A. Installation, commissioning, maintenance
The cable of the actuator must be installed in a fixed position and protected against
mechanical and thermical damage. In acc. with operation InMax actuators are
maintenance free. Nevertheless maintenace must comply with regional standards,
rules and regulations.
The actuators must not be opened by the customer. For outdoor installation a protective
housing against rain, snow and sun should be applied to the actuator, as well as a
constant supply at terminal 1 and 2 for the integral heater.
B. Shaft connection, selection of running time, heater
InMax actuators are equipped with a direct coupling double squared shaft connection
of 12 × 12 mm. The housing of the actuator is axially symmetrically built to select
open/close direction of the spring return function by left/right mounting.
In acc. to the actuator type 5 different motor running times can be selected on site. The
integral heater is for ambient temperatures down to -40°C.
C. Working with 3 sec. motor running time
See extra information “EL”.
D. Spring return
Spring return function works if the supply voltage (terminal 1 or 2) is cut or open the wire
3. In the event of an electrical interruption, the spring returns to its end position.
F. Operation at an ambient temperature below -20°C
See extra information “EL-S”.
G. Excess temperature
An internal thermostat guarantees the temperature class in the event of failure. If this
thermostat is working the actuator must be sent to the factory.
InMax actuators are equipped with an additional temperature sensor to stop the
actuator before reaching this max. temperature. In this case the failure must be
eliminated immediately on site.
H. InPro-TT-..
The actuator works only with the temperature sensor type InPro-TT-..
Details see extra information “ME”.
Details see extra information “ME”.
InSwitch is an accessory to InMax actuators size S, fixing
directly onto the actuator. InSwitch are aux. switches
with with 2 potential free contacts, adustable on site.
For periodic inspection of fire dampers cut of the the supply line (cut off the current of
the actuator)
The switch contact on InPro-TT-.. is only for test aims of actuators function.
For electrical connection of an InMax actuator.
To adapt the InBox direct to the actuator housing an
additional accessory type MKK-S is required.

Safety temperature sensor – InPro-TT-..
The safety thermostat type InPro-TT-.. is passive and
potential free for use in safe circuits, directly connectable
to the circuit of the InMax-..-BF1 actuators. The sensor
switches at an ambient temperature of 72°C and starts
the fail safe spring return function of the actuator.
