• The equipment must be mounted inside the instrument

panel of a metal enclosure.

• Altitude up to 2000 meters.
• 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.

 

GENERAL PRECAUTIONS

• Before you remove the unit or mount it, turn off the power 

supply and output signal for safety.

• DO NOT set the switches on the module while the power

is supplied.  The switches are used only for maintenance
without the power.

• When heavy dust or metal particles are present in the

air, install the unit inside proper housing with sufficient
ventilation.

• Do not install the unit where it is subjected to continuous

vibration.  Do not subject the unit to physical impact.

• Environmental temperature must be within -10 to +55°C

(14 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.

 

WIRING

• Do not install cables close to noise sources (relay drive

cable, high frequency line, etc.).

• Do not bind these cables together with those in which

noises are present.  Do not install them in the same duct.

 

AND ....

• The unit is designed to function as soon as power is sup-

plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.
