common terminals does not exceed the rated current of an individual terminal, that is, 8 A.
