7.1 Information on Starting up the Device
This section shows you how to connect external sensors and start up the Sunny SensorBox with the
RS485 Power Injector or the SMA Power Injector with Bluetooth.
For initial startup, the following steps must be taken:
• Connect the module temperature sensor (see page 36).
• If necessary, connect the anemometer (see page 38).
• If necessary, connect the ambient temperature sensor (see page 39).
• Connect the Sunny SensorBox to the RS485 communication bus via the RS485 Power Injector
and turn it on (see page40) or connect the Sunny SensorBox to the SMA Power Injector with
Bluetooth and turn it on (see page 53).
7.2 Connecting the Module Temperature Sensor
1. Open the Sunny SensorBox (see page 61).
2. Unscrew the cable gland's lock nut on the bottom left
of the Sunny SensorBox and remove the filler plugs.
3. Thread the sensor cable through the lock nut and the
cable gland at the bottom left and into the enclosure
of the Sunny SensorBox and then tighten the cable
gland.
NOTICE!
Damage to the Sunny SensorBox from water seeping in.
• When inserting or removing the cable
through the cable gland, make sure the
gasket is properly seated in the cable
gland.
Cable length when connecting in a 2-conductor technology
The connection is made via a 2.5 m cable. The cable may not be extended or cut. The
