19. LOADING AND INSTALLATION
REMARK
As a safety measure, provide a switch for turning on/off the power to each module
and equipment to allow "online I/O module replacement".
(f) Precautions for using 24VDC output of the A62P,A62PEU,A65P or A66P power
supply module
If the 24VDC output power from a single power supply module is insufficient, supply it
from the external 24VDC power supply.
(g) Twist the 100VAC, 200VAC or 24VDC wires as tightly as possible, and use the
minimum length to make connection between modules.
Also, use a thick wire (max. 2 mm
2
) to minimize voltage drop.
(h) Do not install 100VAC and 24VDC wires together with main circuit wires (high
voltage and large current) or I/O signal lines (including common line).Provide a
distance of 100mm (3.94inch) or more between them if possible.
(i) As a measure against lightning surges, connect a lightning surge absorber as
shown below.
CAUTION
Do not connect multiple power supply modules to one module in parallel.
The power supply modules may be heated, resulting in a fire or failure.
