Equipotential Connection - Mec MX975 Manual De Instrucciones

Erroneous connection could lead to overheating of the terminal board which could lead to blowout
and electric shock.
Check that all the connections are tight before connecting the device to the mains.
PE = Yellow/Green: "EARTH" protection conductor.
N = Blue: neutral conductor.
L = Brown, Grey, Black: live conductors
Check there is no static discharge between live and earth. Check the limit switch continuity
between the external casing and the earth wire of the mains. It is advised to use a multi tester to
carry out these operations.
CABLE SUBSTITUTION
This must be carried out by a qualified authorised technician. The earth wire must always be
yellow green.
WARNING: the yellow/green voltage wires in the earth cable must be 3cm longer than the
others.
Proceed as follows to connect the power supply wire to the terminal board:
•
( A1 ) Loosen the tops of the cable gland and open the bottom part of the back of the
appliance by loosening the screws.
•
( A3 ) Loosen the terminal screws and feed the cable conductors through. Take out the
old cable from the cable gland.
• ( A2 ) Feed the new cable through the cable gland. Connect the new cable's conductors
to the terminal following the connection diagram on the label at the lower part of the back of the
appliance. Only connect what is indicated inserting the copper bridge and the electricity cable
together under the screws, in the tightening direction, so the cable and the bridge are tightly fixed
by tightening the screw. The type of cable to be used (HO7RN-F) is indicated on the label for
each connection and the voltage sections in mm².
•
( A4 ) Close the bottom part of the back of the appliance by tightening the screws and fit
the cable by tightening the cable gland top.
Check that all the connections are tight before connecting the device to the mains.
WARNING: Erroneous connection could lead to overheating of the terminal board which could
lead to blowout and electric shock.
Check there is no static discharge between live and earth. Check the limit switch continuity
between the external casing and the earth wire of the mains. It is advised to use a multitester to
carry out these operations
The appliance must be connected to the mains using a H07RN-F cable.

EQUIPOTENTIAL CONNECTION

This connection shall be carried between the different
appliances with the terminal marked by the symbol: (see image).
This terminal enables the connection of Yellow/Green cable with
a section between 2.5 and 10mm² .
The appliance shall be included in an equipotential system
whose efficiency shall be duly verified according to the
provisions of the laws in force.
