■ 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 EC DIRECTIVES
• The equipment must be mounted inside the instrument
panel of a metal enclosure.
• The actual installation environments such as panel con-
figurations, connected devices and connected wires may
affect 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 CE conformity.
■ HOT INSERTION/REMOVAL OF MODULES
Removing or replacing modules does not affect other mod-
ules 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 ven-
tilation.
• 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 sup-
plied, however, a warm up for 10 minutes is required for sat-
isfying complete performance described in the data sheet.
