2 Safety instructions
2.1 General safety information
| INTORQ components ...
– ... must only be applied as directed.
– ... must not be commissioned if they are noticeably damaged.
– ... must not be technically modified.
– ... must not be commissioned if they are mounted incompletely.
– ... must not be operated without the required covers.
– ... can hold live as well as moving or rotary parts during operation according to their
degree of protection. Surfaces may be hot.
| For INTORQ components ...
– ... the documentation must always be kept at the installation site.
– ... only permitted accessories are allowed to be used.
– ... only original spare parts of the manufacturer are allowed to be used.
| Observe all specifications given in the attached documentation.
– This is the prerequisite for safe and trouble−free operation and for achieving the
specified product features.
| Only qualified, skilled personnel are permitted to work on and with INTORQ
components.
In accordance with IEC 60364 or CENELEC HD 384, qualified, skilled personnel are
persons ...
– ... who are familiar with the installation, mounting, commissioning, and operation of
the product.
– ... who have the qualifications necessary for their occupation.
– ... who know and apply all regulations for the prevention of accidents, directives, and
laws relevant on site.
| Risk of burns!
– Surfaces may be hot during operation! Provide for protection against accidental
contact.
| Risk of injury due to a rotating shaft!
– Wait until the motor is at standstill before you start working on the motor.
| The friction lining and the friction surfaces must by no means have contact to oil or
grease since even small amounts reduce the brake torque considerably.
| The brake is designed for operation under the environmental conditions that apply to
IP54. Because of the numerous possibilities of using the brake, it is however necessary
to check the functionality of all mechanical components under the corresponding
operating conditions.

2.2 Application as directed
| Drive systems
– are intended for use in machinery and systems.
– must only be used for the purposes ordered and confirmed.
– must only be operated under the ambient conditions prescribed in these Operating
Instructions.
– must not be operated beyond their corresponding power limits.
Any other use shall be deemed inappropriate!
Possible applications of the INTORQ spring−applied brake
| Humidity: no restrictions
| Ambient temperature:
– −5°C to +40°C (standard)
| At high humidity and low temperature:
