Safety Precautions

 Pictorial Symbols (safety symbols)

Various pictorial symbols are used in this manual to ensure safe use of the product, to
protect you and other people from harm, and to prevent damage to property. The symbols
are described below. Be sure you thoroughly understand the meaning of the symbols before
reading this manual.

: This mark indicates precautions that must

be taken if there is danger of electric shock,
fire, etc., which could result in loss of life or
injury.

This mark indicates that if these precautions

:

and operating procedures are not taken,
damage to the instrument may result.

: This mark indicates that all precautions

should be taken for safe usage.

 An external protection device must be installed if failure of this instrument

could result in damage to the instrument, equipment or injury to personnel.

 All wiring must be completed before power is turned on to prevent electric

shock, fire or damage to instrument and equipment.

 This instrument must be used in accordance with the specifications to

prevent fire or damage to instrument and equipment.

 This instrument is not intended for use in locations subject to flammable or

explosive gases.

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

to avoid electric shock.

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

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

IMR02L04-E3

i-1

 This product is intended for use with industrial machines, test and measuring equipment.

(It is not designed for use with medical equipment and nuclear energy.)

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

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

 This instrument is protected from electric shock by reinforced insulation. Provide

reinforced insulation between the wire for the input signal and the wires for instrument
power supply, source of power and loads.

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

- If input/output or signal lines within the building are longer than 30 meters.

- If input/output or signal lines leave the building, regardless the length.

 This instrument is designed for installation in an enclosed instrumentation panel. All

high-voltage connections such as power supply terminals must be enclosed in the
instrumentation panel to avoid electric shock by operating personnel.

 All precautions described in this manual should be taken to avoid damage to the

instrument or equipment.
All wiring must be in accordance with local codes and regulations.



 All wiring must be completed before power is turned on to prevent electric shock,

instrument failure, or incorrect action.
The power must be turned off before repairing work for input break and output failure
including replacement of sensor, contactor or SSR, and all wiring must be completed
before power is turned on again.

 To prevent instrument damage or failure, protect the power line and the input/output lines

from high currents with a protection device such as fuse, circuit breaker, etc.



Prevent metal fragments or lead wire scraps from falling inside instrument case to avoid
electric shock, fire or malfunction.

 Tighten each terminal screw to the specified torque found in the manual to avoid electric

shock, fire or malfunction.

 For proper operation of this instrument, provide adequate ventilation for heat

dispensation.

 Do not connect wires to unused terminals as this will interfere with proper operation of the

instrument.

 Turn off the power supply before cleaning the instrument.

 Do not use a volatile solvent such as paint thinner to clean the instrument. Deformation or

discoloration will occur. Use a soft, dry cloth to remove stains from the instrument.

 To avoid damage to instrument display, do not rub with an abrasive material or push front

panel with a hard object.

 Do not connect modular connectors to telephone line.
 When high alarm with hold action is used for Event function, alarm does not turn on while

hold action is in operation. Take measures to prevent overheating which may occur if the
control device fails.

2. MOUNTING

To prevent electric shock or instrument failure, always turn off the power before
mounting or removing the instrument.

2.1 Mounting Environment

(1) The PF900/901 is intended to be used under the following environmental conditions.

 IEC61010-1 OVERVOLTAGE CATEGORY II, POLLUTION DEGREE 2

Indoor use, Altitude up to 2000 m

(2) Use this instrument within the following allowable range:

 Allowable ambient temperature: 10 to 55 C

 Allowable ambient humidity: 5 to 95 %RH

(Absolute humidity: MAX.W.C 29 g/m

(3) Do not use this instrument in the following environment:

 Sudden change in ambient temperature

 Condensation or icing

 Corrosive or inflammable gases.

 Strong vibration or impact

 Water, oil, chemicals, vapor or steam splashes.

 Excessive dust, salt or iron particles.

 Excessive induction noise, static electricity, magnetic fields or noise.

 Direct air flow from an air conditioner.

 Exposure to direct sunlight.

 Direct radiant heat

(4) If this instrument is permanently connected to equipment, it is important to include a switch or

circuit-breaker into the installation. This should be in close proximity to the equipment and within easy

reach of the operator. It should be marked as the disconnecting device for the equipment.

2.2 Mounting Cautions

To avoid problems, consider the following cautions when
mounting the PF900/901:

 Allow space for draft to release heat.

 Make sure to cool down the ambient temperature by using

forced-air cooling system when the ambient temperature
exceeds 55 C. Do not expose this instrument directly to
cool air from the forced-air cooling system.

 Do not mount this instrument directly above equipment

Fresh air inlet

that generates large amount of heat (heaters, transformers,
semi-conductor functional devices, large-wattage
resistors.)

 To improve noise immunity or safety, consider the

following cautions:
High voltage equipment: Do not mount within the
same panel.
Power lines: Separate at least 200 mm.
Rotating machinery: Separate as far as possible.

 Mount PF900/901 within the range of installation position (90).

 Concern the viewing angle of the display when mounting PF900/901.

Viewing angle: Horizontal 90/vertical 90 (contrast ratio 20:1)
