3.About the Product
This product is a module to monitor leakage current of the equipment in a live state that is driven by
three-phase alternating current power. Set this module to operate along with the CONPROSYS series
configurable type CPU module controller.
It has a function useful for early deterioration discovery in the three-phase motor or invertors, which
are widely used in the FA factories or water treatment facilities, for instance in a pump, and the system
can be examined while power is active.

4.Features
1. Hardware features
Find isolation deterioration in motor
This product finds isolation deterioration of the three-phase induction motor by calculating isolation resistance from the measured
applied voltage as well as ground fault current to the three-phase induction motor (three-phase motor).
With the Modes-IOTM measurement method, isolation resistance in a live state can be accurately measured, and it is applicable to detect
isolation deterioration of the three-phase induction motor.
The product can be set either in front of or behind the inverter.
* The measurement method of TANASHIN DENKI CO.,LTD. is applied for this product.
No base board required
As the product requires no base board for installation, it helps add modules easily and smoothly.
Installed modules can be removed from any set positions on DIN rail.
Compact design
Compact design, 25.2(W)×94.7(D)×124.8 (H), features flexibility in installation.
Adaptable to a temperature range between -20 and
+60°C
The product is capable of operating in the temperature between -20 and + 60°C. It can be installed in the various environments.
Equipped with LED for an operation check
The product has LED for an operation check, which helps you visually confirm the communication status of each interface.

2.Handling Precautions
DANGER
Do not use the product in locations exposed to a flammable or corrosive gas. It may cause
explosion, fire, electrical shock, or malfunction.
Do not allow the device to come into contact with foreign substances (metal particles,
flammable substances, liquids, etc.) Otherwise, it can cause fire or electrical shock.
Do not place the product in an unstable location or use incomplete mountings. Otherwise, it
may cause the device to fall.
Be sure to connect the product to the stipulated power supply voltage. Connecting to a
different voltage might cause a fire or electrical shock.
If the product is used in a manner not specified by the manufacturer, the protection provided
by the equipment may be impaired.
The product is not intended for use in aerospace, space, nuclear power, medical equipment,
or other applications that require a very high level of reliability. Do not use the product in
such applications.
If using the product in applications where safety is critical such as in railways, automotive, or
disaster prevention or security systems, please contact your retailer.
Do not touch the product or ZCT unit with your hands when the product is in operation.
It can cause electric shock.
Double check that voltage in the distribution system is inactive before connecting a cable
through the ZCT unit or to the voltage measurement connector. Touching electrodes can
cause electrical shock.
Use a covered cable that is isolated by greater voltage than used voltage to connect through
the ZCT unit or to connect with the voltage measurement connector. Insufficient isolation can
cause electrical shock.

CAUTION
Be certain the following requirements are satisfied when using the product.
- Indoor use
- Altitude up to 2000m
- Applicable POLLUTION DEGREE 2
- The place to be measured should not exceed 300VAC (CAT III), or 600VAC (CAT II).
When using the product at high altitudes, refer to the relational expression below to find an
appropriate ambient temperature. The heat dissipation decreases due to air pressure drop
and could lead to damages or a shorter product life.
- Ambient temperature = 60[°C] - 0.005 x altitude [m]
An Example)
The product is used at 2000 meters
60°C - (0.005 x 2000m) = 50°C (Ambient temperature)
Do not use or store the product in a location exposed to extremely high or low temperature
that exceeds range of specification or susceptible to rapid temperature changes.
e.g. - Exposure to direct sun
- In the vicinity of a heat source
Do not use the product in extremely humid or dusty locations. It is extremely dangerous to
use the product with its interior penetrated by water or any other fluid or conductive dust. If
the product must be used in such an environment, install it on a dust-proof control panel, for
example.
Avoid using or storing the product in locations subject to shock or vibration that exceeds
range of specification.
When transporting the product, take suitable measures to avoid applying shock or vibration
directly to the product.
Impact resistance: 15G (11ms) below.
Use the product in the specified operating condition (temperature, humidity, vibration and
shock).
Avoid installing in the place where ventilation of the product may compromise. Insufficient
aeration could heat up the product and lead to malfunctions or damages.
Do not use the product in the vicinity of devices that generate strong magnetic force or noise.
Such products will cause the product to malfunction (stop, reboot).
Do not use or store the product in the presence of chemicals.
When removing connectors or cables, always unplug the power cables and confirm the LEDs
are turned off.
Do not modify the product. CONTEC will bear no responsibility for any problems, etc.,
resulting from modifying the product.
In the event of failure or abnormality (foul smells or excessive heat generation), unplug the
power cables immediately and contact your retailer.
To connect with peripherals, use a grounded, shielded cable.

To clean the product, wipe it gently with a soft cloth dampened with either water or mild
detergent. Do not use chemicals or a volatile solvent, such as benzene or thinner, to prevent
the paint to be scraped or discolored.
When connecting cables, first check the shapes of connectors, and then insert them in the
correct orientation. After they are connected, do not put too much load on the connected
part. Doing so may result in poor contact or damage to the product and the connected part.
Do not touch metal parts or terminals with your hands when the product is in operation.
Otherwise, the product may malfunction, or cause failure.
Do not touch the product or connectors with a wet hand to avoid electric shock.
The specifications of the product are subject to change without notice for enhancement and
quality improvement. Even when using the product continuously, be sure to read the manual
in the CONTEC’s website and understand the contents.
When the product is used in a place that is affected by overcurrent or overvoltage (lightning
surge), select appropriate surge protection device for all of the route (Signal line, etc.).
Consult with the specialist regarding selecting, purchasing, and setting the surge protection
device.
When disposing of the product, follow the disposal procedures stipulated under the relevant
laws and municipal ordinances.
Always attach the end cover while power is active.
The product is an open-type device (a device designed to be housed inside other equipment)
and must always be mounted inside a mechanical enclosure having enough strength.
To avoid induced noise, wiring to the product should be separated from the power line with
high voltage or large current. Also, avoid parallel wiring or use the same wiring with the power
line.
Accurate measured value may not be obtained if the cycle of the motor rotation is matched to
the commercial frequency or close to the higher harmonic having three times of commercial
frequency.
The product cannot measure with open-delta connection for three-phase single-phase system
or ungrounded circuit type
For penetrating circuit, use penetrable circuit voltage, choose an isolated cable with proper
material and diameter for the rated current, or do not use a non-isolated cable or a conductor
(bus bar).
The ZCT unit should be set 10 cm farther away from large current of 1000A or larger to avoid
the influence of external magnetic.
Secure the ZCT UNIT firmly to prevent the weight of the penetrating circuit or external force
from applying.
If the ZCT unit is set in the vicinity of devices that generate strong magnetic force such as a fan
motor, a transformer, or an electromagnetic switch, it may affect the measurement accuracy.
When removing the cables of the ZCT unit from the module, do not pull them as it results in
the breaking of cables.
The ZCT unit cables should not be bent repeatedly and should minimize material stress.
