POINTS OF CAUTION
■CONFORMITY WITH EU DIRECTIVES
• The equipment must be mounted inside a panel.
• 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.
■POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
DC Power supply: Rated voltage 24V DC
24V DC ±10%, approx. 11W
(@ internal power max. current 1.6 A)
Excitation supply (excitation for I/O module):
24V DC ±10%, operational current 8 A
(From power supply (exitation supply) connector, via con-
nector for internal bus, supplied to eacsh I/O module.
Power output current consumption must be under opera-
tional current.)
■GENERAL PRECAUTIONS
• Before you remove or mount the unit, turn off the power
supply and output signal for safety.
■ 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 apply physical impact to the unit.
• Environmental temperature must be within -10 to +55°C
(14 to 131°F) with relative humidity within 30 to90% 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.
■POWER UP
• Turn the power on at the same time as the power/network
module or turn the R8-PS1 on before the power/network
module turned on. If the R8-PS1 is not turned on within 3
seconds after the power/network module is turned on, I/O
modules are not correctly recognized.
INSTALLATION
■HOW TO MOUNT THE MODULE ON DIN RAIL
Confirm that the locking clamps of the extension power supply module
are set. Insert the module in parallel to the next one while aligning the
grooves of both modules (A & B in the above figure).
Maintain it perpendicularly to the rail.
More I/O modules can be added in the same manner.
