Basic information
Electric shock due to presence of hazardous voltage!
Risk of death or serious injury!
→
The electrical connection must be carried out exclusively by suitably qualified
personnel.
→
Prior to connection, observe basic information contained in this chapter.
Risk of immediate actuator operation when connecting to mains!
Risk of death, severe injury or damage to valve.
→
Check operation signals and operation behaviour prior to switching on the mains
voltage.
→
Ensure that the tripping conditions for the failure behaviour are not fulfilled when
switching on.
→
Ensure that the tripping conditions for the EMERGENCY behaviour are not ful-
filled 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 para-
meter
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.
Wiring diagram/terminal
plan
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 (state order number, refer to name plate) or
downloaded directly from the Internet (http://www.auma.com).
Permissible networks
(supply networks)
The actuators are suitable for use in TN and TT networks. For IT network, a suitable,
approved insulation monitor measuring the pulse code is required.
Current type, mains
voltage, mains fre-
quency
Type of current, mains voltage and mains frequency must match the data on the
name plate.
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.
For circuit breakers, the following sizing/characteristics are recommended:
