2 Safety instructions
Please observe the following general safety instruc-
tions when installing and operating the device:
- Only a trained electrician, in particular for
the cabling of enclosures with mains power,
may perform assembly and installation of
the PSM busbar. Other tasks associated
with the PSM, such as the assembly and in-
stallation of system components with tested
standard connectors, and the operation and
configuration of the PSM modules may be
performed only by instructed personnel.
- Observe the applicable regulations govern-
ing electrical installations of the country in
which the device is installed and operated
as well as national regulations for accident
prevention. Also observe company regula-
tions (labour, operating and safety regula-
tions).
- Before performing any cabling work on the
PSM system, it must be disconnected from
the mains and secured against reactivation.
- Use only genuine or recommended parts
and accessories (see Chapter 3.5
Accessories). The use of other parts can
void the liability for any resulting conse-
quences.
- Do not make any changes to the PSM sys-
tem other than those described in these in-
structions or associated instructions.
- Operational reliability of the device is only
guaranteed when used as intended. Under
no circumstances may the tolerances speci-
fied in the technical specifications (see
Chapter 12 Technical specifications) be ex-
ceeded. This applies in particular to the
permissible ambient temperature range and
permitted IP protection category. When
used with a higher required IP protection
category, the Rittal PSM system must be in-
stalled in a housing or enclosure with a
higher IP protection category.
- Operating the PSM system when it is in di-
rect contact with water, corrosive sub-
stances or flammable gases and vapours is
prohibited.
- In addition to these safety instructions, it is
imperative that the special safety instruc-
tions mentioned for the individual activities

3 Device description
The PSM is a modular power distribution system
that can be snapped into a PSM busbar as appro-
priate for the requirements. The PSM modules are
available in several variants. All modules described
in these instructions can be monitored and adminis-
tered in conjunction with the Rittal CMC-TC. The
individual socket inserts can be switched for each
module. Because all plug connections are shock-
hazard protected, the assembly and disassembly
work does not need to be performed by a trained
electrician.
3.1 Enclosure
Fig. 1 PSM module, front side
The PSM module is installed in its own aluminium
housing. Catches on the outside edges are used to
snap into the preinstalled PSM busbar. Each of the
equipment slots located on the front side is stan-
dardised and made of plastic. The PSM module has
a dual 7-segment display on the front side. When
this is connected to the Rittal CMC-TC PU II or the
external power pack (DK 7201.210), the currently
consumed power of the complete module will be
displayed. To monitor the individual slots, each of
these is equipped with two LEDs that show the po-
wer currently being consumed at the slot. The LEDs
can change between the colours green, orange and
red. The associated limit values can be freely con-
figured using the CMC. The front side also contains
two LEDs that indicate the current electric circuit on
which the PSM module is being operated.
Fig. 2 PSM module, rear side
Various power supply sockets are located on the
rear side of the PSM module. The PSM module will
be supplied with power when it is snapped into the
PSM busbar.
3.2 Power supply
The module will be supplied with power when it is
snapped into the PSM busbar. All slots are activated
as factory setting. To connect equipment, use the
appropriate connection cable described in Chapter
3.5 Accessories.
Power is supplied to the 7-segment display either at
the connection to the CMC-TC PU II or from an
external power pack (DK 7201.210). A country-
specific connection cable is required when the po-
wer pack is used (see Chapter 3.5 Accessories).
3.3 Network properties
The connection of an RJ45 network cable to the
Processing Unit allows the PSM module to be ad-
ministered and monitored via a network. Read the
CMC-TC PU II operating instructions for details how
this is done.
The following values can be monitored and adminis-
tered:
- Activation and deactivation of the slots
- Set the lower current limit value for alarming
- Set the upper current limit value for alarm-
ing
- Fetch the current power consumption
- Set the limit values of the 3-colour LED
power display (green, orange, red)
- Status of the PSM module
- Electric circuit connection (electric circuit 1
or 2)
- Time-controlled activation and deactivation
(e.g. reboot the connected equipment)
- Create switching combinations (e.g. various
slots will be deactivated in case of a tem-
perature alarm)
- Forward alarm to an SNMP, SMS or e-mail
recipient

