2.1 Intended Use

The SMA Com Gateway is a media and protocol converter that integrates PV systems and
components connected with each other via RS485 into the SMA Speedwire network.

In connection with a SMA data logger, the SMA Com Gateway must be operated with Speedwire
(e.g. SMA Data Manager M, SMAClusterController). The system data of all detected RS485
devices is forwarded from SMA Com Gateway via Speedwire to the SMA data logger. At the
same time, the SMA Com Gateway supports communication with up to 50 RS485 devices.

The USB interface of the SMA Com Gateway may only be used for firmware updates.
The product is designed for indoor use only.
All components must remain within their permitted operating ranges and their installation

requirements at all times.
Use this product only in accordance with the information provided in the enclosed documentation

and with the locally applicable laws, regulations, standards and directives. Any other application
may cause personal injury or property damage.

Alterations to the product, e.g. changes or modifications, are only permitted with the express written
permission of SMA Solar Technology AG. Unauthorized alterations will void guarantee and
warranty claims and in most cases terminate the operating license. SMA Solar Technology AG
shall not be held liable for any damage caused by such changes.

Any use of the product other than that described in the Intended Use section does not qualify as the
intended use.

The enclosed documentation is an integral part of this product. Keep the documentation in a

2 Safety

SMA Solar Technology AG

Installation Manual COMGW-10-IA-en-13 9

WARNING

Danger to life due to electric shock

Under fault conditions, when working on the power supply circuit there may be dangerous
voltages present on the product.

• With permanently connected power supply units, ensure that there is a disconnection unit
(e.g. circuit breaker) present outside of the power supply unit.

• With pluggable power supply units, ensure that the outlet for the power supply unit is close
to the power supply unit.

• The disconnect unit and the outlet for the power supply unit must be freely accessible at all
times.

WARNING

Danger to life due to electric shock from touching a damaged or open power
supply unit

Lethal voltages are present in the conductive parts inside the power supply unit. Touching a
damaged or open power supply unit can cause a lethal electric shock.

• Only use the power supply unit indoors and in a dry environment; keep it away from liquids.

• If the enclosure or the power supply unit cable is damaged, disconnect the connection point
from voltage sources. Replace the power supply unit with a suitable new power supply unit.

• Never open the power supply unit.

WARNING

Danger of fire due to incorrect installation

• Have the product mounted, installed and commissioned only by qualified persons with the
appropriate skills.

• Never open the product.

NOTICE

Damage to the product due to moisture

The product is not splash-proof. Moisture can penetrate the product and damage it.

• Only use the product in a dry, indoor environment.

NOTICE

Damage to the product due to condensation
