Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Quali󹪝ed Personnel
The product/system described in this documentation may be operated only by personnel quali󹪝ed for the speci󹪝c
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Quali󹪝ed personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

1.5 Cybersecurity information
Siemens provides products and solutions with industrial cybersecurity functions that support
the secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
cybersecurity concept. Siemens’ products and solutions constitute one element of such a
concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected
to an enterprise network or the internet if and to the extent such a connection is necessary
and only when appropriate security measures (e.g. 󹪝rewalls and/or network segmentation)
are in place.
For additional information on industrial cybersecurity measures that may be implemented,
please visit (https://www.siemens.com/industrialsecurity).
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customer's exposure
to cyber threats.

Description 2
2.1 Performance features
The PAC4220 is a Power Monitoring Device for measuring the basic electrical variables in low-
voltage power distribution. The device is capable of single-phase, two-phase or three-phase
measurement and can be used in 2, 3 or 4-wire TN, TT and IT systems.
The PAC4220 is designed for panel mounting. It is also possible to mount it on a DIN rail
using the DIN rail support brackets available as an option.
Thanks to its large measuring voltage range, the PAC4220 with a wide-voltage power supply
can be connected in any low-voltage system up to a rated line voltage of 690V (max. 600V
for UL). Higher voltages can be measured using voltage transformers.
Either x/1A or x/5A current transformers can be used for measuring current.
The large graphical color display is used to read o󹪜 all the measured values and to con󹪝gure
the device.
The integral Ethernet interface or the interface of an expansion module available as an
option can be used for communication, e.g. SENTRON PACRS485 expansion module or
SENTRON PACPROFIBUSDP expansion module or PAC SWITCHED ETHERNET PROFINET
module. The functions of the device can be expanded using other expansion modules
available as options. The PAC4220 has 2 interfaces which can accommodate up to 2 external
expansion modules simultaneously.
Measurement
• Measurement in 2, 3 and 4-wire systems Suitable for TN, TT and IT systems
• Measurement of all relevant electrical variables in a 50/60 Hz AC system
• Measurement of minimum and maximum values of all measured variables1)
• Calculation of genuine rms values for voltage and current to the 64thharmonic
• 4-quadrant measurement (import and export)
• Averaging of all measured values directly on the device in 2 stages, which are independent
of each other and freely con󹪝gurable (aggregation)1)
• Measurement of 1st to 63rdharmonics for voltage and current
• Calculation of the average voltage and current values over all phases
• Zero blind measurement
• High measuring accuracy: for instance, accuracy class 0.2 in accordance with IEC 61557-12
for active energy This means: an accuracy of 0.2% relative to the measured value under
reference conditions
• Measurement of N (neutral) conductor current2)
PAC4220
Equipment Manual, L1V30827278B-01 15

• Measurement of residual current and PE conductor current through external summation
current transformer 2)
• Measurement of physical variables (e.g. temperature, pressure, humidity) with external
0/4mA to 20mA transmitter1) 2)
1) This function will be available at a later time via a FW update.

ger%C3%A4tehandbuch-7km-pac-erweiterungsmodul-i(n)-i(di󹪜)-analog?dti=0&lc=de-DE)
Counters and power demand
• A total of 50 energy counters capture reactive energy, apparent energy, and active energy for
o󹪜-peak and on-peak, import and export on a phase-speci󹪝c basis.
• Energy consumption for active energy, reactive energy and apparent energy per day and
tari󹪜.
• Two con󹪝gurable universal counters1) for counting
– Limit violations
– Status changes at the digital input
– Status changes at the digital output
– Pulses of a connected pulse encoder (e.g. from electricity, gas, or water meters). The
pulse shape and time response must correspond to the signal shape described in the
IEC62053-31 standard.
• Operating hours counter1) for monitoring the operating time of a connected load. Counts
only in the case of energy counting above an adjustable threshold.
• One apparent energy counter, one active energy counter, and one reactive energy counter
for detecting the total energy import, regardless of the active tari󹪜 for display on the device.
• One apparent energy counter, one active energy counter, and one reactive energy counter
for detecting the power consumption of a manufacturing process. The process energy
counters can be started and stopped by means of the available digital inputs.
• Operating hours counter1) for recording the duration of a manufacturing process. The start
and stop commands of the digital input that controls the process energy counter start and
stop the operating hours counter. Up to 10counters can be used for detecting the
consumption of any media via digital inputs if the optionally available SENTRON PAC 4DI/2DO
expansion modules are used. Consumption (e.g. of gas, water, compressed air, electrical
current) can thus be recorded using simple media counters with a pulse output.
The display texts can be freely parameterized in a user-friendly way using
the SENTRONPowercon󹪝g (https://mall.industry.siemens.com/mall/en/WW/Catalog/Products/
10121795) con󹪝guration software.
