1. Safety Precautions
1.1 Precautions concerning working environment and conditions
Do not use the unit in any of the following places. Doing so may cause malfunctions or a reduction in service life.
+ Places where the ambient temperature exceeds the working temperature range (-20°C to +50°C) * Places where the unit may be exposed to rain or drops of water, and direct sunlight
(Places where the daily average temperature exceeds +35°C) * Places where the circuit with many harmonics.
* Places where the relative humidity is 85%RH or more or where condensation occurs « Places with strong electromagnetic field or noise
* Places with a lot of dust, corrosive gas, salt or oily smoke * Places where the out of the cabinet.
* Places with а lot of vibration or impacts * Place where the altitude exceeds 2000m
1.2 Precautions concerning preparations before using the equipment
° Use the unit in the specified usage environment and conditions.
* Check the current ratings of the equipment.
1.3 Precautions concerning installation and connection
For safety, the unit must be installed and connected by experts in electrical work.
e Don't give this product vibration, a shock at the time of the transportation as much as possible.
A Danger | : Perform installation, disassembly, the wiring work after intercepting a power supply by all means. There might be the damage of an electric shock or the product.
<Precautions concerning installation and connection>
* Carry out the clamping of the crimp-type terminal lugs by prescribed torque (refer to figure 1). The excessive clamping becomes the ruination of a terminal and the screw.
* After tightening, be sure to check that all screws have been tightened. Failure to tighten any screw can cause unit malfunctions, fires, and electric shocks.
° Connect the wires carefully, checking the wiring diagram. Incorrect wiring can cause unit failures, fires, and electric shocks.
* Use an electric wire of the size of penetrating this ZERO PHASE CURRENT TRANSFORMER (ZCT) for primary side cable, do not use a non-insulation electric wire or a
metal for a primary cable
* Lay the connection of the second terminal so that vibration / a shock does not depend on the terminal part directly.
* Use an electric wire of the size of penetrating this ZCT for a primary side cable, do not use a non-insulation electric wire or a metal for a primary cable
A Caution * Use the M4 screws crimp type terminals appropriate for for which is suitable for electric wire size (1.2to 2.0mnt ). The use of the infelicity causes malfunction of the
machinery, trouble, a damage by a fire, the fire by outbreak of the poor disconnection and contact.
* To avoid the influence of external magnetic fields, the installation shall be at least 45cm away from large current bus bars with serveral 1000A.
* Read the manual of measuring units which is used with this ZCT , and is used well, and follow it
* Use this ZCT in cabinet certainly.
* Arrange an electric wire so that the weight of the electric wire does not depend on ZCT.
<To avoid getting shock>
* As for the panel, it be assumed that it was given the following matters
* It is necessary to attach a key to the cabinet.
° The structure that a power supply is intercepted automatically is necessary when opening a cabinet.
* Degrees of protection (IP code) needs to higher than IP2X level.
<Precautions concerning usage>
e Dust or rust on the split part can degrade the performance of the ZCT. Wipe the dirt from the surface with soft dry cloth.
. * Use this ZCT within the rated range stated here. Using the unit out of the rated range may cause not only malfunctions or unit failure, but also fires or burnout.
A Caution * Do not open the secondary side of the ZCT while the primary current is running. When the secondary side of the ZCT is open, the primary current runs while the secondary
current does not, which induces high voltage on the secondary side and increases the temperature. This may cause an insulation breakdown of the secondary winding and
results in burnout.
1.4 Precautions concerning maintenance
* Protect the unit from a power failure. Failure to do so can cause unit failures, fires, or electric shocks.
IN Caution * Wipe off the surface dirt with tender cloth. Don't let chemical cloths touch it for a long time, and do not wipe it with benzine or thinner.
+ Wipe off the separate surface on cores with tender cloth. Don’t use wet cloth.
1.5 Precautions concerning inspection
A Cauti « Perform the care for ZCT at the time of a periodic inspection with the blackout.
aution « When there is the loosen screws in a joint, fasten it again.
1.6 Precautions concerning storage
When storing the ZCT, disconnect cables and wires, and put them in vinyl bags or the like.
When storing the ZCT for a long time, avoid keeping it in the places shown below.
-Places where the ambient temperature is out of the range from -30°C to +60°C
(Places where the daily average temperature exceeds +35°C)
* Places where the relative humidity is 90%RH or more or where condensation occurs.
Places with a lot of dust, corrosive gas, salt or oily smoke.
1.7 Precautions concerning disposal
Dispose this product appropriately in accordance with the national or community rule. mounting bracket can be recycled as iron.
«Places with a lot of vibration or impacts.
«Places where the unit is exposed directly to rain, water droplets.
2.2 Installation points
1) Unscrew the short bar and take off the one side of the short bar.
2) Loosen a joining screw of ZCT in right and left side alternation equality and take off upper core.

2.4 Instructions for use
:ZCT is a highly precise magnetic material. Don't give a shock.
* Dust or rust on the split part can degrade the performance of the ZCT. Wipe the dirt from the surface with soft dry cloth.
"Ве sure to attach the short circuit plate. If you forget to install the short circuit plate, you will not be able to detect leaks correctly.
2.5 Instructions for wiring

«About the connection of the polarity (K, L) of ZCT, confirm it by the wiring diagram of the instruction manual of the measurement units put it together, and to use;
" Test terminals ( kt, It ) are terminals for movement test with the measurement units. It is convenience at the time of the maintenance check, if it draws wiring to the surface of the cabinet with a terminal
symbol.
-Do not be made to short-circuit at test terminals, the grounding is unnecessary, too. (ZCT cannot detect a leakage current definitely when it is grounding.)
