•If a Residual Current Circuit Breaker (RCCB or
ELCB) is required, type B with a 300 mA tripping
current must be used (the RCCB should only
supply one VSD). An unfiltered VSD should be
used or if the VSD has an EMC filter this must be
disconnected, due to the filter leaking current to
earth. The neutral conductor in the system must
be grounded
•Wait at least 5 minutes after the power has been
turned off, before opening the equipment. The
DC link capacitor remains charged to dangerous
voltages even when the power is removed. When
working on open equipment, note that live parts
are exposed, do not touch such parts
•Do not connect machines with a 3-phase power
supply, fitted with EMC filters, to a supply via an
ELCB (Earth Leakage Circuit Breaker - see EN 50
178, section 6.5)
•Note that certain parameter settings may cause
the VSD to restart automatically after an input
power failure
•Do not use this equipment as an “emergency
stop” mechanism (see EN 60 204, 9.2.5.4)
•Note that certain parameter settings may cause
the VSD to start automatically
•Obey all general and regional installation and
safety regulations relating to work on high-voltage
installations, as well as regulations covering

motor overload protection in accordance with
UL508C, section 42. An external PTC can also
provide motor overload protection via a special
input
•This equipment is suitable for use in a circuit
capable of delivering not more than 10'000
symmetrical amps (rms) for a maximum voltage of
AC 230 / 460 V when protected by a time delay
fuse
•Do not use the unit with a motor of a higher
nominal power rating than the VSD, or a nominal
power less than half that of the VSD. Only operate
the VSD when the nominal current in P0305
exactly matches the motor rating plate nominal
current
•When using the analog inputs, the DIP switches
must be correctly set and the analog inputs
correctly configured before enabling them. If this
is not done, the motor may start inadvertently
Caution
•Do not allow children or the general public to
access or approach this equipment

1.1 Operation in the event of fire or emergency situations (ESM)
The user of the SED2 variable speed drive must be aware that fire / emergency operation may only be activated
should crucial events occur (e.g. fire), where continued operation of the motor (fan) is mandatory to ensure smoke
and heat extraction, for instance, in order to facilitate the evacuation of people.
When triggering fire / emergency operation, certain alarm and fault status messages of the SED2 (e.g.
overtemperature of SED2, breakdown of bus communication) will be suppressed. In the case of other faults (e.g.
overvoltage or overcurrent), restarts will permanently be triggered. Suppression of the protective functions shall
ensure that – during fire / emergency operation – the motor continues to run as long as possible.
When using this operating mode, damage to the SED2 itself cannot be excluded, be it due to failure of internal
components or fire caused by excessive heat. In addition, it must be taken into account that – due to the
parameterized behavior of the SED2 – other HVAC plant components can also be damaged during fire /
emergency operation. This includes air dampers, for example, which can be damaged as a result of overpressure
(e.g. when the maximum motor speed is parameterized). Such damage can lead to HVAC plant malfunction or
failure – a fact to be considered when triggering fire / emergency operation.
For these reasons, Siemens Building Technologies assumes no responsibility for any faults, malfunctions and
damage of the SED2 itself or of any other types of components used in the relevant HVAC plant, or for direct or
indirect damage resulting from activation of fire / emergency operation.
The correct functioning of fire / emergency operation depends on the right selection of the HVAC system
components of which the SED2 constitutes only one component. Plant used in vital sectors, such as ventilation
plant that need to mandatorily and constantly deliver a certain amount of outside air, must be approved by the
respective authorities.
Fire / emergency operation can be triggered via one of the 6 digital inputs DI1...6. The display shows alternately
“ES“ and the motor’s frequency.
Fire / emergency operation can be deactivated any time via the digital input that was used for activation. Then, the
SED2 will resume normal operation as parameterized.

