Installation and operating instructions Liftson M-2V-208
The mains is connected to the terminals of the main switch in the EC-Drain LS2 switchgear.
Observe the installation and operating instructions for the switchgear!
The Liftson M-2V-208/...M single-phase version is intended for operation on a power sup-
ply network with a system impedance at the house connection of Z
acc. with DIN EN/IEC 61000-3-11 for a maximum number of 2x45 switching operations
per hour.
NOTE: If the mains impedance and the number of switching operations per hour is greater
than the values specified, because of the unfavourable mains conditions, the unit may
cause temporary voltage drops and also disturbing voltage fluctuations (flickering).
Therefore, measures may be necessary before the unit can be operated correctly on this
connection. The necessary information must be obtained from the electricity supply com-
pany and the manufacturer of the device.
The Liftson M-2V-208 unit is equipped with an acoustic signal transmitter in the switch-
gear in the factory.
An external alarm switchgear, a horn or flashing light can be connected via a potential-free
contact (SSM) in the switchgear.
Contact load:
Connection of the external alarm signal
DANGER! Risk of fatal injury!
When working on the open switchgear, there is a danger of electric shock from touch-
ing the live components.
The work may only be carried out by skilled personnel.
To connect the alarm signal, switch the device so that it is voltage-free and secure it
against being switched on again without authorisation.
Observe the installation and operating instructions of the EC-Drain LS2 switchgear!
contact according to the wiring diagram.
and tighten the threaded cable connection.
NOTE: In the factory settings, the alarm signal triggers when the tank filling level is about
220 mm above the upper edge of the unit's installation surface. This is to be observed
when drainage fixtures are also to be secured with the unit's alarm which lie relatively low
(e.g. floor drains).
It is recommended that commissioning be carried out by Salmson After-Sales Service.
CAUTION! Risk of damage!
Dirt and solids as well as incorrect commissioning can lead to damage to the unit or
individual components during operation.
