9.5 Care
Use a soft and moist cloth to clean the Sunny SensorBox and the RS485 Power Injector or SMA Power
Injector with Bluetooth. Make sure the cloth is made of scratch-free material so as to avoid damaging
the surface of the enclosure. If there is a considerable amount of dirt, you can also use a mild, non-
abrasive and non-corrosive cleaning agent.
NOTICE!
Damage to Sunny SensorBox from water seeping in.
Tightening the cable gland may cause the gasket ring to become damaged or loose its
proper threading position in the cable gland. The Sunny SensorBox will no longer be
watertight as a result.
• Make sure the gasket ring is seated properly.
