DIN 8 modules A
- Connect the two wires of the telephone to
terminals L- and L+ (telephone pair). The maxi-
mum distance between the interface and the
last telephone is 350m with 0.6mm² pair. Do
not lay the telephone cables together with
electrical cables.
- Connect the five wires of the intercom system
to terminals 1, 2, 3, 5 and 6.
- Connect the two wires of the electrical mains
to terminals 0 and 230 (or 0-127 according to
the ratings of the mains). It is necessary to
provide a disconnecting and safety bipo-
lar switch before the device.
- Insert the 2 plastic protection of the terminal
covers supplied with the product.
