The enclosure houses the system components
for the weather station. The wiring inside the enclosure is done at Vaisala.
Install the enclosure so that the bottom
comes roughly 1 m (3 ft 3 in) from the ground which is eye height for best working access.
| Before installing the
enclosure, ensure that all sensors are already installed. |
See the relevant instructions:
For the installation weight, see the appendix.
| WARNING The enclosure unit is heavy and contains sensitive equipment.
Exercise caution when mounting the enclosure to avoid personnel injury and damage to
the enclosure. |
| WARNING For safety reasons,
do not install the enclosure alone. Safe installation requires at least
2 people. |
| WARNING A long cable between units
(sensors, transmitters, power supplies, and displays) can cause a lethal lightning-induced
current surge. Always ground the enclosure to a suitable grounded location with a short,
low-resistance cable. |
| WARNING When installing the
backplate without the enclosure, ground the backplate to the local grounding connector with a
low impedance connection. Vaisala recommends 6 mm2 (10 AWG) or heavier copper
wire. |
| To prevent corrosion,
oxidation, and seizing, use a non‑conductive, non‑water‑soluble, non‑silicone‑based
grease, such as ceramic or Teflon paste, between different kinds of metal. |
