Wiring Using The 8-Pin M12 Connector With Independent Cabling For Heating
The wiring example provided below at Figure 1 is recommended for most installations, providing a
separate cabling run of high quality cable for the Vaisala device heating current (if required). The pin
connections for the 8-Pin M12 and wire colours are listed in Table 1 on page 7.
For installations that do require the optional heating accessory, ensure a high capacity cable
between the DC Power supply and the Vaisala device is used.

The 8-Pin M12 connector is located on the bottom of the Vaisala device.
NOTE
The 16mm

Copper Cable to Earth Ground cable is a critical component for the correct operation of the surge protector.
Ensure this is installed correctly.
