7 Electrical Installation
7.1 Preparation
Prior to installing and commissioning this unit carefully read the
safety instructions and warnings and pay attention to every warning
label attached to the unit. Make sure that the warning labels are read-
able at all times and replace missing or damaged labels.
ATTENTION! DANGEROUS VOLTAGE !
• Make sure that the devices you work on do not carry current! Dis-
connect the system from the power (according to the circuit dia-
gram.
• Before carrying out any work on the lift control, ascertain that it
does not carry any voltages of > 50 V AC .
• Plugs must not be inserted in sockets as long as the according
devices are not switched off.
• Pay attention to the rules concerning the handling of delicate elec-
tronic printed circuit boards (protection against electrostatic
charges)!
• Before connecting the device to the power supply, check whether
the indications on the type label of the lift control correspond to the
values of the connected load.
• All electrical installations must comply with the general installation
regulations, including:
1. VDE 0100 Bestimmung für das Errichten von Starkstromanlagen
mit Nennspannungen bis 1000 V (rules for the installation of
power engineering systems with nominal voltages of up to 1000
V, from the association of German electrical engineers).
2. DIN EN 50178 (VDE 0160) Ausrüstung von Starkstromanlagen
mit elektronischen Betriebsmitteln (equipping power engineering
systems with electric operating resources, from the association of
German electrical engineers).
3. Legal regulations for the prevention of accidents, such as for
example BGV A2.
4. Legal regulations for the prevention of accidents, such as for
example BGV A2.
• If the lift control unit or related components are used in special
environments (e. g. ex-area), it is to be ascertained that the relev-
ant standards and regulations are adhered to.
• If the lift control unit is fitted with an uninterruptable power supply
(UPS), it is not be sufficient to disconnect the power to the unit with
the main switch; the UPS has to be turned off separately.
