2. Safety instructions
DANGER
WARNING
CAUTION
Safety instructions
2.1 General safety instructions
Part of the device documentation in addition to this manual is the enclosed "Safety instructions for Bender products".
2.2 Work activities on electrical installations
Only qualified personnel are permitted to carry out the work necessary
to install, commission and run a device or system.
Risk of electrocution due to electric shock!
Touching live parts of the system carries the risk of:
• An electric shock
• Damage to the electrical installation
• Destruction of the device
Before installing and connecting the device, make sure that the installation has been de-energised. Observe the rules for working on elec-
trical installations.
If the device is used outside the Federal Republic of Germany, the applicable local standards and regulations must be complied with. The European standard EN 50110 can be
used as a guide.
2.3 Device-specific safety information
Make sure that the basic settings meet the requirements of the IT system.
Children and unauthorised persons must not have access to or contact
with the ISOMETER®.
Make sure that the operating voltage is correct!
Prior to insulation and voltage tests, the ISOMETER® must be disconnected
from the IT system for the duration of the test. In order to check the correct
connection of the device, a functional test has to be carried out before starting the system.
In the event of an alarm message of the ISOMETER®, the insulation fault
should be eliminated as quickly as possible.
If the ISOMETER® is installed inside a control cabinet, the insulation fault
message must be audible and/or visible to attract attention.
When using ISOMETER®s in IT systems, make sure that only one active
ISOMETER® is connected in each interconnected system. If IT systems are
interconnected via coupling switches, make sure that ISOMETER®s not
currently used are disconnected from the IT system and deactivated. IT
systems coupled via diodes or capacitances may also influence the insulation monitoring process so that a central control of the different
ISOMETER®s is required.
8
iso685-D-B_D00177_05_M_XXEN/07.2017
Prevent measurement errors!
When a monitored IT system contains galvanically coupled DC circuits, an
insulation fault can only be detected correctly if the rectifier valves (e.g.
rectifier diode, thyristors, IGBTs, frequency inverters, …) carry a minimum
current of > 10 mA.
Safety instructionsSafety instructions
2.4 Intended use
Only qualified personnel are permitted to carry out the work necessary
to install, commission and run a device or system.
Unspecified frequency range
When connecting to an IT system with frequency components below the
specified frequency range, the response times and response values may
differ from the indicated technical data. However, depending on the application and the selected measurement method, continuous insulation
monitoring is also possible in this frequency range.
There is no influence on the insulation monitoring for IT systems with frequency components above the specified frequency range, e.g. within the
range of typical switching frequencies of frequency inverters (2…20 kHz).
The ISOMETER® monitors the insulation resistance of unearthed AC/DC main circuits (IT
systems) with mains voltages of AC 0…690 V or DC 0…1000 V.
DC components existing in AC/DC systems do not influence the operating characteristics.
Due to the separate supply voltage, de-energised systems can also be monitored. The
maximum permissible system leakage capacitance is 0…1000 µF, depending on the profile.
Intended use also implies:
• The observation of all information in the operating manual
• Compliance with test intervals
In order to meet the requirements of applicable standards, customised parameter settings must be made on the equipment in order to adapt it to local equipment and operating conditions. Please heed the limits of the area of application indicated in the
technical specifications.
Any other use than that described in this manual is regarded as improper.

3.2.2 Special characteristics of ISOMETER® iso685-S-B with front panel
The ISOMETER® iso685-D-B and iso685W-D-B are devices of the iso685 device family with
integrated display. This manual applies in full to these ISOMETER®s.
The ISOMETER® iso685-S-B and iso685W-S-B are sensor variants of the iso685 device family without display. The only difference between these variants and the ISOMETER®s
iso685-D and iso685W-D-B is that they do not feature a display.
The ISOMETER®s iso685-S-B and iso685W-S-B must be used in combination with a front
panel because the devices are operated via the front panel. The operation of the front
panel is equal to the operation of the ISOMETER®s with integrated display, which is
described in this manual.
Only the sensor variant (ISOMETER® iso685-S-B or iso685W-S-B) can be
connected to the front panel. Connection to the display variant
(ISOMETER® iso685-D-B or iso685W-D-B) is not possible.
Hereafter, the ISOMETER®s with integrated display are described. This description is similar to the combination of ISOMETER® sensor variants and the front panel FP200. The devices to which this manual applies will be referred to as ISOMETER®s hereafter.
3.3 Functional description
The insulation monitoring device continuously monitors the entire insulation resistance
of an IT system during operation and triggers an alarm when the value falls below a preset response value. To obtain a measurement the device has to be connected between
the IT system (unearthed system) and the protective earth conductor (PE). A measuring
current in the µA range is superimposed onto the system which is recorded and evaluated by a micro-controlled measuring circuit. The measuring time is dependent on the
selected measurement profiles, the system leakage capacitance, the insulation resistance
and possible system-related disturbances.
3.2 Product description
3.2.1 General product description
The ISOMETER® is an insulation monitoring devices in accordance with IEC 61557-8 for IT
systems. The devices are universally applicable in AC, 3(N)AC, AC/DC and DC systems. AC
systems may include extensive DC-supplied loads (such as rectifiers, inverters, variablespeed drives).
10
The response values and other parameters are set using a commissioning wizard or via
different setup menus using the device buttons and a high-resolution graphical LC display. The selected settings are stored in a permanent fail-safe memory. Different
languages can be selected for the setup menus as well as the messages indicated on the
display. The device utilises a clock for storing fault messages and events in a history
memory with time and date stamp. The settings can be protected against unauthorised
modifications by entering a password. To ensure proper functioning of connection monitoring, the device requires the setting of the system type 3AC, AC or DC and the
red use of the appropriate terminals

