MG TR-EVO, Инструкция по эксплуатации, Страница: 8 / 24

A 16A fuse with semi-rapid response should be used as the protective component.
Terminals 3, 4
Output to pulse transformer primary.
The transformer should be dimensioned starting with the size of the element
to control, i.e. the type of alloy, width, thickness and length. (see specific
section).
Unless legislative indications state otherwise, cables with a 2.5mm
2
section
must be used on connection to the primary.
On the connection between the transformer secondary and the heating
element, the cross-section should be chosen according to the currents and
connection lengths involved, a cable with section between 4mm
2
and 8mm
2
is
recommended.
Terminals 5, 6
Device power supply input.
Here, connect the power supply of the device
between 220 and 240 Vac (+15% / -15%). This
line is protected inside the device with a 100mA
fuse.
Connect mains neutral to terminal 5 shared with
the neutral of power output.
Connect mains phase to terminal 6 to supply
device. This connection allows to signal on the
display the possible intervention of the
protection circuit.
The mechanical dimensions and the type of filter
to install are based on the plate data of the pulse
transformer. Contact our technical office for the
relevant dimensioning.
Terminals 7, 8
"ALARM" output
Free contact to signal any faults: this contact is closed in the event of monitored malfunctions, for
example, breakage of the heating element, short circuit, etc. Apply a maximum voltage in
alternating current of 100V/0,5A and continuous current 24V/0,5A.
