MODELR8-SST8■ AND ....
• The unit is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required forsatisfying complete performance described in the datasheet.

INSTALLATION■ HOW TO MOUNT THE MODULE ON DIN RAIL
• I/O ModuleA■ INSTRUCTION MANUALThis manual describes necessary points of caution whenyou use this product, including installation, connection andbasic maintenance procedures.

POINTS OF CAUTION■ CONFORMITY WITH EU DIRECTIVES• The equipment must be mounted inside a panel.
• The actual installation environments such as panel configurations, connected devices, 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 the CE conformity.
• * For example, installation of noise filters and clamp filters for the power source, input and output connected tothe unit, etc..
■ GENERAL PRECAUTIONS• Before you remove or mount the unit, turn off the power
supply and input signal for safety.
• Do not touch the connector while the power is supplied.
Static electricity may cause a malfunction.
• Switches on the side of the module can be set for maintenance only while the power supply is off. Do not accessthem while the power is supplied.

BConfirm that the locking clamps of the I/O module are set.
Insert the module in parallel to the next one while aligning the grooves ofboth modules (A & B in the above figure).
Maintain it perpendicularly to the rail.

More I/O modules can be added in the same manner.

■ ENVIRONMENT• Indoor use.
• When heavy dust or metal particles are present in theair, install the unit inside proper housing with sufficientventilation.
• Do not install the unit where it is subjected to continuousvibration. 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.

R8-SST8■ HOW TO UNMOUNT THE MODULE ON DIN RAIL

• Protective CoverGroove
HookRelease the locking clamps and pull out straight the module.

The protective cover is to be attached over the connected I/O module
at the right end.
Align the hooks on the cover with the grooves of the module and slide itstraight until the hooks are latched.

• Removing an intermediate module

When removing the cover, pull it out while squeezing the hooks inward.

Caution !
1) Be careful not to hurt your hand by pointed edges of the internal busconnector.
2) I/O modules cannot hold tightly on the DIN rail by themselves without
power/network module.
Secure them to the position if necessary by using DIN rail end plates.