connection of the Processing Unit II. Only
modules of the same type can be cas-
caded. For modules of different types, use
different connections of the Processing
Unit II.
7.3 Configuring the display (CMC-TC
operation)
The PSM module has an integrated position sensor.
This is responsible for the correct reading type of
the display. The position sensor is activated as fac-
tory setting. This means when the PSM module is
turned in the PSM busbar (to electric circuit 2), the
display is not up but rather down. The display is
turned automatically so that the values can be read
optimally.
If the PSM busbar with the PSM modules is moun-
ted in the raised floor, the position sensor does not
know how the display should be. It is the same for
the horizontal installation of the PCU (7200.001) in
the 19" level.
To predefine the position of the display, proceed as
follows.
Press the button for three seconds. An "L" will ap-
pear in the display.
Press the button briefly twice until a small rectangle
appears.
Press the button again for three seconds until the
digit "3" appears in the display.
Press the button briefly to select the position of the
display.
•Digit “1”: If the PSM module with the display
is mounted at the top (the black arrow on
the PSM module points up).
•Digit “2”: If the PSM module with the display
is mounted at the bottom (the red arrow on
the PSM module points up).
•Digit “3”: Position sensor is activated (auto-
matic display position).
Press the button for three seconds to save the cur-
rent limit value. A "CL" will appear in the display.
Wait a few seconds until the display changes in the
status display (actual current value).
7.4 Resetting the PSM module to the
factory setting (CMC-TC operation)
You can reset the PSM module to the factory set-
ting. All settings, such as current limit values, ad-
dresses and position sensor, will be lost. Proceed as
follows.
Press the button (1) on the PSM module for three
seconds. An "L" will appear in the display.
Then press the button four times briefly. A flashing
"CL" will appear in the display.
Now press the button for three seconds. The display
will clear for a few seconds and then show the ac-
tual current value.
Reconfigure the PSM module.
7.5 Defining the PSM module on the
CMC-TC PU II (CMC-TC operation)
When power is present at the PSM module and an
address has been assigned, it will be detected au-
tomatically by the CMC-TC PU II.

8.2 Individual current measurement
The PSM/PCU bars have their own current meas-
urement for each switch output.
The two LEDs integrated in the associated sockets
indicate the status of the switch output:
- LEDs off: Relay output switched off
- LEDs flashing green: Relay output switched on /
'Low' current limit value undershot
- LEDs green: Relay output switched on / current
consumption 'OK'
- LEDs orange: Relay output switched on / 'Warn-
ing' current limit value overshot
- LEDs red: Relay output switched on / 'High' cur-
rent limit value overshot
Figure 17 shows an example overview page with
three installed modules in various installation posi-
tions.
Switched on relay outputs are also shown blue on
the web page.
The individual currents of the individual relay out-
puts are shown as Tooltip when the mouse cursor is
moved over the associated socket symbol.
Fig. 17 Overview page
An orange LED indicates a 'warning' at relay output
1/5. The red LEDs indicate that relay output 3/3 has
an alarm (overcurrent).
8.2.1Setup settings
Ten sensor values, ten output values and ten meas-
ured values can be configured for each connected
module.
Ten tabs can be selected for each module, where
tabs 1 – 8 concern the settings for each individual
port, tab 9 concerns the settings for the current
measurement and tab 10 concerns the positioning
or the orientation of the module in the PSM busbar.
8.2.2Equipment settings
Tabs 1..8 are used to display or set the eight (or six)
current measurement values of a module.
These pages can be used to set the delay value of
the output. This delay value acts only when the out-
put is switched off, i.e. this output will be switched
on again after the delay time has expired.
The 'Combinations' button can be used to set the
links for each relay output.
'Switch Output' can be used to switch the relay out-
put.
Figures 18 to 20 show examples of the relay outputs
in various states.
