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.
