3. Proper use / specified purpose
3.
The brake may only be connected within the voltage marked on the type label of the brake.
240VAC = 220 … 240 VAC, single phase
480VAC = 380 … 480 VAC, single phase
With 50 Hz or 60 Hz (no adjustment necessary) and corresponding to the technical details. The
electrical connection see chapter 8.4.
The brake is designed for use as a holding/parking brake and/or stopping brake.
Other uses are improper and incompatible with the specified purpose. RINGSPANN assumes no
liability for damages resulting from improper use. The risk is assumed by the user alone.
4. Improper use
Operating the brake with other supply voltage as specified on the nameplate is prohibited.
Unauthorized constructive modifications of the brake are similarly prohibited. If the grub screw
pos. 44 is provided with sealing wax at the factory, the clamping force on the brake must not be
adjusted by the customer!
For damages caused by switching the brake without brake disc or unauthorized constructive
modifications RINGSPANN assumes no liability for damages resulting from improper use. The
risk is assumed by the user alone.
5. Condition upon delivery
The brake is tested prior to delivery. The braking force is adjusted to the maximum braking force.
6. Handling and storage
The weight of the brake depends on the size, between 6,5kg and 50kg, see also chapter 2.3.
The brake is delivered with anti-corrosion protection and can be stored in an enclosed, dry space
for up to 12 months. It is important to prevent condensation from forming. Moist storage areas are
unsuitable.
7. Technical requirements for safe and reliable operation
Mounting the brake to stable, low-vibration machine components ensures low-screech, low-noise
braking.
To protect the brake electronics, the installation of surge arresters are mandatory. These surge
arresters (per phase one) must be connected between the customer's switching relay and the
brake electronics. In this case, the surge arrester of L1 and L2 is switched to N or PE in order to
derive mains disturbances. For 230 / 400V electric grids e.g., surge protection switch of the brand
"Bourns 1250-xS-230" can be used. In 480V mains overvoltage circuit breaker type "Bourns
1250-2S-400" can be used.
8. Installation of the RINGSPANN brake
8.1 General instructions for assembly and installation
Before installing the brake, the brake disc must be cleaned with alcohol, e.g. ethyl or isopropyl
alcohol or a water-based surfactant solution (soapy water, etc.) and then rubbed dry with a clean
cloth.
When cleaning the brake disc with a thinner, acetone or a brake cleaning agent, it is im-
portant to ensure that neither these cleaners nor any cleaner residues come in contact with the
brake pads. This is especially important in the case of brakes used only as parking brakes, as no
dynamic braking operations take place during which thinner residues would be rubbed off the
brake disc.
Please note!
Oil and rust-proofing-agent residues reduced friction coefficient and thus dimin-
ish transmissible braking torque substantially!
