Schleifenbauer PDU
TESTING
Each Schleifenbauer PDU is individually tested according to the NEN 3140 standard. Test reports are available on request.
CLEANING
The PDU may only be cleaned by wiping off the outside with a clean dry cloth.
CONTENTS OF THE PACKAGE
The Schleifenbauer Intelligent PDUs are shipped in a cardboard box. Where applicable, dispose the packaging material in a
responsible manner, in accordance with local regulations. All of the materials used for packaging can be recycled.
Immediately after receipt, check whether you have received your order in a complete and undamaged state.
The following items are delivered for each PDU:
●fixing materials: these can be attached to the PDU (19’’ or table-mounting brackets), or are delivered separately if
they have been ordered separately;
●the installation manual (one per shipment);
Please note that the PDU User Manual can also be found online at http://schleifenbauer.eu
ADDITIONALLY NEEDED TOOLS FOR INSTALLATION
The following tools are needed to install the PDUs:
●cage-nuts with bolts and washers
●suitable screwdriver.
MOUNTING THE PDU IN CABINETS
How to mount a PDU horizontally (19 inch)?
Each 19’’ rack bracket of a PDU has holes for horizontal mounting in 19” racks. The holes are
positioned so that an appropriate fixing hole is always available for a PDU with a profile height of
1.5 U. Using one or two of the four holes allows mounting without wasting space.
For measurement of insulation resistance, the measuring voltage used must be lower than or equal to the
voltage according to the product specification.
Page 9 of 58
V262_User manual
Schleifenbauer PDU
How to mount a PDU vertically (= 0U)?
In case of a PDU for vertical mounting, the connection lead is fed through a hole in the upper, bottom or front face.
How to install on a flat surface? Table top mount
Gives the profile possibility to be mounted to a flat surface (tabletop).This
arrangement is used for:
●vertical mounting to the bracing beams in the 19” cabinet
●fixing to a mounting plate
●mounting between the 19” uprights: the profile attaches to the front
of the uprights
The holes on the brackets are located as far as possible to the outside so
that it can also fit with enough space to tighten the bolts if a swivel gland
has been placed on the short side.
How to prevent hot spots in a cabinet? Sunken
installation
When power leads might block the flow of hot exhaust air, especially in
case of a 600mm wide cabinet, it is necessary to create additional space
for airflow. This can be done by using the “sunken installation brackets”.
Because of the shape of the bracket, it is possible to ‘partially sink’ the
profile into the cabinet and save space. These mounting plates can be
used for many different cabinets.
How to mount a PDU without tools?
Toolless mounting is created by making attachment points on the rear of
the PDU housing. There is a wide range of cabinet brackets available, all in
which you can hang the PDU without using tools.
Toolless Mounting can be done as single PDU or double PDUs (see image).
Mounting brackets can be custom made by Schleifenbauer.
How to achieve maximum mounting flexibility?
Mounting with profile clamps
The clamps, made of spring steel, can be installed in the position of your
choice. The clamp fits around the PDU profile and is secured with a
fastening screw. Our advice is to use one clamp for every 50 cm of profile
length.

Schleifenbauer PDU
CABLING THE PDU: ETHERNET, DATABUS AND SENSORS
How to connect the PDU to LAN?
10/100 Mbps LAN Ethernet port
Connecting the PDU to a Local Area Network (LAN) provides
communication through an Ethernet network. Multiple PDUs can share
the same ethernet connection by using the databus (Bridge or Hybrid
mode). More about the different operating modes in the section
“Schleifenbauer databus, what is it?” The RJ45 connector for the network
cable must be plugged into the silver Ethernet port:
Connect the RJ45 Ethernet cable to the Ethernet port on the PDU and to
the Ethernet connector on the LAN device; when connected, the orange
LED – marked “lnk” - will blink
How to connect a databus?
There are three black communication ports. One is marked as sensorport,
the other two as databus ports (in and out). The left databus port is the
“incoming” databus port. The right databus port is “outgoing”. This is a
MUST HAVE for devices in bridge mode. For devices in hybrid mode it is a
NICE TO HAVE. The serial databus in the Schleifenbauer PDU uses CAT5
patch cables.
Data will be send and received by both ports but to close the
databus ring, it is recommended to follow the connection diagram to
ensure maximum performance.
How to connect sensors to a PDU?
The PDU has a RJ12 connector sensor port which can connect one of the
following:
●a digital temperature sensor
●a combined sensor for temperature/humidity
●one or multiple dry switch contacts
Plug and play
Sensors are automatically recognized by the PDU and will update the
display and menu accordingly.
Use Schleifenbauer sensors only

