ATTENTION!
Damage to the Sunny SensorBox due to liquids entering in.
• When working outdoors, make sure that no liquids (e.g. rain or snow) enter the open
Sunny SensorBox.
• When inserting and removing the cable
through the cable gland, make sure that
the grommet fits correctly into the cable
gland.
ATTENTION!
Damage to the Sunny SensorBox due to porous rubber seals
The rubber seal in the Sunny SensorBox lid becomes porous over time and will no longer
provide a tight seal if the Sunny SensorBox is opened. If you open the Sunny SensorBox
after an operating lifetime of more than 5 years, e.g. for upgrading the device, the rubber
seal in the Sunny SensorBox lid must be replaced with a new one. In this instance please
order a replacement seal before starting maintenance works.
