FX Supervisory Controller Installation Instructions 3
Static Discharge Precautions
Static charges produce voltages high enough to
damage electronic components. The microprocessors
and associated circuitry within a FX20/FX60 are
sensitive to static discharge.
IMPORTANT: Work in a static-free area. Discharge
any static electricity you may have accumulated.
Discharge static electricity by touching a known,
securely grounded object. Do not handle the Printed
Circuit Board (PCB) without proper protection
against static discharge. Use a wrist strap when
handling PCBs. Secure the wrist strap clamp to
earth ground.
Accessories
The FX20/FX60 has a 20-pin, right-angle, Euro-DIN
connector that accepts accessory modules. The
connector provides power and signal lines to any
connected modules. The connector is located on the
end of the FX20/FX60 opposite the option cards.
IMPORTANT: Turn off power to the FX20/FX60
before inserting or unplugging accessory modules.
Wait for the LED activity to stop (all LEDs off).
!
CAUTION: Risk of Property Damage.
Do not apply power to the system before checking
all wiring connections. Short circuited or improperly
connected wires may result in permanent damage to
the equipment.
MISE EN GARDE: Risque dégâts matériels.
Ne pas mettre le système sous tension avant d'avoir
vérifié tous les raccords de câblage. Des fils formant
un court-circuit ou connectés de façon incorrecte
risquent d'endommager irrémédiablement
l'équipement.
Each accessory module has a DIN-mount base, and
typically provides two 20-pin connectors that allow you
to chain multiple accessories (see DIN Rail Mounting
Instructions). Table 1 lists the currently available
modules.
