Power Supply - Fuji Electric ZPA Instruction Manual

(1) Power supply

Connect the given power supply to the power terminal, and connect the ground wire to the
grounding terminal. Be sure to perform protective earth connection. Use solderless terminals (for
M4) for connection to the terminals (power and earth).
Please install an accessory ferrite core (To the power supply terminal block side) on the power
supply wiring line of ZPA. Application line diameter ø9.5 to ø10.5

CAUTION
After the wiring work, be sure to put the protective cover on the terminal blocks to ensure safety.
Attention
Après le câblage, veillez à replacer le couvercle de protection sur les borniers pour assurer la
sécurité.

Avoid installing this instrument near an electrical unit (high frequency furnace or electric welder)
that generates much electrical noise. If using the instrument near such a noise generating unit is
unavoidable, use a different power line to avoid noise.

Mount a noise suppressor such as varistor or spark
quencher as shown at right fi gure to the noise generat-
ing unit when noise is generated from relays or solenoid
valves.
Mount the suppressor near the noise generating source, or
it will have no effect.
