4.1 Cabin Switch Connection
The Cabin Switch unit helps you connect up to 4 IP devices located in the lift cabin. It
transfers data from the DSL line to 4 Ethernet ports, which support the rate of 10 or
100 Mbps. Two ports provide PoE 802.3af Class 2 (6.49 max) and allow up to 2
devices without power supply to be connected. Typically, they include an emergency
communicator, an IP camera and an access system reader.
It is interconnected with the
main unit and communicates with it using a
2N LiftGate
®
carried in a towrope from the lift cabin to the machine room.
2-wire cable
The Cabin switch unit is intended for lift cabin installation and suspended using screws
or mounted on a DIN rail. There is a DIN rail mounting profile with a lock on the cabin
unit back side. Put the upper profile side on the DIN rail and push the cabin unit
bottom to fit and lock the cabin unit to the DIN rail. To release the cabin unit from the
DIN rail, pull the DIN rail lock a little, using a screwdriver, for example. Now remove
the cabin unit from the DIN rail.
1 or 2 48 V power supplies (marked as 1xPS or 2xPS) are available on the main unit for
feeding the cabin unit, depending on the device version. Each power supply is able to
feed 1 or 2 cabin units, i.e. the total of up to 4 units in the two-supply version. Each
cabin unit can be installed in a different lift cabin. The power supply is short circuit
resistant and has a resettable electronic fuse.
Warning
As power supplies warm up during operation, it is necessary to install
the device in such a manner that air can flow from the fan to the
ventilating holes on the other side of the device.
