(Extension base unit for redundant power supply
system)
*1: When using an extension base unit (type requiring no power supply
module), calculate the operating voltage of the unit to check that it is within
the specified range.
1) For the calculation method, refer to the QCPU User's Manual (Hardware
Design, Maintenance and Inspection).
2) For the current consumption of modules mounted on the base unit, refer
to the manual of the corresponding module.
*2: Note the following points when using extension cables.
1) Do not install extension cables together with the main circuit (high
voltage, large current) cables.
2) Connect an extension cable from the OUT of the extension cable
connector of the base unit to the IN of the next extension base unit.
