Section 7: Installation of Heat and Electricity Meters
Page 27
7.2.7 Connection of mains power supply
The required power supply for the heat meter is factory fitted and
terminated in a 3-way terminal block, located behind the meter
housing when the cover plate is removed. Refer to Figure 7-9.
This power supply is protected by a 1A fuse, located on the control
panel. Refer to Section 14 (Control Panel).
To connect the mains power supply to the integrator unit, use the
following procedure:
1. Unscrew the three terminals; remove the terminal block from
the three wires and discard it.
2. Pierce the cable grommet located in the lower face of the
integrator unit (below terminals L, N and ) and pass the three
wires through.
3. Connect them to the mains power terminals in the lower right
hand corner of the integrator unit, as follows:
•
Black wire – terminal L (Live)
•
Blue wire – terminal N (Neutral)
•
Green/Yellow wire – terminal (Earth)
Refer to Figure 7-12 Integrator connection diagram.
Ensure that the wires are securely held under the metal cable
clamp.
4. Finally, re-fit the front of the integrator unit to the rear section.
Locate the four clips (two on each side of the front section)
into the corresponding openings on the two sides of the rear
section.
5. Carefully push the front onto the to rear section until it clips into
placeards to remove it from the rear section of the unit.
7.2.8 Security seals
Both the integrator and flow meter are supplied with factory-
fitted calibration seals. These are to protect against unauthorised
tampering, manipulation or dismantling of these items that will
invalidate the product guarantee.
These seals are located as follows:
•
Integrator unit - two stickers seals are located on the inner
(rear) face of the front section of the integrator unit. Refer to
Figure 7-14. These calibration seals must not be tampered with
or removed.
•
Flow meter - two seals (one a sticker and the other a wire seal)
are located on the front face of the flow meter. Refer to Figure
7-15.
Following installation of the heat meter, three further user sticker
seals (supplied with the heat meter) should be applied to the
integrator unit, as follows:
•
One user sticker seal must be stuck over the terminal screws
on the flow meter connections (terminals 9, 10 and 11) on the
intregrator terminal block. Refer to Figure 7-16.
•
Once the front section of the integrator unit is finally fitted to the
rear section, two user sticker seals must be stuck over the joint
between the front and rear sections. These two stickers should
be located on the small flat area, on either side of the integrator
unit, intended for this purpose. Refer to Figure 7-17.
