Through type zero-phase current transformer

Split type zero-phase current transformer Model ZT15B/ZT30B/ZT40B/ZT60B/ZT80B/ZT100B Model CZ-22S/ CZ-30S/ CZ-55S/ CZ-77S/ CZ-112S

Users Manual This instruction manual is for zero-phase current transformer(not included) and split type zero-phase current transformer(not included) that use with measuring unit. Be sure to read this instruction manual and the manual of measuring unit before use. The following items for zero-phase current transformer(not included) are included in package. Check that no items are missing Through type zero-phase current transformer(ZT15B/ZT30B/ZT40B/ZT60B/ZT80B/ZT100B)1

or split type zero-phase current transformer(CZ-22S/ CZ-30S/ CZ-55S/ CZ-77S/ CZ-112S)1 Instruction manual1(CZ-22S/ CZ-30S/ CZ-55S/ CZ-77S/ CZ-112S)

1Safety Precautions 1.1 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(-5C to +55C).

Places exposed to direct sunlight. Places where the out of the cabinet.

Places where the humidity exceeds the humidity range (30% to 85%RH) or where condensation occurs.

Places where metal pieces or inductive substances are laying around.

Places with strong electromagnetic field or noise.

Places with a lot of dust, corrosive gas, salt or oily smoke. Places with a lot of vibration or impacts. Places where the unit may be exposed to rain or drops of water.

Place where the altitude exceeds 2000m. Places where the circuit with many harmonics.

Places where the daily average temperature exceeds 35C.

1.2 Precautions concerning preparations before using the equipment Use the unit in the specified usage environment and conditions.

Check the current and voltage ratings of the equipment.

Dont give this product vibration, a shock at the time of the transportation as much as possible.

1.3 Precautions concerning installation and connection

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.

Before installing and connecting the unit, read the instruction manual without fail. For safety, the unit shall be installed and connected by experts in electrical work. Connect the wires carefully, checking the wiring diagram. Incorrect wiring can cause unit failures, fires, and electric shocks. ULc-UL listed corresponds, use the wires according to the following conditions and UL-listed crimp type terminals.

Single wireAWG24AWG18(0.51.0mm), Stranded wireAWG20AWG16(0.81.3mm2) 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 Zero phase current transformer is high-precision magnetic material. Please use not to applied weight of primary through type electric wire and external force. Please hold not to applied weight of primary through type electric wire to zero phase current transformer. It might be cause of exterior destruction. Use the crimp-type terminal for secondary terminal and test terminal. If inappropriate crimp-type terminal is used, a wire breakage or a contact failure may occur, which may cause a device malfunction, a failure, a burnout or a fire. Please wire not give vibration and impact directly in secondary terminal. Read the manual of measuring units which is used with zero-phase current transformer, and is used well, and follow it. Use this zero-phase current transformer in cabinet certainly. Confirm that a terminal is closed surely. The lack of clamping causes malfunction of the machinery, a fire, the electric shock. Carry out the clamping of the crimp-type terminal lugs by prescribed torque. The excessive clamping becomes the ruination of a terminal and the screw. As for the panel, it be assumed that it was given the following matters.

a) It is necessary to attach a key to the cabinet. b) The structure that a power supply is intercepted automatically is necessary when opening a cabinet.

1.4 Precautions concerning in using

Use the unit 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. Do not open the secondary side of the ZCT while the primary current is running.

1.5 Precautions concerning maintenance and inspection Wipe off the surface dirt with tender cloth. Dont let chemical cloths touch it for a long time, and do not wipe it with benzine or thinner. Use a soft dry cloth to clean off dirt of the unit division surface. Check for the following items to use this unit properly for long time.

1Daily inspection Does not this product have the damage? Are not there an abnormal sound, bad-smelling fever?

2Periodic inspectionCheck once in 6 months to 1 year Are not there installation, the slack of the screw?

1.6 Precautions concerning storage When storing the unit, turn off power, disconnect cables and wires, and put them in vinyl bags or the like. When storing the unit for a long time, avoid keeping it in the places shown below.

Places where the ambient temperature is out of the range from -10C to +60C.

Places with a lot of vibration or impact.

Places where the humidity exceeds the humidity range (5% to 95%RH) . Places where the unit is exposed directly to rain, water droplets. Places with a lot of dust, corrosive gas, salt or oily smoke. Places where metallic particles or inductive substances are laying

around.