Building Technologies 2 Introduction 29.07.2010
2 Introduction
2.1 General
These are the Operating Instructions for the SED2 and are to be used for quick and simple commissioning.
The SED2 range comprises VSDs for controlling the speed of fans and pump motors. The SED2 can also be
programmed to manage many other motor functions and limits. These functions are set by parameters, which are
programmed with the help of the operator panel.
2.1.1 Types of system control
The SED2 range of VSDs are normally controlled using the operator panel or input / output terminals. Optionally,
the SED2 can also be controlled via the integrated RS-485 port.
The output frequency or motor speed can be changed via the analog inputs, the digital inputs or the operator panel.
•In “Hand” mode, buttons on the operator panel can be used to change the motor speed
•A number of fixed frequencies can be set by appropriate parameterization of the digital inputs
•The motor speed can be changed via the analog inputs by means of a voltage or current value in accordance
with the DIP switch settings

Building Technologies 4 EMC-compatible installation of SED2 29.07.2010
4 EMC-compatible installation of SED2
4.1 Why EMC-compatible installation?
If no measures against electromagnetic interference are taken, VSDs will cause interference. These interference
signals can produce the following problems near the VSD:
– Distortion of analog signals, for example from BMS, leading to a distortion of measured values
– Sporadically occurring errors
– Unstable control
– Malfunction of other devices located near the VSD
– Malfunctioning of communication equipment
This means that reliable operation of VSDs and associated equipment can be ensured only if the following
interference suppression measures in compliance with EMC are taken:
•When installed in accordance with the wiring SED2 recommendations of this Manual. The units comply with the
European Norm EN 61800-3, “Adjustable speed electrical power drive systems”. This standard specifies
different limits for domestic and industrial applications, which define whether an integral EMC filter is required
•When units are selected which include integral filters, they will meet the conducted and radiated RFI emission
limits specified in EN 55011
4.2 Mounting IP20 versions of the VSD in a control cabinet
•Group power electronics devices, such as mains fuses, motor protection switches, contactors, starters, or VSDs
in the control cabinet and segregate them from sensitive controls and measuring equipment and their lines by
galvanically conductive, grounded partitions
•Locate the VSD(s) in the control cabinet such that the mains, motor and potential equalization cables can be
run directly and be kept as short as possible
•Ensure that there is proper galvanic bonding between the metal rear of the VSD and the mounting rail or grid
via the fixing screws. Mounting rail or grid must be electrically conductive and must not be painted
•Remove insulating layers of grease, paint, or other protective layers where ground and protective earth
connections are to be made, or use adequate connecting elements
•Protect contact or connection points against corrosion. Inner walls should be galvanized
•If an external EMC input filter is required, install it as close as possible to the VSD and ensure that its metal
housing is adequately grounded via the mounting rails or the mounting grid. With frame sizes A …C, use the
relevant EMC filters for mounting underneath the VSD. For connection of the EMC filter to the inputs of the
VSD, use shielded cable and connect the shielding to ground by means of grounding clamps
•Check to ensure that contactors and relays in the control cabinet, if present, are suppressed against radio
noise, either with RC units in the case of AC contactors, or with freewheeling diodes in the case of DC
contactors, whereby the suppression devices are to be connected to the coils
4.3 Mounting IP54 versions of the VSD
•Install the VSD as close as possible to the motor to be driven (monoblock, fan or pumps)
•Remove insulating layers of grease, paint, or other protective layers where ground and protective earth
connections are to be made
•Protect contact or connection points against corrosion
Important note: When mounting IP54 versions of VSDs to concrete or brick walls or other nonconductive
surfaces, it is mandatory to connect the VSD metal housing via a large potential equalization
line of low impedance to ground (potential equalization rail). For that purpose, we recommend to
use a ribbon type, tin-plated copper mesh or similar with a cross-sectional area of at least
16 mm2.

