Electrical connection
All actuators are equipped with a universal supply unit working at a voltage range from
24...240 VAC/DC. The supply unit is self adjusting to the connected voltage!
The safety operation of the spring return function works if the supply voltage is cut.
Installation
Ex area –
zone 2, 22
Safe area
supply *
24...240 VAC/DC ± 10 %
* electrical wiring see diagrams
For electrical connection inside hazardous areas a terminal box is required (e.g. RedBox).
An over-current protection fuse < 10 A has to be provided by installer.
Note: the initial current is appr. 2 A for 1 second.
Accessory RedBox – adaptable terminal box
For electrical connection of ...Max actuators inside the
hazardous area an Ex-e terminal box is required.
RedBoxes are appropriate terminal boxes and placed at
the disposal. To adapt the ...Box directly to the actuator
housing a mounting bracket type MKK-S is required.
RedBox- Y/S for ...Max-...-Y and ...-YF with integral
auxiliary switches
Modulating – with / without spring return (no feedback) SB 5.2 3-pos. – with / without spring return + feedback SB 5.3
Modulating / 3-pos. – with / without spring return SB 5.0 Modulating – with / without spring return (no enforcement) SB 5.1
Selection of running time for spring return:
Spring return in ~ 10 s = Standard wiring
Spring return in ~ 3 s = Additional wiring on terminal 5
Selection of running time for spring return:
Spring return in ~ 10 s = Standard wiring
Spring return in ~ 3 s = Additional wiring on terminal 5
Selection of running time for spring return:
Spring return in ~ 10 s = Standard wiring
Spring return in ~ 3 s = Additional wiring on terminal 5
Selection of running time for spring return:

3-pos. control mode:
▪ a closed, b open – ON (OFF) in acc. to left/right mounting of actuator
▪ b closed, a open – OFF (ON) in acc. to left/right mounting of actuator
Function and enforcement control of switch a and b in modulating mode:
▪ a closed – Forced-ON (OFF) in acc. to left/right mounting of actuator
▪ b closed – Forced-OFF (ON) in acc. to left/right mounting of actuator

To adjust the signal input /output to the angle of
rotation of the damper/valve the button (T) must
be pushed for a minimum of 3 sec.

Attention
During commissioning apply a self adjustment drive.
Regard duty cycle at motor running times!
Never use spring return actuators without external load.
