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 RedMax 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. For
electrical connection inside hazardous areas an terminal box is requested (e.g. type
RedBox).
Attention: If the actuator is put out of operation all EEx-rules and regulation must be
applied.
B. Shaft connection, selection of running time, heater
RedMax actuators are equipped with a direct coupling double squared shaft connection
of 16 x 16 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 selscted on site.
The integral heater is for ambient temperatures down to -40°C.
C. Minimum load
Minimum load not less than 20% of the rated torque, min.10 Nm
D. 3-pos control mode
See extra information EL-M.
E. Spring return
Spring return function works if the supply voltage (terminal 1 or 2) is cut. 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-M.
G. Excess temperature
In acc. to the ATEX rules and regulations EEx actuators must be protected against
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.
RedMax 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.

RedSwitch is an accessory to RedMax actuators size S,
fixing directly onto the actuator. RedSwitch are aux.
switches with with 2 potential free contacts, adustable
on site. The electrical wiring needs an terminal box.
For electrical connection of an RedMax inside the hazar
dous area an terminal box is required.
RedBox-3P for RedMax-50.75,..-100,..-30-F,..-50-F
RedBox-Y/S for RedMax-...-S integral aux. switches
To adapt the RedBox direct to the actuator housing an
additional accessory type MKK-M is required.
