•
Idle lines of the travelling cable should be connected with one end
to the earth at the control cabinet
•
The components of the control unit conform with the regulations of
DIN EN 81 (TRA) as well as VDE 0100 / 0101 / 0551 / 0660 and
BGV A2. The control cabinets conform to the installation standards
VDE 0660 / part 500.
•
Mains and auxiliary contactors used in the control unit comply with
DIN EN 81 part 1, 13.2, (TRA 260.82) as well as VDE 0660, but at
least equipment class D3.
•
Voltage fluctuations are permissible if they range within a tolerance
of +10% to -20% normally guaranteed by the utility company.
•
Damages for malfunctions caused by an impermissible voltage rise
may not be claimed from the manufacturer.
•
If owners add further coils (inductivities) at their own discretion, it is
be of utmost importance that these coils are interference-proof as
well.
•
DC-powered inductivities such as, for example, in contactors,
relays, brake magnets, lock magnets and hydraulic valves must be
equipped with a diode (1000 V / 1 A), anti-parallel and as near as
possible to the coil (BÖHNKE + PARTNER use a free running
diode).
•
AC-powered contactors, relays, brake magnets, lock magnets and
hydraulic valves are required to be equipped with a RC combina-
tion pitched on the type of coil, in parallel and as near as possible
to the coil (the RC combination of BÖHNKE + PARTNER is univer-
sally usable).
•
AC-powered door operators, braking and locking motors are to be
equipped with a RC combination pitched to the motor type, in par-
allel and as near as possible to the motor coil. The RC combina-
tions are radially connected to the motor coil (the RC combination
of BÖHNKE + PARTNER is universally usable).
•
Interference suppression means are to be properly installed.
