3.5 SERIAL CONSOLE INTERFACE (RS-232)
The DM4170 switch has a console port for local management. The console port uses an
RJ45 connector. A cable with a male RJ45 connector and a female DB9 connector must
be used for the connection to a computer or laptop.
The serial console cable is an accessory included in the DM4170. Additional cables can
be purchased separately via code 710.0137.xx or assembled as described in the
following images. The pin assignment of the RJ45 connector and its match with the DB9
connector is described in table 4.

3.10ALARM INPUT AND OUTPUT
The DM4170 has two alarm inputs and one alarm output in an RJ45 connector. Alarm 1
and 2 inputs are isolated via optocoupler. External alarm detection occurs when the
voltage difference between IN+ and IN- reaches 12V. Table 10 presents the voltages
and status for alarm 1 and 2 inputs.

Table 9 –Conditions for alarm detection
For alarm output, the equipment uses a relay. In an alarm situation

or when the switch
is off, pin 7 (common) is short circuited with pin 8 (NC). When operating without alarms,
pin 7 (common) will be short circuited with pin 6 (NO), while pin 8 (NC) will be isolated.

DM4170 switches have two PSU 125 power supply slots (supplied separately) on
the front of the switch.

Roadmap feature, contact TECHNICAL SUPPORT if you have any questions.

DM4170 –Instalation Guide
HARDWARE DESCRIPTION
204.0302.05 –February/2021

The DM4170 switches have two PSU models: the PSU 125 DC that operates with
DC -48/60 Vdc power supply and the PSU 125 AC that operates with 100/240Vac
(50/60Hz) AC power supply. For further details read the TECHNICAL
SPECIFICATIONS chapter.
The PSU 125 DC has TERMINAL BLOCK power terminals; the terminals are located
on the front of the PSU.
The PSU 125 AC has three-pin IEC 320/C14 plugin power terminals; each terminal
being responsible for supplying power to each of the power sources.
The PSU 125 power sources operate in 1:1 redundancy, with only one of them
being sufficient to maintain the switch’s full operation. The combination of AC
and DC power sources on the same switch is permitted. The insertion/removal of
the power cables and the PSU 125 can be hot-swapped allowing the
uninterrupted operation of the switch if one of the two power sources is turned
off or fails. The PSU 125 has a PWR LED on its front panel which, when lit,
indicates that it is properly powered and operational.
Figure 11 - PSU Panel 125 DC
Figure 12 - PSU Panel 125 AC
The equipment is de-energized through its power cable (s). The power
outlet must be nearby and easily accessible.
The electrical installation of the site should be protected by devices
against short circuits.

DM4170 –Instalation Guide
HARDWARE DESCRIPTION
204.0302.05 –February/2021
19
On the PSU 125 DC, fuses F1 and F2 support currents up to 15A. They
are 86V Fast Acting. If necessary, only replace it with one of the same
specifications. The F3 output fuse supports currents up to 15A. It is
also 86V Fast Acting. If necessary, also replace it with another one
with the same specifications.
In the PSU 125 AC, fuse F1 supports currents of up to 5A. They are of
Fast Acting type, 250V. If necessary, only replace it with one of the
same specifications. The F1000 output fuse supports up to 15A. It is a
Fast Acting type, 86V. If necessary, also replace it with another one
with the same specifications.
In the situation where both PSUs are present and the power inputs are
energized and operating with voltages within the specified range, the
main power input (MAIN) will take precedence over the BACKUP power
supply.
3.11.1 Pin Settings and Polarity
3.11.1.1 PSU 125 AC
The figure below presents the pin assignment of the IEC 320/C14 connector for the power supply of the
equipment.
Figure 13 –AC Power Connector Pin Assignment
According to the NBR 14136 standard, the grounding pin of the
product must be connected to the grounding installations of the
installation site, since the power pins have no polarity indication.

3.11.1.2 PSU 125 DC
The figure below shows the pinout of the TERMINAL BLOCK connector for powering the
equipment.
Figure 14 –DC Power Connector Pin Settings
3.11.2 Power Cables
3.11.2.1 PSU 125 AC
The PSU 125 AC includes a 3-meter power cord in the standard female IEC 320/C14 for
the NBR 14136 plug.
3.11.2.2 PSU 125 DC
The PSU 125 includes a 3.5 meter DC power cable in the PP 1 mm2 gauge standard
with both ends open and the TERMINAL BLOCK standard male connector (normally
shipped screwed to the PSU 125 DC) for the installation of the cable.
Follow the information below to install the cable to the Terminal Block connector:
Step 1
Remove the TERMINAL BLOCK connector from the PSU 125 DC by
unscrewing the two side screws of the connector using a 1/8"
screwdriver (number 0) as shown below:
