Wiring diagram/terminal plan
The wiring diagram/terminal plan 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 down-
loaded directly from the Internet (www.auma.com).
Danger due to incorrect electrical connection!
Failure to observe this warning can result in death, serious injury, or prop-
erty damage.
Ò
The electrical connection must be carried out exclusively by suitably
qualified personnel.
Ò
Prior to connection, observe general references contained in this clause.
Ò
After connection but prior to applying the voltage, observe the Commis-
sioning and Test run clauses.
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 can be derived from the current
consumption of the motor plus the current consumption of the controls.
Motor current consumption:
Refer to name plate on motor (nominal current).
Current consumption of the controls depending on the mains voltage:
100 to 120 V AC = max. 650 mA
208 to 240 V AC = max. 325 mA
380 to 500 V AC = max. 190 mA
24 V DC (+10 %/–15 %) = max. 500 mA, filter capacitor 2200 µF
Current consumption for actuator with 1-ph DC motor:
24 V DC (+10 %/–10 %) = max. 750 mA, filter capacitor 2200 µF
The maximum permissible fuse for controls with a rated power of 1.5 kW is
16 A (gL/gG); for controls with a rated power of 7.5 kW, the value amounts
to 32 A (gL/gG).
WARNING
Cable installation in accordance
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.
.
The interference immunity of signal and bus cables increases if the
cables are laid close to the ground potential.
.
If possible, avoid laying long cables and make sure that they are
installed in areas being subject to low interference.
.
Avoid long parallel paths with cables being either susceptible to interfer-
ence or interference sources.
