6 Electrical connection
Electric shock due to presence of hazardous voltage!
Failure to observe this warning could result in death, serious injury, or property dam-
age.
à The electrical connection must be carried out exclusively by suitably qualified per-
sonnel.
à Prior to connection, heed basic information contained in this chapter.
Risk of immediate actuator operation when connecting to mains!
Risk of personal injuries or damage to the valve.
à Check operation signals and operation behaviour prior to switching on the mains
voltage.
à Ensure that the tripping conditions for the failure behaviour are not fulfilled when
switching on.
à Ensure that the tripping conditions for the EMERGENCY behaviour are not fulfilled
when switching on.
Reasons for immediate operation:
• The signal and fieldbus cables are connected and a respective operation com-
mand has been issued.
• The "Failure behaviour" function was configured as to ensure that this state results
in an operation once the mains voltage is applied. Factory setting parameter
Failure operation: STOP (the actuator stops).
• The "EMERGENCY behaviour" function was configured as to ensure that this
state results in an operation once the mains voltage is applied. Factory setting
function EMERGENCY behaviour: Function not activated.
The pertaining wiring diagram/terminal plan (in German or English) is attached to the
device in a weather-proof bag, together with these operation instructions. It can also
be requested from AUMA when indicating the order number (refer to name plate) or
downloaded directly from our website (www.auma.com).
The actuators are suitable for use in TN and TT networks. For IT networks, a suitable,
approved insulation monitor is required, e.g. an insulation monitor measuring the pulse
code.
Type of current, mains voltage and mains frequency must match the data on the name
plate, Name plate [} 10].
For short-circuit protection and for disconnecting the actuator from the mains, fuses
and disconnect switches or circuit breakers have to be provided by the customer.
When using DC current, select circuit breakers suitable for DC applications.
For circuit breakers, the following sizing/characteristics are recommended:
