To supply the voltage measuring module, wire the supply input (P_IN) to the corresponding

supply output on the current measuring module (P_OUT).

Use twisted and shielded cables for all signal and supply cables to avoid electromagnetic

interference from the PV generator (e.g., via the string cables or bus lines). Ground the

shield.

6.7.3 Connecting the measuring module outside of the

SOLARCHECK device family

You can use the voltage measuring module as a simple analog measuring transducer out-

side of the SOLARCHECK device family. For this, connect the signal output

(2 V ... 10 V OUT) to a suitable analog voltage input of an evaluation unit.

Make sure the load does not fall below 10 k.

The cable length between these two devices must not exceed 0.5 m.

In this case, power is not supplied via the SOLARCHECK devices, but is supplied sepa-

rately. For additional details on the design, refer to Section “Design of a separate power sup-

ply for the SCK-M-U-1500V voltage measuring module” on page 62.

Use twisted and shielded cables for all signal and supply cables to avoid electromagnetic

interference from the PV generator (e.g., via the string cables or bus lines). Ground the

shield.
