Installation and Operating Instruction for ROBA-stop
Dual Circuit Fail Safe Brake Type 892.10_.0
Sizes 60 – 2000
Note for electromagnetic compatability (EMV)
There are no emissions from the listed single components within the meaning of EMV guide line 89/336/EWG.
However, increased interference levels can occur when working components are operated outside their specification
limits as for example, energising the brake with rectifiers, phase demodulators or ROBA-switch in the line side.
Therefore, the installation and operating instructions must be read carefully and the EMV guide lines are to be
observed.

Standards and Instructions

ROBA-stop –Z brakes are developed and manufactured in conformance with the national standard DIN VDE 0580 according to the low-
voltage directive 73/23/EWG.
Following directives have been used:
98/37/EG Machinery directive
73/23/EWG Low voltage directive
89/336/EWG EMV-guide line
EN 81-1 Safety regulations for the construction and installation of passenger lifts and goods elevators
BGV C1 (up to now VGB 70) Safety regulations for theatre and stage applications
Following standards are to be observed:
EN 292-1, 292-2 Security of machines
EN 50081-2 Generic specification – interference emission industrial range
EN 50082-2 Generic specification resistance to jamming – industrial range
EN 60204 Electrical equipment of machines
Protection class I: The protection is not only based on the basis isolation, but that all conductive components must be connected with the
protective conductor of the fixed installation. In case the basis insulation fails, no contact voltage can remain existing.
(EN 50144-1, 11.99, classification VDE 0740-1)
Protection IP 10: Protection against foreign substances 50mm diameter (protection of the back of the hand). No protection against
splash water DIN EN 60529).
Ambient temperature:

Conditions of the units

The catalogue values are for reference only, and may vary in certain cases.
When selecting the brake, site of installation, braking torque fluctuations, permissible friction work, behaviour during
run-in, wear and ambient conditions are to be carefully checked and agreed with the unit manufacturer.
The mounting and connecting dimensions at the site of installation must match to the size of the brake.
Observe!
ROBA-stop –Z brakes are designed for a relative switch on period of 60 %.
ROBA-stop –Z brakes are designed for a dry running only.
The braking torque depends on the corresponding running-in condition of the brake.
Protective system for damping of overvoltages, as high inductive voltage peaks occur when the brake is
switched off on the DC side which can result in damage to the coil insulation as well in the burning away of the
switching contact in extreme cases.
Provide additional necessary safety measures against corrosions of the brake, if they are used in extreme
ambient conditions or in the open with direct atmospheric influences. The metallic surface of the brake is
protected against corrosion arranged by the factory.

-20 ° C up to +40 ° C
Attention!
The torque could be severely reduced in case of temperatures over or under the freezing point due to
dewing. The user must provide corresponding counter measures.
Rusting with increased humidity, longer downtime or maritime climate is possible.
In these cases we recommend increased corrosion protection.
Attention!
Should oil, grease, water or similar materials come in contact with the friction surfaces the braking torque
could be reduced.
