Safety Precautions

● Be sure to read the precautions for all E5CC/E5EC-800 models in the website at: http://www.ia.omron.com/.

Do not touch the terminals while power is being

supplied.

Doing so may occasionally result in minor injury due

to electric shock.

Electric shock may occur. Do not touch any cables or

connectors with wet hands.

Electric shock, fire, or malfunction may occasionally

occur. Do not allow metal objects, conductors,

cuttings from installation work, or moisture to enter

the Digital Temperature Controller or the Setup Tool

port or ports. Attach the cover to the front-panel Setup Tool port

whenever you are not using it to prevent foreign objects from

entering the port.

Do not use the Digital Temperature Controller where

subject to flammable or explosive gas. Otherwise,

minor injury from explosion may occasionally occur.

Not doing so may occasionally result in fire. Do not

allow dirt or other foreign objects to enter the Setup

Tool port or ports, or between the pins on the

connectors on the Setup Tool cable.

Minor electric shock or fire may occasionally occur.

Do not use any cables that are damaged.

Never disassemble, modify, or repair the product or

touch any of the internal parts. Minor electric shock,

fire, or malfunction may occasionally occur.

CAUTION - Risk of Fire and Electric Shock

a. This product is UL recognised as Open Type

Process Control Equipment. It must be mounted in

an enclosure that does not allow fire to escape

externally.

b. More than one disconnect switch may be required to de-

energize the equipment before servicing the product.

c. Signal inputs are SELV, limited energy. *1

d. Caution: To reduce the risk of fire or electric shock, do not

interconnect the outputs of different Class 2 circuits. *2

If the output relays are used past their life expectancy,

contact fusing or burning may occasionally occur.

Always consider the application conditions and use

the output relays within their rated load and electrical

life expectancy. The life expectancy of output relays varies

considerably with the output load and switching conditions.

Tighten the terminal screws to the rated torque of

between 0.43 and 0.58 N•m.

Loose screws may occasionally result in fire.

Set the parameters of the product so that they are

suitable for the system being controlled. If they are

not suitable, unexpected operation may occasionally

result in property damage or accidents.

A malfunction in the product may occasionally make

control operations impossible or prevent alarm

outputs, resulting in property damage.

To maintain safety in the event of malfunction of the

product, take appropriate safety measures, such as installing a

monitoring device on a separate line.

*1. An SELV circuit is one separated from the power supply withdouble

insulation or reinforced insulation, that does not exceed 30 V r.m.s. and

42.4 V peak or 60 VDC.

*2. A class 2 power supply is one tested and certified by UL as having the

current and voltage of the secondary output restricted to specific levels.
