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.

This section describes the installation and connection of the RS485 Piggy-Back communication
interface. It is assumed that the inverter is situated in the middle of the RS485 communication bus. If
the inverter is situated at the end of the RS485 communication bus, carry out the following steps for
one cable only and connect the termination (see Page 15).
If the communication interface is preinstalled, you can skip Section 4.2 "Installing the
Communication Interface" (Page 10).

4.2 Installing the Communication Interface
In order to install the communication interface for the SB, WB and SWR inverters mentioned above
proceed as follows:
1. Open the inverter as described in the inverter documentation.
2. In inverters of the SWR type, resistors with a black
ring must be removed before installation. Carefully
cut off the resistors with a black ring using diagonal
cutting pliers.
3. Plug the communication interface (A) to the left of
the interface port. The 2 pins on the right of the short
pin row below stay free.
☑ The communication interface is installed.

4.3 Connecting the Communication Interface
4.3.1 Preparing the Enclosure Opening on the Inverter
Perform the following steps, depending on the inverter model:
• For inverter models with one enclosure opening see Section "Inverter Models with One
Enclosure Opening" (Page 11)
• For inverter models with two enclosure openings see Section "Inverter Models with Two
Enclosure Openings" (Page 11)
Inverter Models with One Enclosure Opening
1. Open the inverter as described in the inverter documentation.
2. Push the filler plug out of the enclosure opening
which is located at the bottom of the inverter.
3. Insert the cable gland with the double seal insert
in to the e ncl osu re open ing of the i nve rter and fasten
it from inside with a nut.
4. Unscrew the nut of the cable gland and push out
the seal insert.
5. Push out the filler plug in the seal insert with a screwdriver depending on the number of cables
to be led through.
☑ The enclosure opening on the inverter is prepared.
Inverter Models with Two Enclosure Openings
1. Open the inverter as described in the inverter documentation.
2. Push out the filler plug at the bottom of the inverter
depending on the number of cables to be led
through.
Installation Guide 485PB-SB-NR-IEN101311 11
Electrical Connection SMA Solar Technology AG
3. Place the cable gland with single seal insert into the
prepared enclosure opening of the inverter and
fasten it with a nut from inside the enclosure.
4. Loosen the nut of the cable gland so that the cable
can be inserted.
☑ The cable opening on the inverter is prepared.
4.3.2 Installing the Cable in the Inverter
The instructions for preparing and installing the shield clamp only apply for SB/WB 3300
and SB/WB 3800 inverter models.
1. If you are using a shield clamp, proceed as follows:
– Measure 4 cm plus the length of one insulating
tube f rom the end of the c able an d strip app rox.
1.5 cm of the cable sleeve down to the shield.
– Apply a conductive bonding sheet around the
stripped area of the cable.
☑ The cable is prepared for the shield clamp.
– Insert the cable into the inverter through the
cable gland.
– Use the screw and the contact disk to fasten the
shield clamp to the screwing device for the
shield clamp on the inverter.
– P ush the s tri pped par t of the cabl e in to the sh iel d
clamp.
☑ The shield clamp is installed.

2. If you are not using a shield clamp, proceed as follows:
– Insert the cable into the enclosure through the cable gland.
– Strip the cable sleeve to match the length of the
cable route (A). The length of the cable route
depends on the inverter model (see images in
Section 4.1 "Overview of Interface Port and
Cable Route" on Page 8).
– Shorten the unused insulated conductors down
to the cable sleeve (C).
– Shorten the cable shield to reach the PE
co nne ctor (co nne cto r ta b) ( B) in the inv ert er a nd
twist it. The length to the PE connector depends
on the inverter model (see images in Section 4.1
"Overview of Interface Port and Cable Route"
on Page 8).
– Connect the flat cable connector to the cable
shield.
– Connect the flat cable connector with the PE
connector tab.
– Strip 6 mm off the insulated conductors (D).
3. Tighten the nut of the cable gland to secure the cable.
4. Installing the insulating tube:
DANGER!
Danger to life through high voltage if there is a fault with the communication
cable.
• Pull an insulating tube over the wires of the used cables that
reaches up to the inverter enclosure opening. The insulating
tube must completely cover the wires inside the enclosure.
• If necessary, cut the insulating tube back to the required
length.
5. For simplification the two cables can be bound together with a cable tie.
6. Install the cable with an insulating tube along the cable route to the screw terminals.
☑ The cable is installed in the inverter.

from the terminal block afterwards.
• Do not use wire sleeves when connecting the communication cable.
1. Connect the wires to the screw terminals (2, 5, 7)
below the interface port (torque: 0.23 Nm).
Write down the colors of each wire:
