Protection classes
In completely mounted condition and under consideration of the following hints
assembled, the brake as standard execution (as shown in fig 3) complies with
protection class IP 66, in accordance with DIN 40050 and DIN VDE 0530.
When using original Stromag accessory, such as terminal box, cable glands (see Fig. 1)
the type of protection is maintained. The same applies when the speed encoder is rigidly
connected to the cover by means of a flange gland which is sealed by round ring.
Sealings of through-shafts (by means of shaft seal ring), reduce the type of protection in
relation to the execution. Please consult the manufacturer.
Important note!
The contact surfaces of the brake to the motor, as well as the surfaces of the
"speedometer connection" option shall be sealed with suitable means (e.g. Hylomar or
sealing ring) to guarantee the protection class.
The user has to provide a sealing element on the shaft in direction to the motor side in
order to prevent the penetration of grease from the motor bearing.