V262_User manual
Schleifenbauer PDU
How to connect a NO/NC contact on Classic PDU and ethernet PDU?
The sensor port makes use of the RJ12 6P6C standard (= 6 position, 6 conductor). To connect a NO/NC contact on the PDU
sensor port, you have to make use of pin 1 and pin 6 ; as shown in the image below.
How to connect NO/NC contact on a G3 PDU?
3rd generation PDUs and DPMs are equipped with a USB-port and are able to operate two NO/NC dry switch contacts:
Note that on a PDU only 1 NO/NC contact can be connected.
Status of the contact will be displayed. The state cannot be changed locally.
Classic PDUs (= without ethernet port) do not support a NO/NC contact

PART II - USER MANUAL
How to maintain a PDU?
A Schleifenbauer Intelligent PDU may not be opened by unauthorized personnel. In the event of malfunction or faults in
the PDU, please refer to the warranty conditions. Schleifenbauer Products BV will not accept warranty claims if the PDU
has been opened or alterations have been made.
●Please pay attention to the operation conditions before installation and operation of the Schleifenbauer PDU.
●The Schleifenbauer PDU has to be protected according to the valid installation guidelines.
The rated value of the in-series protective device may not exceed the maximum value indicated on the product.
●The Schleifenbauer PDU may not be used in: a humid environment, a seriously contaminated environment or
outdoors.
●The manufacturer’s warranty on the Schleifenbauer PDU becomes invalid when the QC sticker on the side of the
profile is broken.
●Before turning on the PDU for the first time, make sure that it has been allowed to acclimatize to the ambient
temperature for at least 24 hours. Major temperature fluctuations can lead to the formation of condensation in the
PDU if this guideline is not followed.
●Please keep in mind that the maximum allowed temperature for a metal enclosure is 70 °C for installation in a
normal location and 90 °C for installation in a restricted access location.
How to be sure the status of switchable outlets will not change during firmware
upgrade or restarting of the controller?
The Schleifenbauer PDUs are designed for continuous operation with the power distribution and the control over
measuring and switching separated. This means that while updating or restarting the (controller of the) PDUs, power
distribution is not interrupted.
LIFE-SUPPORTING POLICY
The Schleifenbauer PDU has been designed for use in data centers where equipment has to meet very high demands
especially regarding reliability.
The Intelligent PDU however may not be applied in surroundings where a malfunction in the PDU can have consequences
for life support systems.
Life support systems include any devices designated as “critical” by the U.S. FDA. Such systems are found not only in
medical environments such as hospitals, but also on offshore platforms, in petrochemical plants, in air traffic control
centers, etc.

Schleifenbauer PDU
PART IIA - LOCALLY MONITORING: DEVICE DISPLAY
The intelligent PDU features a display with scroll buttons, LEDs and some ports for connecting accessories. Please keep in
mind that PDUs may differ in configuration and may or may not not have a display.
(1) PDUs without an Ethernet port are called Classic PDUs. Firmware for Classic PDUs are in the FW1xxx - range
(2) This option is called “Local alert reset” and must be activated through the interfaces
(3) USB-port on g3 (generation 3) only ; to be used for firmware up- and downgrade (from FW2.52 and newer)
How to change settings locally via PDU display?
Changing settings locally via the PDU itself is not possible! You have to use one of the interfaces.
See the Administrator part of this manual how to changes the settings
Page 14 of 58
V262_User manual
Schleifenbauer PDU
How to stop a blinking display? Local alert reset
Since FW2.50 alerts are represented on both display and web interface. For example:
The displayed text shows directly which alert has occurred.
Why do alerts occur?
Alerts are signal flags after an event occurred. For example, if the measured temperature and the environmental
conditions exceed a configured level or threshold, the PDU will generate an alert. This resolves in:
●SNMP trap (optional).
●The screen of the PDU will start blinking.
●The screen of the PDU will jump to the Alert page which provides information on what happened.
After the temperature has dropped again, the event is cleared but the alert still exists. The display will blink until you
“reset” (=clear) the alert.
The LCD display only flashes when an alert is active.
How to check the load balance, the temperature / humidity or the status of the
NO/NC contact?
Actions:
●press any button to stop blinking for a short period: blinking will stop so you can read the display
●resetting the alert can be done by pressing both scroll buttons simultaneously; when cleared the
display will stop blinking (Note: this possibility must be activated on your device; see Admin part of
this manual)
You can reset the alert but by doing so, you do not resolve the cause of the alert!
If the alert condition is still present the alert will reappear.
The image shows three phases (L1, 2 and 3). The actual information is presented in
amperes but is also graphically displayed. The higher the load, the more the bar is
filled. The graphical bar is related to the maximum PDU rating (in the image it is 32A).
In this image, there is almost zero load, only on L3 there is a small 0.1A.
DS = status of NO/NC contact [ O = open; C = closed ]
Te = temperature [degrees C] *
RH = relative humidity [%] *
*only visible when the corresponding sensor has been connected.

