INSTRUCTION MANUAL

This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.

POINTS OF CAUTION

■

CONFORMITY WITH EU DIRECTIVES

• This equipment is suitable for Pollution Degree 2, Instal-

lation Category II (AC power, transient voltage 2500V)
and Measurement Category II (output, transient voltage
2500V). Basic insulation (signal input to output to power:
300V) is maintained. Prior to installation, check that the
insulation class of this unit satisfies the system require-
ments.

• Altitude up to 2000 meters.
• The equipment must be mounted inside a panel.
• The equipment must be installed such that appropriate

clearance and creepage distances are maintained to con-
form to CE requirements. Failure to observe these re-
quirements may invalidate the CE conformance.

• The actual installation environments such as panel con-

figurations, connected devices, connected wires, may af-
fect the protection level of this unit when it is integrated
in a panel system. The user may have to review the CE
requirements in regard to the whole system and employ
additional protective measures to ensure the CE conform-
ity.

• In order to enable the operator to turn off the power in-

put immediately, install a switch or a circuit breaker ac-
cording to the relevant requirements in IEC 60947-2 and
properly indicate it.

• Install lightning surge protectors for those wires connect-

ed to remote locations.

■

GENERAL HANDLING

1) Keep away from the following environments when in-

stalling the unit.

• Where the ambient temperature in operating the unit

may reach beyond the range of -10 to 55°C or 14 to 131°F.

• Where the relative humidity in operating the unit may

reach beyond 30 – 90% RH.

• Rapid temperature change or condensation

• Corrosive gases, sulfide and ammonia in particular, or

flammable gases

• Vibration or mechanical shock
• Direct contact with water, oil, chemical materials, steam

or vapor

• Exposure to air containing heavy dust particles, salt,

chemical components, or iron particles.

• Interference by static and magnetic noise
• Direct sunlight
• Heat accumulated by radiation or such

2) Mounting the unit
Push in the mounting bracket from behind the panel un-

til the main body is securely fit on to the panel surface.

If there remains a play, tighten lightly the two screws to

stabilize the unit. Do not tighten too much because the

mounting bracket may be off the stopper by such force.

■

WIRING CONNECTION

1) Where the external wiring is subjected to noise interfer-

ences, protect the unit as follows:

• For connecting a contactor employed as load of alarm out-

puts, attach a surge absorber to the contactor on the coil
side.

• An additional installation of isolating transformer and

use of noise filter are recommended when an excessive
noise exists in the power supply.

• Make sure that the noise filter is installed to a properly

grounded panel or such place and that the wiring be-
tween the output side of the filter and the power supply
terminals of the unit is made as short as possible.

• Do not install a switch or fuse on the output side of the

filter because it will degrade effectiveness of the filter.

• Stranded power supply wires are effective for protection

against noise. Better result will be expected with shorter
stranding pitch.

2) The contact outputs require a set-up time when the pow-

er is turned on. If they are to be used for an external

interlock circuit, add ON-delay relay.

3) Keep input signal and power wiring to the unit away

from power supply or load lines in order to avoid induc-

tive noise interference.

Use shielded wires for input signal line and separate

them from other wires.
