■INSTRUCTION MANUAL

This manual describes necessary points of caution when

you use this product, including installation, connection and

basic maintenance procedures.

POINTS OF CAUTION

■HOT SWAPPABLE MODULES

• Replacing the module does not affect other modules on

the same base. Thus, the module can be replaced while

the power is ON. However, replacing multiple modules

at once may greatly change live voltage levels. We highly

recommend to replace them one by one.

■GENERAL PRECAUTIONS

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

is supplied. The switches are used only for maintenance

without the power.

■ENVIRONMENT

• Indoor use.

• 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.
