1.7 Disposal
Abide by the national regulations and laws governing the disposal of this de-
vice. Ask your supplier if you are not sure how to dispose of the old equip-
ment.
The directive on waste electrical and electronic equipment (WEEE directive)
and the directive on the restriction of certain hazardous substances in electri-
cal and electronic equipment (RoHS directive) apply in the European Commu-
nity. In Germany, these policies are implemented through the "Electrical and
Electronic Equipment Act" (ElektroG). According to this, the following applies:
 Electrical and electronic equipment are not part of household waste.
 Batteries and accumulators are not part of household waste and must
be disposed of in accordance with the regulations.
 Old electrical and electronic equipment from users other than private
households which was introduced to the market after 13th August
2005 must be taken back by the manufacturer and disposed of prop-
erly.
For more information on the disposal of Bender devices, refer to our home-
page at www.bender.de > Service & support.

2.3 Intended use
Load current monitor with three measuring channels for monitoring three-
phase isolating transformers with currents up to 32/63 A.
According to the standards set down for power supplies in medical locations
(DIN VDE 0100-710 (VDE 0100-710), ÖVE/ÖNORM E 8007, IEC 60364-7-710), it
overload protection of isolating transformers by disconnection is not allowed.
Instead, monitoring of overload and high temperature is required for the
medical IT transformer In combination with the isoMED427P or the 107TD47,
the CMS460-D4 has the task of monitoring the load current for three-phase
transformers.
In order to meet the requirements of the applicable standards, customised pa-
rameter settings must be made on the equipment in order to adapt it to local
equipment and operating conditions. Please heed the limits of the range of
application indicated in the technical data.
Any use other than that described in this manual is regarded as improper.

3. System description
In buildings and industrial installations, a fault or failure of the power supply
involves high costs. In installations which require high fault tolerance and
good safety, three-phase isolating transformers should be monitored contin-
uously for overload.
3.1 Features
 Three true r.m.s. measuring channels for measuring the three load cur-
rents of three-phase isolating transformers
 Determination of the maximum load current of the three measured
values
 Selectable measuring current transformer types: STW2/STW3/STW4
 Adjustable response value
STW2 , STW3: 1…32 A
STW4 1…63 A
 Measuring range
STW2 , STW3: 1…55 A
STW4 1…110 A
 Alarm on channel 4 when 100 % of the response value are reached or
exceeded on at least one of the channels 1…3
 Adjustable time delay ton
 History memory with date and time stamp for 300 data records
 Data logger 300 data records per channel
 Analysis up to the 40th harmonic (THF)
 Two alarm relays with changeover contact; N/O or N/C operation
selectable
 Connection possibility for external test and reset buttons
 Backlit graphic display and alarm LEDs

System description
16 CMS460-D4_D00166_01_M_XXEN/02.2021
 Data exchange via BMS bus
 Parameterisation with password protection
 RoHS-compliant
3.2 Description of function
The currents are detected and evaluated as true r.m.s. values in the frequency
range of 42…2000 Hz. All channels are scanned simultaneously so that the
maximum scanning time for the three channels is ≤ 180 ms if 1x the response
value is exceeded and ≤ 30 ms if 5x the response value is exceeded.
The CMS460-D4 determines the maximum current of the three measuring
channels and outputs these as a load value, which is represented as percent-
age of the response value.
The currents of the three measuring channels are shown on the display in bar
graph format and are available via the BMS bus on the channels 1…3.
The maximum load value currently measured is available via the BMS bus on
channel 4.
If the maximum response value of the load current is reached or exceeded the
relays will be activated and an alarm is signalled via the BMS bus on channel 4
as soon as the response delay ton has elapsed.
Both alarm LEDs on the device light up.
In addition to the load current measurement, the CMS460-D4 analyses the
harmonics of the measuring channels 1…3 up to the 40th harmonic and indi-
cates it as a THF value (THF=Total Harmonic Factor).
CT connection faults are indicated via LED (Alarm 1) and can be queried via
the BMS bus (channels 1…3).

3.3 Connecting measuring current transformers
Fig. 3.1: STW2…4
The CMS460-D4 can only be operated with STW2, STW3 and STW4 measuring
current transformers. For details refer to ordering information.
History memory
The device utilises a history memory for failsafe storing of up to 300 data
records (date, time, channel, event code, measured value), so that all data
about an outgoing circuit or an area can be traced back at any time (what hap-
pened when).
Analysis of harmonics
The channel displaying the harmonics of the measured currents can be select-
ed via the menu item ("Menu" - "4. Harmonic"). There, both the THF and the
current value of the harmonics (1…40 at 50/60 Hz) is displayed numerically
and graphically. In addition, the DC component is displayed.

System description
18 CMS460-D4_D00166_01_M_XXEN/02.2021
The THF describes the harmonics the r.m.s value of an alternating quantity in
proportion to the fundamental r.m.s. value. The smaller the THD factor, the
more sinusoidal the current signal.
The THF is determined and indicated for the channels 1…3.

4. Installation and connection
4.1 Unpacking
 Unpack all the parts supplied with the system. Avoid sharp-edged tools
that may damage the content of the packaging.
 C ompare your order with our delivery note to check that you have received
all products in full. The article numbers and type designation printed on
the nameplates provides an easy means of uniquely identifying each
device.
 Check all parts supplied for any evidence of damage in transit. Do not
use devices damaged in transit. If a device has sustained damage,
please contact Bender. Details of who to contact are indicated on the
delivery documents.
 When storing the devices in a cold environment as it is in winter the fol-
lowing is to be considered: Leave the devices to stand for 3 to 4 hours
at room temperature before connecting the power supply. When the
devices are moved from a cold to a warm environment, condensation
will be evident on all parts. Putting damp devices into operation risks
damaging electrical components and there is a danger of electric shock
on contact.
4.2 Fuses, max. voltage, cable lengths
 Equip the supply voltage of all system components with fuses.
IEC 60364-4-43 requires protective devices for short-circuit protection.
We recommend the use of 6 A fuses.
 When using busbar systems, please note: The maximum voltage of the
monitored system must not exceed the nominal insulation voltage of the
measuring current transformers used in the CMS460-D4.

Installation and connection
20 CMS460-D4_D00166_01_M_XXEN/02.2021
 Select the cables and cable lengths according to the technical data on
page 62. If you use cables that are longer than those specified here,
Bender cannot guarantee that the equipment will function safely.
 For UL-application:
– Use at least 60/70 °C copper lines!
4.3 Notes on mounting
The devices are suitable for the following installation methods:
 Standard distribution panels according to DIN 43871
 DIN rail mounting according to IEC 60715
 Screw mounting using M4 screws
Danger of electric shock!
Before fitting the device and prior to working on the device
connections, make sure that the power supply has been
disconnected and the system is dead.
The electrical installation may sustain damage and the
device be destroyed beyond repair.
Risk of electric shock due to open current transformer
connections!
When operating incorrectly connected measuring
current transformers there is the risk of an electric shock
and/or flashovers.
Avoid open transformer connections and ensure that the
electrical installation is de-energised!
