By using different power supply systems for the power supply modules
on the bases, the following advantages are available.
Even when the power supply module on either of the bases goes down,
only the faulty power supply module can be powered off without
powering off other power supply modules.
Also, when all the power supply modules on the main base should be
powered off, if the power supply of the extension base is remained ON,
output signals of the extension base can be retained by the output hold
mode function.
POINT
(1) Use the thickest possible (max. 2 mm
2
(14 AWG)) wires for the 100/200
VAC and 24 VDC power cables. Be sure to twist these wires starting at
the connection terminals. For wiring a terminal block, be sure to use a
solderless terminal. To prevent short-circuit due to loosening screws,
use the solderless terminals with insulation sleeves of 0.8 mm (0.03
inch) or less thick. The number of the solderless terminals to be
connected for one terminal block are limited to 2

(2) When connection is made between the LG and FG terminals, be sure to
ground the wire.
When it is not grounded with LG and FG terminals connected, it will be
susceptible to noise.
Note that each LG terminal has half the potential of the input voltage;
you might get an electric shock if you touch it.
4.4 Precaution when Connecting the Uninterruptive Power Supply (UPS)
As for UPS, use the online power system or online interactive system with a
voltage distortion rate of 5% or less.
For the UPS of the commercial online power system, use Mitsubishi Electric's F
Series UPS (serial number P or later) (Ex.: FW-F10-0.3K/0.5K).
Do not use any UPS of the commercial online power system other than the F
series mentioned above.
