Basic information
Danger due to incorrect electrical connection
Failure to observe this warning can result in death, serious injury, or property damage.
→
The electrical connection must be carried out exclusively by suitably qualified
personnel.
→
Prior to connection, observe basic information contained in this chapter.
→
After connection but prior to applying the voltage, observe the <Commissioning>
and <Test run> chapters.
Wiring diagram/terminal
plan
The pertaining wiring diagram/terminal plan (in German and English language) is
attached to the device in a weather-proof bag, together with these operation
instructions. It can also be obtained from AUMA (state commission no., refer to name
plate) or downloaded directly from the Internet (www.auma.com).
Protection on site
For short-circuit protection and for disconnecting the actuator from the mains, fuses
and disconnect switches have to be provided by the customer.
The current values for respective sizing is derived from the current consumption of
the motor (refer to electrical data sheet) plus the current consumption of the controls.

If controls are mounted separately from actuator (controls on wall bracket): Consider
length and cross section of connecting cable when defining the protection required.
Power supply for the
controls (electronics)
If the controls (electronics) are supplied externally with 24 V DC and DC motors (24
V DC, 48 V DC, 60 V DC, 110 V DC, 220 V DC) are used simultaneously, the 24 V
DC voltage supply for the controls should be ensured via the XK25/26 terminals,
separately from the power supply (U1, V1). In case of common supply using a single
cable (links from U1, V1 with XK25/26, for 24 V DC only !!!), short-term excess or
falling below the permissible voltage limits can be the consequence during switching
(24 V DC +10 %/–10 %). Any possibly incoming operation commands are not
executed outside the admissible limit values. The controls briefly signal a fault
condition.
Potential of customer
connections
All input signals (control) must be supplied with the same potential.
All output signals (status signals) must be supplied with the same potential.
Safety standards
All externally connected devices shall comply with the relevant safety standards.
Cable installation in ac-
cordance with EMC
Signal and bus cables are susceptible to interference.
Motor cables are interference sources.
●
Lay cables being susceptible to interference or sources of interference at the
highest possible distance from each other.
