bASIc SAfETY INSTrUcTIONS
1.5 Start-up and operation
The operation must not be started until it is determined that the installation complies with
the machine directive; Account is to be taken of
cAUTION
Pay attention to friction work (speed and the frequency of operation)!
Loss or decrease of braking torque!
► Exceeding the technical specifications can lead to thermal overload
of the lining or magnet and to severe signs of wear on the gearing of
the hub and lining. This can lead to failure of the brake (=>
Friction work switching frequency type N, H, D“
).
1.3 Installation and mounting
NOTICE
Squeezing and pinching of fingers by self-rotation.
►
Before installation, make sure that the drive is load-free.
►
Secure drive against rotation.
Consider the following installation measures to prevent faults
►
Do not operate the brake in an explosive environment.
►
Provide measures against freezing or ice formation on the friction surfaces.
►
Take appropriate measures against high air humidity, aggressive vapours/liquids or
similar that lead to corrosion and 'rusting' of the pole surfaces.
1.4 Electrical connection
DANGEr
Electrical voltage at brake and motor!
Danger to life due to electric shock!
►
Any work on the electrical power supply may only be carried out by
a qualified electrician.
► When carrying out any work on the brake, switch off the supply volt
-
age and secure it against switching on.
►
Never bridge upstream protective devices, not even for test purposes.
►
Standard-compliant testing of the protective conductor connection to
all touchable metal parts.
