Before connecting the power supply, please note the follow-
ing:
S
Avoid long distances between the power unit and the
valve terminal. If necessary, calculate the maximum per-
mitted distance as described in Appendix A.

= 24 V):
Operating voltage (pin 1) = 2.2 A
Operating voltage (pin 2) = 10 A
S
If necessary, calculate the complete current consumption
as shown in the table below and then select a suitable
power unit and suitable cable cross-sectional area.
3.3.1 Calculating the current consumption
The table below shows you how to calculate the complete
current consumption for the valve terminal. The values speci-
fied have been rounded up. If you wish to use other valves or
modules, please refer to the relevant technical specifications
for their current consumption.
