 Do not touch high-voltage connections such as power supply terminals,

etc. to avoid electric shock.

 When the withstand voltage test or eac h test is perf ormed, please c ontact

RKC sales office or the agent. If you make a mistake in the test method,
the instrument failure may result.

 RKC is not responsible if this instrument is repaired, modified or

disassembled by other than factory-appr oved personnel. Malfunction can
occur and warranty is void under these conditions.

High temperature caution:
Do not touch the heat radiation fin wh ile the po wer is turne d on or just
after the power is turned off as it may be at high temperatures.
If touched, burning may result.

 This product is intended for use with industrial machines, test and measuring equipment. It is not

designed for use with medica l equipm ent and nuc lear ener gy.

 This is an Environment A instrument. In a domestic environment, this instrument may cause radio

interference, in which case the user may be required to take additional measures.

 Be sure to provide an appropriate surge control circuit respectively for the following:

 If input/output o r signal lines wit hin the bu ilding are long er than 30 meters.
 If input/output o r signal lines leav e the bui lding, r egardle ss the le ngth.

 This product is man ufactured on the assumption that it is mounted within a control panel. All

high-voltage connections suc h as power su pply term inals must be enclosed in t he control p anel
to avoid electric shock by operating personnel.

 All precautions described in this manual sho uld be taken to a void damage to th e instrument or

equipment.

 All wiring must be in accordance with local codes and regulations.
 Always use this product at the rated power supply voltage, load current and power frequency.
 All wiring must be completed before power is turned on to prevent electric shock, instrument

failure, or incorrect action.

 To prevent instru ment dam age or f ailure, p rotect t he power line and the inp ut/outp ut lines with a

protection device such as fuse, etc.

 If this product is used for ph ase control, higher harmo nic noise may be generat ed. Therefor e in

this case, take such measures as separating the power line from the high-voltage line for load
drive.

 Prevent metal fragments or lead wire scr aps from falling inside ins trument case to avoid el ectric

shock, fire or malfuncti on.

 Tighten each termin al screw to t he specifie d torque fo und in the ma nual to a void electric s hock,

2. MOUNTING

 In order to prevent electric shock or instrument failure, always mount

or remove this instrument after power supplied to the entire system
is turned off.

 As the temperature of this instrument becomes high, mount the

instrument on a non-inflammable material (metal plate, etc.).

 As this instrument generates a large amount of heat, it is cooled by

circulating air by convection. Therefore, if mounted in any direction
other than specified, accident or failure may result.

 To carry the instrument, wait for the radiation fin to cool down. Grip

the instrument firmly with your fingers on the an ti-slip parts on both
sides of the instrument.

To prevent electric shock or instrument failure, do not turn on the
power until all wiring is completed. Make sure that the wiring is correct
before applying power to the instrument.

CAUTION

 Match the ph ase between t he supply voltage for the instrumen t and the suppl y voltage

for the load. Without proper matchi ng, the ins trume nt may not work prop erly.

 Caution for conducting control of primary side of a transformer

 When a protection function for control of primary side of a transformer is provided:

To conduct control of primary side of a transf or mer , ma ke su re prot ec tio n fu nct io n for cont rol
of primary side of a con trol is set. Appropriately adjust the soft -start time for in case of
secondary side breakdown depending on the operating condition.

 When a protection function for control of primary side of a transformer is not provided:

If the action of the device i s influenced by exc essive current (i nrush current, current due to
flux saturation of transformer), use a transformer 1.25 T (magnetic flux density) or less.
Make sure soft-start time is appropriately set.

For setting procedure of each function, refer to THV-10 Instruction Manual

(IMR02W03-E).

 If the secondary side of the transformer goes open due to a break in the heater, connect resistor

in parallel on the primary side of the transformer to all ow current flow larger than th e minimum
load current (0.5 A or more) .
(Adjust the resistance value considering the exciting current of the transformer.)

 In order to comply with the European EMC- and LV directive the no ise filter (shown in the

following figure) should be applied.

Therefore install the fuses and switches near the instrument, if necessary.

 To avoid noise induction, keep input signal wire of controller away from instrument power line,

load lines and power lines of other electric equipment. If wiring near high-voltage power is
unavoidable, use shielded wires.

 Use wires satisfying the rated current capacity.
 Tighten the hexagon headed bolts on the main circuit terminals using a torque wrench. Always

tighten each of them by contacting the diagonal surfaces of the wrench with those of each
hexagon head.

 Firmly tighten each terminal hexagon headed bolt with the tightening torque specified below.

Otherwise, electric shock, fire or heat generation may result.

 Choose solderless terminals from the following table.
