Wiring Using The Screw Terminal Connector With Split Cabling For Heating
The wiring example provided below at Figure 4 is an alternative screw terminal wiring guide,
providing a shared cabling run of suitable high capacity cable for the Vaisala device and heating
accessory (if required). The pin connections for the screw terminal connector and wire colours are
listed in Table 2 on page 10.
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 screw terminal connector can be accessed from the bottom of the Vaisala device by unscrewing the three screws on
the Vaisala device's chassis, and carefully revealing the terminals. Cable runs can be fed through the small pluggable
holes in the base of the unit. Ensure to fully seal the Vaisala device once wiring is complete.

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.
