3.2 Equipment Connection to the Power Supply
Even when the equipment is DC powered ( 13,8 V ), it still operates properly, but it is advisable
to power it by Alternating Current ( 19 or 24 V~ ) or (24 V ) using the power supply and battery
charger included.
3.2.1 Connection to the Power Supply
The connection from the equipment to the
optional transformer
must be as short as possible
(less then 4 meters), and the section of the conductor must not be less than 1.5 mm². The
connection from the transformer to the 230 V~ mains, must have the same characteristics. The
power supply cables connecting transformer with equipment, must be electrically shielded and
the shield must be connected to earth tap. The low voltage conductors (19 or 24 V~) have to be
connected to the terminal block MS1 (1 and 2) of the power supply and battery charger circuit.
The protection fuse F1 is 2 A (T2A) slow-blow type.
The
transformer characteristics are following:
•
primary voltage: 230 V~
•
secondary voltage 19 V~
•
minimum power 30 VA
Note: use only safety transformers
(example Certified EN 60950)
Make sure to connect the body of the transformer to hearth tap.
The transformer connection to the main (230 V~), must be carried out through
one circuit breaker having the following characteristics:
•
bipolar with minimum distance between contacts equal to 3 mm
•
provided in the fix part of cabling
•
easily accessible
It is possible to use the toroidal safety transformer mod. TRTOR installed inside the Tx e Rx
CORAL-S heads.
However laws and standards concerning installations of devices permanently connected
to the main (230 V
~
), must be strictly respected (in Italy Law 46/90 and standard CEI 64-8).
3.2.2 Connection of stand-by Battery
Into each equipment head there’s the housing for an optional rechargeable back-up lead Battery
12 V
2 Ah (optional). The battery is charged by the internal power supply, through the red and
black fastons and wires connected to the terminal block MS2 of the power supply an battery
charger circuit (both Rx and Tx heads). The protection against overload and/or battery polarity
inversion, is provided by an auto resettable fuse (300 mA) The back-up lead battery allows more
than 24 hours of perfect working to the barrier head (TX or RX), in case of mains supply missing.
A fault condition is activated if continuously for 3 hours the mains supply is missed.
Note:
package, of the optional standby battery, must have a flame class equal or better than HB
( UL 94 Standard ).
