Properties of the RS485 data line
Recommendation
↻ To prevent interference during data transmission:
- Observe the wire pairing when connecting DATA+ and DATA-.
Do not lay RS485 bus lines in the vicinity of live DC/AC cables.
1 Undo the cable fitting [ W_20]
2 Thread the connection cables through the cable fitting.
3 Fit the ferrite clip on the door beam around the RS485 bus line using a cable tie.
4 Lay the connection cable correctly in the lower AC supply area and loosely
fasten it using the cable ties provided.
5 Open and close the door completely to check that the connection cable is not
subject to tensile or compressive forces.
6 To connect the shield, strip the RS485 data cable from the position of the shield
terminal to the wire mesh (approx. 20 mm).
7 Clip the stripped RS485 data cable into the shield terminal.
8 Connect the connection cables to the corresponding connection terminals.
9 The following must be connected to all inverters and to the data monitor unit in
the same way:
- Wire A (-) to wire A (-) and wire B (+) to wire B (+)
- GND to GND
10 Secure cable ties.
11 Tighten the cable fittings [ W_20 /
NOTE
When using the RS485 bus system, assign a unique address to every bus device (inverter, sensor) and ter-
minate the terminal units (see the "Settings" menu) .
↻ Check whether one of the devices represents the terminal unit.
F Only activate the terminating resistor on the communication circuit board of the terminal unit using the DIP switch.
» RS485 connection made. Lay signal cable correctly.
7.9.5 Connecting external grid protection components
The contact is designed as an N/O contact and is labelled "ERR" or "Relay" on the circuit board.
Maximum contact load
DC 30 V / 1 A
↻ Connection area cover open.
1 Loosen the cable fitting to pass the signal cable through [ W_20]
2 Thread the connection cables through the cable fitting.
3 Attach the connection cables to the terminals.Overview [See section 7.9.1} Page 29]
4 Tighten the cable fitting [ W_20 /
