The requirements of the Low Voltage Directive must be observed for the wiring of
the Relay Module 4/8 Ch.
It must be possible to disconnect all mains cables on the Relay Module 4/8 Ch from
the power supply by means of an appropriately marked and easily accessible circuit
breaker (e.g. in a distribution box of the building installation). Dräger recommends
making sure that the 240 V AC cables on the Relay Module 4/8 Ch can be
disconnected from the power supply of the REGARD 3000 power supply unit
separately.

Modbus RTU Gateway Module

Gateway Module to output system data via a fieldbus-specific interface to higher
level systems, such as to a DCS (Distributed Control System) or SCADA
(Supervisory Control and Data Acquisition) system.
The Gateway Module is designed for provision of data for visualisation and
documentation of system behaviour. The module can be used to acknowledge
channels or switch these to the Inhibit status. The evaluation of the transmitted data
for safety switching actions is prohibited.
