8.2.2 Set-up and start-up
The brakes must not be put into operation when:
•
power supply cables/wires or connections are damaged.
•
the solenoid housing or coil sheath is damaged.
•
other defects are suspected.
8.2.3 Installation
The voltage and voltage type specified on the rating plate must be strictly observed when connecting the
brakes described in these Operating Instructions. Sufficient heat dissipation must be ensured when the
brake is fitted to or incorporated into other equipment.
Adequate precautions must be taken to avoid overvoltage during disconnection or voltage peaks. The
magnetic field of the products may cause interference outside the brake or even feedback to the brake in
case of adverse installation conditions. Should you have queries concerning mounting and fitting conditions,
please contact the brake manufacturer and ask for clarification.
Adequate safety measures (DIN VDE 0848, part 4; DIN 31000/VDE 1000; DIN VDE 0100, part 0420) must
be taken by the brake user to avoid hazards to persons and animals or damage to equipment caused by:
•
direct or indirect effects of electromagnetic fields,
•
heated
components,
•
mobile
parts.
8.2.4 Operation
Make sure that live components such as plug contacts or the field coil are not exposed to water. The brake
cable connections must not be crushed, squeezed or exposed to mechanical loads. Make absolutely sure
that the friction surfaces of the friction elements are not contaminated with grease, oil or other liquids to
avoid substantial torque reduction. Bear in mind that the original torque cannot be restored even if the friction
surfaces are cleaned after contact with liquids. The gradual brake wear and the resulting torque reduction of
spring-applied brakes must be taken into consideration during set-up. Due to the diverse ambient conditions
in which the brakes may be used, always check that the brake is in perfect working order before start-up.
Torque reductions cannot be excluded if the brake is used for applications where only minimum friction work
is required. In such cases, the user should ensure that the brake occasionally performs sufficient friction
work. Operation of the brake as pure holding brake without friction work is only allowed after prior
consultation with the manufacturer. If brakes equipped with hand release lever are used, the lever must only
be moved up to the release position in order to avoid deformation or breaks.
Note!
The maximum air gap s
max
(see Table 28/1 "Technical specifications") must not be exceeded throughout the
entire brake service life. (Please refer to Section 4 "Maintenance" for details.)
8.2.5 Maintenance and repair
Repair work must only be carried out by suitably qualified personnel (definition to IEC 364). Failure to
perform repairs according to requirements may cause serious personal injury or equipment damage.
Make sure that no voltage is applied to the brakes when carrying out maintenance work.
Danger!
The warning "DO NOT OPEN WHILE ENERGISED" affixed to the spring-applied single-disc brake must be
strictly observed.
