2.1 Intended Use

The SMA RS485 Module enables SMA inverters to establish wired RS485 communication.
The SMARS485Module enables SMA inverters of type "SBx.x-1SP-US-40" to establish

communication between the inverter and the energy meter according to ANSIC12.20 of the
SMARevenueGradeMeterKit. The SMARS485 module can be used in SMA inverters of type
"SBx.x-1SP-US-40" only to establish this communication. The setup of a cable-connected RS485
communication to other units is not supported.

The product must only be installed in the following SMA inverters:

• STP50-US-40 (SunnyTripowerCORE1-US)

• STP33-US-41 (SunnyTripowerCORE1-US)

• STP50-US-41 (SunnyTripowerCORE1-US)

• STP62-US-41 (SunnyTripowerCORE1-US)

• SB3.0-1SP-US-40 (Sunny Boy 3.0-US)

• SB3.8-1SP-US-40 (Sunny Boy 3.8-US)

• SB5.0-1SP-US-40 (Sunny Boy 5.0-US)

• SB6.0-1SP-US-40 (Sunny Boy 6.0-US)

• SB7.0-1SP-US-40 (Sunny Boy 7.0-US)

• SB7.7-1SP-US-40 (Sunny Boy 7.7-US)
The inverter still complies with the standard after the product has been installed.
All components must remain within their permitted operating ranges and their installation

requirements at all times.
The product is approved for the US and Canadian market.

2.2 IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS
This section contains safety information that must be observed at all times when working on or with

the product.
The product has been designed and tested in accordance with international safety requirements. As

with all electrical or electronical devices, there are residual risks despite careful construction. To
prevent personal injury and property damage and to ensure long-term operation of the product,
read this section carefully and observe all safety information at all times.

DANGER

Danger to life due to electric shock when live components or cables of the
inverter are touched

High voltages are present in the conductive components or cables of the inverter. Touching live
parts and cables of the inverter results in death or lethal injuries due to electric shock.

• Disconnect the inverter from voltage sources and make sure it cannot be reconnected
before working on the device.

• Wear suitable personal protective equipment for all work on the product.

NOTICE

Damage to the enclosure seal in subfreezing conditions

If you open the inverter when temperatures are below freezing, the enclosure seals can be
damaged. This can lead to moisture entering the inverter.

• Only open the inverter if the ambient temperature is not below -5°C (23°F).

• If a layer of ice has formed on the enclosure seal when temperatures are below freezing,
remove it prior to opening the inverter (e.g. by melting the ice with warm air). Observe the
applicable safety regulations.

NOTICE

Damage to the product due to sand, dust and moisture ingress

Sand, dust and moisture penetration can damage the product and impair its functionality.

• Only open the inverter if the humidity is within the thresholds and the environment is free of
sand and dust.

• Do not open the inverter during a dust storm or precipitation.

• Close tightly all enclosure openings.

• Only use listed rain-tight or liquid-tight conduit fittings to attach the conduits to the product.

NOTICE

Damage to the inverter or product due to electrostatic discharge

Touching electronic components can cause damage to or destroy the inverter or the product
through electrostatic discharge.

• Ground yourself before touching any component.
