Installation Guide
On-site installation procedure PV monitoring with Xemex KWHIQ meter
The kwhiq meter is equipped with terminal connectors that allow the use of wires with a section
of 2.5 to 25 mm2. If a solid cable is not used, the correct cable ferrules must be fitted. The terminal
connectors are fitted with M7 x 13 cross-head and slotted-head screws that must be tightened with a
Posidriv PZ No. 2 screwdriver to a torque of at least 3.5Nm.
The 1-phase meter is connected with side of mains or meter box to L (terminal l) and N (terminal 4).
See also the diagram on the inside of the terminal cover.
Important:
if the connection of the meter box and solar panels is reversed, the solar panels will work
but the monitoring will not! You can check whether the meter is correctly connected by looking at
the display. This must be done with a working installation: there must be PV production. The display
shows an arrow on the right with -P as caption. It must point to the LEFT.
Fit the terminal cover. On the underside, the correct routing can be cut out for the cable.
