POINTS OF CAUTION

■ HOT INSERTION/REMOVAL OF MODULES

Removing or replacing modules does not affect other modules

on the same backplane. It is possible to replace them without

removing the power supply. However, replacing multiple

modules at once may greatly change line voltage levels. We

recommend that you replace them one by one.

■ ENVIRONMENT

• Indoor use

• When heavy dust or metal particles are present in the air,

install the unit inside proper housing with sufficient ventila-

tion.

• 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 (power supply, input and output) 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

supplied, however, a warm up for 10 minutes is required for

satisfying complete performance described in the data sheet.
