Mains Connections; Relay Act Connection; Earth To Chassis Connection; Battery Power Supply - Optimus AXD-30 Operating Instructions Manual

ENGLISH

6.12. Mains connections

On the rear panel there is a CEE22 plug base for the supply,
allowing connection to the mains supply by means of the cable
supplied with the amplifi er.
These amplifi ers are factory-prepared to operate with a mains
voltage of 230V AC. On request they can be supplied prepared
for operation with another voltage (115V CA).
N.B.: This unit must not come into contact with or be
splashed by water.

6.13. RELAY ACT connection

These contacts supply 24V DC (maximum 100mA) when the
speech preference is activated.
They are used to activate external elements that have to be
Eng
activated at the same time that the speech preference is in
operation. The example in Figure 22 shows the connection
diagram of the relay activation output in order to provide
announcement security in the attenuators.
A relay can be connected directly, without additional protective
elements.

6.14. Earth to chassis connection

In all installations it is very important that there is one single
point of connection between the signal earth connection and
the mains supply earth contact. The OPTIMUS units have a
"shucko"-type connector, which enables the chassis to be
connected to the mains earth connection.
If the installation comprises more than one equipment unit,
their chassis will probably be joined, either by means of the
earth terminal of the mains connection, or because they will be
fi tted in a metal cabinet.
If the earth connections are joined by the signal circuits, it is
advisable to remove the jumper between the earth connection
and the chassis from all the units except one, thereby avoiding
noises caused by the loops of the earth connections circuit (see
Figure 23).

6.15. Battery power supply

This supply allows these units to be used in security installations, connecting a 24V DC battery.
The "0" / "I" switch does not interrupt the battery power supply.
The battery fuse is
internal, and its value
varies according to the
model.
