2.1 Appropriate Usage
The RS485PB-NR and RS485PB-MS-NR communication interfaces make it possible to establish wired
RS485 communication. With these communication interfaces you can configure inverter parameters
with a communication product and view momentary values of the inverter. The following inverter
models are supported by the communication interfaces:
• 485PB-NR suppor ts t he f oll owi ng i nverter mod els : SB /SW R/W B 70 0, S B/SWR/WB 1100(E)
(LV), SB/SWR/WB 1700 (E), SWR 2000, SB 2100TL, SB/SWR/WB 2500, SB/WB 2800i,
SB/SWR/WB 3000, SB/WB 3300, SB/WB 3800.
• 485PB-MS-NR supports the following inverter models: SB 3300TL (HC), SB 4200TL (HC), SB
5000TL (HC) (W).
The communication interfaces (485PB-NR and 485PB-MS-NR) comply with the following standard:
• TIA/EIA-485-A, 1998
The interfaces are provided as an add-on kit or are pre-installed in the inverter.

2.2 Safety Precautions
DANGER!
Risk of lethal electric shock when opening the inverter.
• All work on the inverter must be carried out exclusively by qualified personnel.
• Disconnect the inverter on the AC and DC sides as described in the inverter manual.
WARNING!
Danger to life through high voltage if the communication cable is not installed
properly.
Install the communication cable separately from the grid connection (AC cable) and also
separately from the signaling contact, if necessary.
NOTICE!
Electrostatic discharges can damage the communication interface.
• Avoid coming into contact with components' connections and plug contacts.
• Ground yourself before touching the communication interface by touching the
protective conductor (PE) or a non-coated part of the inverter housing.
NOTICE!
Metal or cable scraps in the housing can damage the inverter.
• Make sure that no metal scraps of the cable shield or the cable fall into the open
inverter when working on the cable.
• Remove any metal or cable scraps, if necessary.
