Obligatory connections
The product is served with 230V AC. The connection is marked with N and L on the
product. One must install a 2-pole switch on the power intake of the product.
When the product is connected to systems where an N-neutral conductor exists, the
phase conductor (L1) must be fused. An example of this kind of system is a TN-C-S
system. Most cabins and/or houses have this kind of system.
If the product is connected to a system where a N-neutral conductor does not exist,
or if the system consists of one-phase 2 conductors (L1 and L2) both of the phase
conductors must be fused. IT-systems are examples of these kinds of systems.
Fuses used must be 10A - 16A.
The included antenna must be connected to the antenna input of the unit and must be
placed on the outside of the fuse box. The antenna must not be placed on the inside of
the fusebox or directly on the fusebox, as this will cause noise and subsequent lack of
communication.
The product must only be installed in an approved fuse box / installation box.