How to get back to the first page?
How to check an outlet status locally?
How to check input and/or outlet measurements?
If there are alerts, first clear these by pressing both scroll buttons (see: “How to stop
blinking display? Local alert reset” ).
If the alerts are resolved or there are no alerts (no blinking display), press both scroll
buttons (see arrows in image) to quickly jump to the first page.
Note: every row on the display shows the
state of nine outlets. So the first ends with
outlet nine, the second row starts with
outlet ten.
In the “outlets” display you can see how many outlets the PDU has and what their
individual state is.
An overview of the possible states:
0 = off
1 = on
s = scheduled to go off
S = scheduled to go ON
p = power cycling
Example: input page
Note: “Input x” shows the name of the
Input. This information can be configured
from the Web Interface, Inputs tab or from
the other interfaces.
Example: outlet page
The scroll buttons allow the user to scroll through the pages. The total amount of
pages varies and depends on the PDU configuration. For example: the more
outlets the higher the total amount of pages. In the “input page” example page
four of 29 is displayed. In the lower left corner of the “input page” example, the
subject of the shown information on this page is visible as "INPUT L2", which is
short for input measurements of L2. So, when you search for outlets, scroll
through the pages until the “outlet” sections are reached. An example is shown in
the "outlet page" image.
Displayed information can be:
I = current [A]
P = power [W]
U = voltage [V]
Pf = power factor [%] (= real power ÷ apparent power)
Et = energy total [kW]
Es = subtotal energy [kW]

V262_User manual
Schleifenbauer PDU
How to read Branch Residual Current measurements?
In parts of Europe, electrical installations must incorporate devices designed to protect people and prevent fires: the
residual current device, or RCD. A RCD disconnects the circuit if the total for the incoming and outgoing currents in the
monitored phases and their neutral conductor exceed a threshold, for example : L1 + L2 + L3 + N > 30 mA
Data center practice: Residual Current Monitoring in relation to Residual Current Devices
Many devices inside a datacenter operate a switching power supply. These power supplies usually leak a bit of energy to
the protective earth, so even without failing hardware some residual current will occur. In order to rule out a single
dangerous fault from a sum of harmless smaller faults, one needs to set up a network of RC-sensors and monitor them
permanently. RC-monitoring can take place in many forms. The Schleifenbauer RC-sensor offers Class B metering, thus
enabling our customers to set-up an RC-monitoring system that prevents dangerous situations inside the datacenter.
Where to measure residual current?
When monitoring residual current at a single location it is not possible to determine whether the measured value is a sum
of many small currents or a single larger (dangerous) one. For that reason it contributes to the safety of the personnel
inside a data center when residual currents are metered at several points.
How to find the PDUs unit address, tag, name or location?
L1 + L2 + L3 + N > 0 mA …. THERE MIGHT BE FAULT IN YOUR SYSTEM !
When the PDU is equipped with a Residual Current Sensor (RCS), measurements of
the residual current are shown in the sensor pages.
(See example images in the previous chapter “
Option 2: sensor pages
”
).
The device name and tag can be
changed using the WEBAPI. See
the admin manual Part IIB -
Remote operating and
monitoring: Web interface for
more details.
You will find all customer specific information about the PDU in the “Custom”
display.
●Adr = address of this unit on the databus
●Tag = vanity tag
●Nme = device name
●Loc = location of the device
Page 18 of 58
V262_User manual
Schleifenbauer PDU
How to view PDU connection information?
How can I check in which mode and with what protocol the PDU is running?
You will find all information related to the PDUs network connection in the IPv4
Link and IPv6 Link pages.
IPv4Link:
●Lnk = current Ethernet link status of the device
●St = IP status:
■DHCP: Acquiring/Bound, Static, Static fallback
■‘-‘ when there is no link
●IP = IP address of the device
●NM = subnet mask of the device
●GW = IP address of the Gateway or Router
●MAC = MAC address of the device
The IPv6 link will show up to 3 IPv6 addresses. The first one will be your link-local
address which will always start with FE80:: the second and third will be your LAN
and WAN address respectively.
In the “IP Interfaces” display you can find information about the device mode in
which the PDU is working:
●Mode = hybrid, databus , bridge, colocation, …
The display shows the status, and which protocol & port number is used for:
●HTTP
●API
●Modbus
●SNMP
●IPMode (IPv4, IPv6 or both)
See the chapter “Schleifenbauer databus: what is it?” in this manual
for explanations of the term hybrid, bridge, ….
When there is active communication with the PDU, the interface
colors will be inverted. Text is white and the background is blue.
When the interface is used, the text becomes blue and the
background white.
