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 TOCAhome product.
The inside and outside unit have to be connected via a 4-lines wire (bell
wire, CAT 5/6, …) with a minimum line diameter of 0,75mm² (gauge 21)
using connection clamps 1-4. In the case of a wire length of more than
20m the diameter of the wire has to be enlarged and a screened cable has
to be used.
1 relay (3 relays with the product ekey
®
TOCAhome 3) is available for
controlling external switchgear. The programming is carried out via the
programming menu. The relay is equipped with a change-over contact,
which is freely usable, the maximum switching power is 250V~5A. Each
door opener has to be connected to a dedicated power supply without
exception (don’t use the power supply provided with you TOCAhome
product!).
The connection wire between outside and inside unit 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.
Remark:
The cables are not protected against reversed polarity.
Note:
It is strongly recommended to have the electrical connection done only
by qualified personnel!
