instructions and warnings carefully and follow all the warning signs attached to the
device. Make sure the warning signs are legible and replace missing or damaged

WARNING!
HAZARDOUS VOLTAGE!

Make sure that you are not working on live devices. Deenergise the system
(according to the circuit diagram).
 Before working on the lift control system, ensure that no voltage > 50 V AC is
available.
 Plug must not be inserted if the corresponding devices are not switched off.
 Handling rules for sensitive electronic boards must be applied (protection
against electrostatic charging).
 Before connecting to supply voltage, check whether the information on the
identification plate of the control system conforms to the connection values.

During the electrical installation, the general installation regulations must be
followed. These include:
1. VDE 0100 provision for setting up power installations with rated voltages
up to 1000 V
2. DIN EN 60204-1 (VDE 0113) Provision for electrical equipment of
processing machines.
3. DIN EN 50178 (VDE 0160) Equipment of power plants with electronic
equipment.
4. Statutory accident prevention regulations e.g. BGV A2.
 If the lift control system or associated components are used in special
applications (e.g. area with potentially explosive atmosphere), the standards
and regulations necessary therefor must be complied with.
 If an uninterruptible power supply (UPS) is present in the control system,
switching off the main switch is not sufficient to deenergise the system. The
UPS must be separately switched off.
WARNING!
Cables and plugs may only be mounted or removed in a deenergised state.
