Page 9: Installation And Start-Up
3. Installation and start-up Normally, it is required to have one Nayar Switch more than the total number of lift cars in the installation. As an example, at an installation with a single lift car, two Nayar Switches are necessary; at an installation with two lift cars, three Nayar Switch are required.

3.2. Nayar Switch installation at the lift car 1. Place the device at the lift car, so as to be accessible to all the connectors of the Nayar Switch by the installer. The device must not be able to be manipulated by the elevator user.
Page 14 Switch - 1_en 4. If it is desired to use the Nayar Switch in order to feed an electronic device, VOUT connector must be used. The polarity of the DC connector must be respected. It is highly recommended to use it to feed Advertisim devices.
Page 15: Configuration Of Bus Termination Resistors
Nayar Systems Switch - 1_en 3.3. Configuration of bus termination resistors Depending on the installation, a specific configuration of bus termination resistors has to be applied. Bus terminating resistors are configured by using the microswitch 2 at the device rear panel.

Page 17 Switch B2 OFF Switch Bn ON Where Bn corresponds to the Nayar Switch placed at the last lift car of the installation (it is not recommended to connect more than 8 lift cars). Therefore, the Nayar Switch whose microswitch 2 must be at ON position are those corresponding to the first and last lift car.
Page 18 In case of an installation with three or more lift cars, the following star-wired installation schematic must NOT be reproduced. When installation and start-up is completed correctly, all lift car Nayar Switch power and Internet connectivity LEDs should be lit up.
