Please consider the following measures:
• The control system bp308 exclusively serves as an information
processing device within the lift control system. All control signals
are processed by positive circuitry or via the CAN Bus. The Safety
Regulations TRA and DIN EN 81 are not restricted by the elec-
tronic information processing.
• The control unit has been designed, manufactured and tested in
accordance with DIN EN 81 (TRA) and the VDE regulations. You
must adhere to the relevant regulations for the commissioning of
electric control unit and operating devices. You should also follow
the local lightning protection rules.
• Each control unit comes with circuit diagrams and technical docu-
mentation clearly identified by the control unit number.
• The mounting and installation instructions of third-party device
manufacturers must be followed exactly.
• To conform to the EMC Directives, you have to wire an appropriate
one-phase mains filter into the 230 V AC control circuit and con-
nected signal circuit
• The control lines are to be laid separately from the load lines in
separate cable ducts. Crossing lines are to be laid at an angle of
90°.
• Control devices are always to be connected by applying choke, fil-
ter and shielded cables and according to the mounting and installa-
tion instructions of the manufacturer.
• Ensure that all the devices contained in the cabinet are properly
earthed via short earthing lines with large diameters that are all
connected to a mutual earthing point or earthing bus. It is of partic-
ular importance that every control device connected to an inverter
(e.g. a speed encoder) has short lines with a large diameter and is
connected to the same earthing point as the inverter itself. Prefer-
able are flat lines (e.g. metal brackets) as they have a lower imped-
ance at high frequencies.
• Use shielded or reinforced cables for load lines between drive unit
and inverter or control unit, and connect the shielding/reinforce-
ment to the earth at both ends.
• Data lines (group, data remote transmission, printer connection,
etc.) are generally made from shielded cables. The shielding of
data lines should be connected to the earth at one end
• Mounting racks consist of zinc-plated sheet steel, enabling large
surface earth connection to all control components.
• Interference-proof structural elements improve resistance against
environmental interferences.
• The car is to be connected to the earth by the green/yellow line of
the travelling cable.
