19. LOADING AND INSTALLATION
(1) Wiring the power supply
(a) When voltage fluctuates outside the specified value range, connect a constant-
voltage transformer.
(b) Use a power supply which generates minimal noise between wires and between
the PLC and ground.
If excessive noise is generated, connect an isolating transformer.
(c) When using a power transformer or an isolating transformer to reduce the
voltage from 200VAC to 100VAC, its capacity must be equal to or greater than
the corresponding value shown in the following table.
(d) Separate the PLC's power supply line from the lines for I/O devices and power
devices as shown below.
When there is much noise, connect an isolating transformer.
(e) Taking rated current or inrush current into consideration when wiring the power
supply, be sure to connect a breaker or an external fuse that have proper blown
and detection.
When using a single PLC, a 10A breaker or an external fuse are recommended
for wiring protection.
