10.1 Determining the size of the power supply unit
The ACS-8 part. No. 026585 is delivered with the power supply and charging unit 010690.02.
The factory settings of the DIP switches of this power supply unit are as follows:
S1/1 S1/2
ON OFF
(The description of the settings can be found in the respective power supply unit documentation.)
If more power is required, the following alternative power supplies are available:
-012168
-012170
The DIP switches of these two power supply units must be set as follows:
S100/1 S100/2
OFF ON
(The description of the settings can be found in the respective power supply unit documentation.)
The ACS-8 can physically hold:
1 x 018003
2 x 018002
The following gives an example of how to calculate the current consumption of an ACS 8 controlling one
door:

Larger actuators (e.g. door strikes) or devices with higher current consumption can be supplied from
external power supply units (see chapters 18.1 and 18.2: If this is the case, +12V DC and 0V are
connected to the external power supply unit and not to terminals 45 and 46).
