Connection terminalsInput terminals:Ø mains neutral230(117) 230V live (117V)Output terminals :C = call tone positive pole– = call tone negative pole– = 8Vdc direct tension ground+ = 8Vdc direct tension output~ = 14 Vac power supply output~ = 14 Vac power supply outputNOTICE:The call tone has a negative pole (-) connected to the – of the 8Vdc tension.InstallationThe installation must be in conformity to IEC regulations.In particular the following precautions must be observed:• All installation’s sets must be used only for the purpose for which they have been designed.• Before connecting the power supply to the mains voltage, check the rating plate.• Before the power supply, it is needed an automatic circuit breaker to protect and section the unit• After installation, reallocate the side covers protecting the wires• Do not close the slots for heat output• Before doing any cleaning or maintenance disconnect the mains acting on the proper switchIn case of failure disconnect the power supply from mains voltage by acting on the mains switch, and call the technicalassistance.Reparations can be done only by an authorised technical assistance service.OperationOn the output terminals the nominal values are available when mains is connected.On terminals C and -- there is a 15V continuous tension that turns into a three-tones note if it is connected to a charge thatabsorbs 100mA at least. Such a signal is very useful to realise the electronic call at the floor using door phones AN9102 orAN9136.Notice that the call signal must be used connecting the – terminal to the ground and the C terminal to the call buttons’common wire in case of 4+n system (positive signal). In case of 1+n door phone systems or video systems the call signalmust be used connecting the – terminal to the buttons’ common wire and C terminal to the ground (negative signal)In case of overload or short circuit, the PTC internal protection works disconnecting the voltage output.To restore the normal functioning, after overload removal, it is needed to disconnect the transformer from the power supplymains and wait few minutes until cooling.
