Chapter Two INSTALLATION
2.1 General
The 605M-D1 module is housed in an rugged aluminium case, suitable for DIN-rail mounting..
All connections to the module must be SELV. Normal 110-250V mains supply should not be connected to any
terminal of the 605M-R1 module. Refer to Section 2.2 Power Supply.
Before installing a new system, it is preferable to bench test the complete system. Configuration problems are
easier to recognize when the system units are adjacent.
The foldout sheet 605M-D1 Installation Guide provides an installation drawing appropriate to most applications.
Further information is detailed below.
Each 605M-D1 module should be effectively earthed via the "GND" terminal on the 605M-D1 module - this is to
ensure that the surge protection circuits inside the 605M-R1 module are effective.
2.2 Power Supply
The 605M-R1 module can be powered from a 12 - 24VDC power supply. The positive side of the supply must not be
connected to earth. The supply negative is connected to the unit case internally. The DC supply may be a floating
supply or negatively grounded.
The power requirements of the 605M-R1 unit are 1200mA @ 12V or 900mA @
24VDC.
Power connection is made by the included cable. Connect the Green “GND” and
Black “GND / A” wires to the supply negative, and connect the Red “POWER+”
to the supply positive.
The white “SENSE / B” wire is available for sensing modem connection status,
but is not required for power supply connection.
