3.1. Installation of BVA
Installation of BVA devices must be implemented near buttons, to make its installation easier and to
have good access to connectors from both sides. Moreover, it is highly recommended the installation of
the devices at half of the height of the floor, in order to avoid any interference with any devices located
at upper and/or lower floors.
Furthermore, switching off the power supply of the facility is recommended to be sure that the working
environment is safe.
It may be necessary to disassemble the lift car operating panel or external buttons for accessing at its
rear part, where the BVA device will be installed, in a way that the device will not be accessible by the
user of the lift.
