Installation Positions - Madas EVQ-1 Manual Del Usuario

Common procedures (threaded and flanged devices):
• ONLY install the device in the allowed positions
(figure to the side);
• During installation, avoid debris or metal residues
from getting into the device;
• To guarantee tension-free assembly, we recommend
using compensating joints, which also adjust to the
pipe's thermal expansion;
• If the device is to be installed in a ramp, it is the
installer's responsibility to provide suitable supports or correctly sized supports, to properly hold and secure the assembly.
Never, for any reason whatsoever, leave the weight of the ramp only on the connections (threaded or flanged) of the individual
devices;
• In any case, following installation, check the tightness of the plant;
• Wiring cannot have cables connected directly to the coil. ALWAYS and ONLY use the connector/electronic board
recommended by the manufacturer;
• Wire the terminal board (31) with a cable 3x1 mm²,
outside Ø between 8.3 and 9.5 mm using the relative
terminals for cables, as shown in the general figure
on the side. The cable to use must have double
sheathing, be suitable for use outdoors, with
minimum voltage of 500V, and minimum temperature
of 105°C;
To wire the solenoid valve (see the images below):
a. Loosen the 4 fastening screws (1);
b. Remove the cover (2) and loosen the cable gland (3);
c. Pass the cable through the cable gland (3), leaving a suitable length at the end to facilitate wiring to the terminal board
without tensioning or forcing;
d. Secure the cables (duly crimped) to the terminal board (31), connecting terminals 1 and 2 to the power supply and the
earthing cable to the terminal . IMPORTANT: respect the polarity with 24 Vdc power supply;
e. Use a 22mm commercial spanner to secure the cable gland (3) , ensuring the product has a protection rating of IP65;
f. Secure the cover (2) with the 4 fastening screws (1). Make sure to place the rubber sealing gasket (33) correctly in
order to ensure product rating of IP65;
• The valve needs to be earthed either through the pipe or through other means (ex. cable jumpers).