13 / 100
Siemens Commissioning Guide CM1G5192en
Building Technologies 4 EMC-compatible installation of SED2 29.07.2010
4.4 EMC-compatible wiring
•Use only shielded cables for the motor. The shielding should have the lowest possible HF impedance and must
be continuous
•Use only shielded cables for the signal, control and data lines (shielded twisted pair)
•The HF transfer resistance at the connecting points between shielding and housing should be kept as low as
possible
•Connect the shielding of motor and control cables to ground at both ends. For that purpose, use EMC cable
fittings (EMC fittings, EMC cable clamps, EMC terminals and similar that ensure 360° contact of shielding)
•Avoid high equalization currents on the shielding by ensuring a low-resistance (min. 16 mm2 copper) and low-
impedance connection between VSD housing and ground (potential equalization rail)
•Connect the neutral conductor of the motor controlled by the VSD directly to the earth connection (PE) of the
associated VSD
•Avoid cable loops
•Supply power to all devices in a starlike pattern
4.4.1 Potential equalization and earthing
•Connect all electrical components separately (starlike) to potential equalization
•VSDs using filters produce discharge currents which, in the event of fault (e.g. mains failure), can significantly
exceed rated currents. To avoid dangerous voltages, all VSDs of protection class IP54 or IP20 must therefore
be earthed via the metal frame or the earth terminal . In the case of discharge currents exceeding 3.5 mA,
one of the 3 following criteria must be satisfied to ensure compliance with EN 50178 and EN 60335: Either
−the potential equalization line must have a cross-sectional area of at least 10 mm2, or
−the potential equalization line must be monitored for disruptions, or
−a second potential equalization line must be installed
Since discharge currents represent high-frequency disturbance variables, earthing must always be of low
resistance using large surfaces and the shortest path from the VSD to earthing or the potential equalization
line.
•For potential equalization lines, use flat, ribbon type conductors,
tin-plated copper mesh or similar (cross-sectional area at least
16 mm2) as they have a lower impedance at high frequencies
•Connect each motor controlled by the VSD to the ground or earthing point of the monoblock, also using a
potential equalization line having a large cross-sectional area (refer to illustrations on pages 15 and 16)
•Ensure that each piece of control equipment (e.g. a PLC or a BACS1) connected to the VSD is connected to the
same ground or same earthing point as the VSD using a short potential equalization line (potential equalization
rail)

Siemens Commissioning Guide CM1G5192en
Building Technologies 4 EMC-compatible installation of SED2 29.07.2010
•Connect movable parts (e.g. control cabinet doors or
hinged frames) via flexible grounding mesh
•Connect grounding to earth via protective conductors since, even in the event of fault, grounding must not carry
hazardous voltage
•Avoid earth loops
4.4.2 Routing the cables
•Lay cables of different power sections, such as control, mains and motor cables, separately
•Avoid undesired coupling caused by parallel running control, power and motor cables
•Lay control, mains and motor cables separately, in separate cable ducts at a distance of at least 200 mm (see
illustration below). If cables must be crossed, run them at an angle of 90° if possible
90°
> 40 cm > 20 cm
> 20 cm
5192Z37en
Motor cable
Mains cable
Signal cable
Signal / control cable
•Keep cables to motors as short as possible, generally not exceeding 25 m
•If possible, lay external cables in sheet metal ducts or on metal carriers. The metal cable duct or carrier should
be earthed and its individual parts should be galvanically connected
•If it is not possible to run control, power and motor
cables separately in separate cable ducts or cable
carriers, the cable duct or carrier must at least have
metallic galvanically conductive partitions

4.4.3 Cable shielding connections
•The quality of the shielding connection to ground is decisive for the effectiveness of shielding. All shielding
connections must be “HF-tight“, that is, coaxial, low-resistance and low-inductance
•Shielding should be run as close as possible to the device or the respective subassembly
•For IP54 versions of the VSD of frame sizes D…F, use metal
cable fittings as depicted here for the connection of shielded
cables (refer to Mounting Instructions for EMC cable fittings)
Shielding
•For IP20 versions of the VSD of frame sizes A.…C, we recommend to use the optional gland plates to improve
the connection of cable shielding to ground of the VSD
•Avoid pigtails when connecting shielding. Use EMC earthing clamps, cable clamps or shielding connection
clamps that ensure 360° contact (see illustration below)
