Installing Enclosure
The stainless steel electronics enclosure houses the QML logger,

the customer needs to do the following mechanical installations:
- Mount the enclosure to a mast or on a wall.
- Mount the backup batteries inside the enclosure.
- Insert the SIM card to the GMS/GPRS modem inside the enclosure, if
GSM/GPRS telemetry is used.

The radiation shield is preinstalled at Vaisala to protect the enclosure in
mast installations. The radiation shield can be removed for the
