Maintenance - Fuji Electric Micro-Controller X Socket type Operation Manual

If the voltage exceeds 50 V DC (which is called as hazardous voltage), install a basic insulation between all
●
terminals and the ground, and supplementary insulation on the digital outputs.
Note that the insulation class for this equipment is as follows. Before installing, please confirm that the insulation
class for equipment meets usage requirements.
Basic insulation
(1500 V AC)
Power supply (100 to 240 V AC)
Power supply (24 V DC/AC)
Control output 1 (relay contact)
Alarm output 1 and 2 (relay contact)
In case where damage or problems with this equipment may lead to serious accidents, install appropriate external
●
protective circuits.
As this equipment has no power switch or fuse, install them separately as needed.
●
If you install a fuse, be sure to place it between the main power switch and this equipment. (Main power switch:
double-pole breaker, fuse rating: 250V, 1A)
A power switch or a circuit breaker should be installed within the power supply facility.
●
A power switch or a circuit breaker should be properly installed within easy reach of an operator.
●
A power switch or a circuit breaker should be identified as the one for this product.
●
Electrical wiring must be made by the qualified personnel only and in accordance with your local and national
●
standards.
For power supply wiring, use a wire equivalent equal to 600 V vinyl insulated wire or higher level.
●
To prevent damage and failure of the equipment, provide the rated power voltage.
●
To prevent shock and equipment failure, do not turn the power ON until all wiring is complete.
●
Before turning on power, confirm that clearance space has been secured to prevent shock or fire.
●
Do not touch the terminal while the machine is on. Doing so risks shock or equipment errors.
●
