Installation
3.3. Electrical connection
The inside unit has to be supplied with electricity; its voltage is 9 VAC.
Please use the “9VAC – in” connecting clamps and only use the
power supply provided with your TOCAnet product.
Inside and outside units have to be connected to the RS-485 bus using
a bell wire or Cat 5/6 cable
(see the connection scheme below) .
Minimum wire diameter required is 0.6 mm². For the power supply of
the scanner unit, a wire diameter of 0,75mm² (gauge 21) is necessary.
Each door opener has to be connected to a separate power supply! Do
not use the ekey
®
adapter for powering any other electronic devices!
The connection wire between outside and inside units is to be run
separately from electronic house installations, as they send out signals
in the lower voltage area, which can be irritated by other neighbouring
live power cables.
The cables are not protected against reversed polarity.
Note:
It is strongly recommended to have the electrical connection done only
by qualified personnel!
