3.4 Power Supply Connection
WARNINGS
Check that the voltage supplied by the mains corresponds to the detector’s supply voltage: this is
indicated on the device’s power supply adapter and on the factory test sheet at the end of this booklet.
Use of the wrong voltage can seriously damage the Metal Detector.
A protection switch should be connected up between the mains supply and the Power Supply Unit. The
external grounding line should conform to standards and should not in any case have a resistance
greater than 3 Ohm.
All connecting cables between the gate and the power supply or other external devices must be properly
secured and protected so as to achieve the best performance from the detector and avoid accidental
injury to people who might trip over them.
Lower Connection Module
Insert the connector into the ‘30Vdc’ socket in the connection panel.
Panel Version:
secure the cable by attaching the strain relief.
Column Version:
insert the cable into the corresponding groove. Place the unused caps into
the other grooves and close the connections compartment
Connect the AC/DC adapter to the mains socket: the LED
power indicator on the adapter, if present, will light up.
[OPTION]
Version with protection covers
Operate as described in the previous step, but passing the output cable of the AC/DC adapter through one of the
strain reliefs present on the protection cover.
Connect the input cable of the AC/DC adapter to the mains. NOTE:
the input cable is not fitted with plug, to allow it to pass inside
conduits; carry out the wiring ensuring that the overall protection
degree of the system is not decreased.

Protection Ground
On demand, the input cable is fitted with a removable watertight plug. In
case of outdoor installation, connect it to a receptacle with the same
protection degree. Watertight plug and connector must be fully engaged
so no gap is visible between mating surfaces. Improper engagement voids
watertight integrity and may result in shock hazard if exposed to
water/mud/snow. Take care that the overall protection degree of the
system is not decreased.
Upper Connection Module
Use an accessory
cable extension
, fitted with a 9-pole male
sub-D connector and a 4-pole female plug. This cable allows the
AC/DC adapter to be connected to PS/COM port located on top of
the TX antenna. Insert the cable into one unused groove and make
it exit from the protection covers keeping it close to the TX antenna.
Code:
64228,10m-length extension cable; 68346, 20m-length extension cable
Note
: use Top Power Extension Adapter, code 46650, if all connections
available on PS/COM port are necessary.
