2.1.3 Intended Use
The EnOcean RS-485 Gateway 750-940 is used as a gateway for digital and
analog signals from EnOcean actuators and sensors.
The product is designed for a work setting that meets the criterion of protection
type IP 30 (only front side). Protection against finger injury and solid impurities
≥2.5 mm diameter is ensured; protection against water damage is not ensured.
Unless otherwise specified, operation of the components in wet and dusty
environments is prohibited.
Use without additional protective measures in environments within which dust,
corrosive fumes, gases or ionized radiation can occur is considered improper
use.
The EnOcean Gateway must not be used in any relation with equipment that
supports, directly or indirectly, human health or life or with applications that can
result in danger for people, animals or real value.
Emergency stop functions and equipment must not be made ineffective. Please
note the relevant standards; e.g., DIN EN 418.

The EnOcean RS-485 Gateway 750-940 is used to integrate radio sensors into
intelligent controllers and other bus systems per ISO/IEC 14543-3-1x; e.g., to
operation, control and reporting systems in building automation and to cabinet
automation systems aboard ships; it enables creation of wireless, maintenance-
free control solutions.
The module meets the standard EN 61000-6-3.
Observe intended use.
The EnOcean RS-485 Gateway 750-940 must not be used in any relation with
equipment that supports, directly or indirectly, human health or life or with
applications that can result in danger for people, animals or real value.
This arises from the module's ranking as Class 2 Equipment per ETSI EN 301
489-3 V2.1.1 (2019-03) “Specific conditions for short-range devices (SRD).”
Observe statutory provisions for operating frequency range.
The EnOcean RS-485 Gateway 750-940 868 MHz must only be operated in
compliance with the country-specific provisions regarding operation of radio
equipment.
3 modes can be configured on the EnOcean Gateway with the DIP switch to suit
a range of different applications:
• ESP3 mode:
The module functions as a gateway and is connected with a remote station
through the RS-485 interface. Communication is through a 1:1 connection
with the remote station by means of native ESP3 telegrams.
• Modbus®mode:
The module functions as a Modbus slave; it is connected to the Modbus
through the RS-485 interface. Communication with a Modbus master is
performed via the Modbus protocol. Up to ten EnOcean Gateways can be
connected in a series to a Modbus line (daisy chain topology).
• EnOcean Repeater:
The module functions as a repeater amplify and forward radio signals in an
EnOcean network.
The radio transmission can be selected as through the internal module antenna
or through a connected external antenna. The antenna is selected with a DIP
switch; see Section “Operating Elements.”
In Modbus mode, the termination for the last module is switched on by default.
Switching on and off is performed with a DIP switch; see Section “Operation

Elements.” In ESP3 mode, the termination is always switched on, in Repeater
mode it is always switched off, regardless of the DIP switch position.
A BIAS network can by switched on and off with a DIP switch; see Section
“Operation Elements.”
The EnOcean Gateway supports the “SMART ACK” functionality.
An LED indicates the operation status of the mode; see Section “Display
Elements.”
The EnOcean Gateway is designed for mounting on a wall, ceiling or any other
stable, level weight-bearing surface, as well as on a DIN-rail.
A non-conductive mounting surface is necessary when internal antenna is
used.
If the internal antenna is used, ensure the EnOcean Gateway is mounted on a
non-conductive surface.
If it is not, performance may be adversely affected.