The insulation monitoring device is able to measure the insulation resistance reliably and
precisely in all common IT systems (unearthed systems). Due to various applications, system types, operating conditions, application of variable-speed drives, high system leakage capacitances etc., the measurement technique must be able to meet varying
requirements in order to ensure an optimised response time and relative uncertainty.
Different measurement profiles which can be selected from a setup menu allow optimum
adaptation of the measurement technique to the specific application.
If the preset response value falls below the value of Alarm 1 and/or Alarm 2, the associated alarm relays switch, the LEDs Alarm 1 resp. Alarm 2 light and the measured value is
shown on the LC display (in case of insulation faults in DC systems, a trend graph for the
faulty conductor L+/L- is displayed). If the fault memory is activated, the fault message
will be stored. Pressing the reset button, resets the insulation fault message, provided
that the insulation resistance is at least 25 % above the preset response value. As
additional Information, the quality of the measuring signal and the time required to update the measured value are shown on the display. A poor signal quality (1-2 bars) may
be an indication that the wrong measurement profile has been selected.
The insulation monitoring device has an internal system isolating switch, which makes it
possible to operate several ISOMETER®s in coupled IT systems. For this purpose, the
ISOMETER®s are connected via an Ethernet bus. The integrated Isonet function ensures
that only one ISOMETER® is actively measuring at a time, while the other devices are completely isolated from the system and waiting in standby mode for measuring permission.
3.5 Self test
After switching on the supply voltage, the ISOMETER® automatically and continuously
checks all internal measuring functions, the components of the process control such as
the data and parameter memory, as well as the connections to the IT system and earth.
The self test can also be activated manually by means of the test button to check the functions of the relays (depending on the configuration) or it can be selected via the "Control"
menu (refer to “Control” on page 40).
The progress of the manual self test is shown on the LC display by a bar graph. Depending
on the conditions in the IT system being monitored, the self test is completed after
15…20 seconds. The device then returns to the standard mode (measurement mode)
and the actual measured value will be displayed after the measuring time has expired.
The display shows the message
ured (refer to “Initial measurement” on page 29).
If a fault is detected during the self test, the respective LEDs of the device light (refer to
“Alarm messages” on page 57). In addition, the respective message will be indicated on
the display and a previously programmed output will provide the respective signal.

Only qualified personnel are permitted to carry out the work necessary
to install, commission and run a device or system.
Risk of electrocution due to electric shock!
Touching live parts of the system carries the risk of:
• An electric shock
• Damage to the electrical installation
• Destruction of the device
Before installing and connecting the device, make sure that the installation has been de-energised. Observe the rules for working on elec-
trical installations.
Risk of electric shock!
Nominal voltages up to 1000 V may be present on the terminals L1/+ to
L3/- which can be lethal. Make sure the terminal covers are properly
mounted and clicked in before putting the device into operation.
17
Risk of electric shock!
High voltage is applied at the terminals, which in case of direct contact
can be life-threatening. If the terminals L1/+, L2, L3/- of the device are connected to a live IT system, the terminals E and KE must not be disconnected
from the protective conductor (PE).
Warning of insulation monitoring devices that do not work correctly!
Connect the terminals KE and E individually to the protective earth conductor PE.

Provide line protection!
According to DIN VDE 0100-430, a line protection shall be provided for the
supply voltage.
Risk of injury from sharp-edged terminals!
Risk of lacerations.
Touch the enclosure and the terminals with due care.
Ensure disconnection from the IT system!
When insulation or voltage tests are to be carried out, the device must be
isolated from the system for the test period. Otherwise the device may be
damaged.
Risk of property damage due to unprofessional installation!
If more than one insulation monitoring device is connected to a conductively connected system, the system can be damaged. If several devices
are connected, the device does not function and does not signal insulation faults. Make sure that only one insulation monitoring device is connected in each conductively connected system.
The ISOMETER® iso685-D-B is suitable for use in coupled systems. For the
necessary parameter setting, refer to “Special functions for coupled IT sys-
tems” from page 49
Prevent measurement errors!
When an AC system being monitored contains galvanically coupled DC
circuits, take into consideration that: an insulation fault can only be detected correctly when the rectifier valves carry a minimum current of
>10 mA.
For UL applications:
Use 60/70 °C copper lines only!
For UL and CSA applications, the supply voltage must be protected via 5 A
fuses.
18
Risk of property damage due to unprofessional installation!
The connecting lines L1/+, L2, L3/- to the system to be monitored must be
carried out as spur lines. Inadmissible load current can result in damage
to property and personal injury. Do not apply any load current to the terminals.
Check proper connection!
Prior to commissioning of the installation, check that the device has been
properly connected and check the device functions. Perform a functional
test using an earth fault via a suitable resistance.
