(a) Cautions for using the extension base unit (Q5 B)
When Q5 B is used, a power of 5VDC is supplied from the redundant power
supply module on the redundant power main base unit (Q3 RB) through an
extension cable.
Pay attentions to the following to use Q5 B.
• Keep the sum of the current consumption on Q3 RB and Q5 B not
exceeding the 5VDC rated output current for one redundant power supply
module.
• Because 5VDC is supplied to Q5 B through an extension cable, voltage
drop occurs in the extension cable.
Select an appropriate extension cable so that a voltage of 4.75VDC or more
is supplied at the "IN" connector of Q5 B.
For details of the voltage drop, refer to Section 6.1.4.
(b) Methods for reducing voltage drops
The following methods are effective to reduce voltage drops at the extension
cables.
1) Changing the module loading positions
Mount a module with large current consumption on the redundant power main
base unit (Q3 RB).
Load small current consumption modules on the extension base unit (Q5 B).
2) Using short extension cables
The shorter the extension cable is, the smaller the resistance and voltage
drops are.
Use the shortest possible extension cables.
(4) When the base unit is QA1S6 B:
Select the power supply module also in consideration of the current consumption of
the peripheral devices connected to the special function module.
For example, when the AD75TU is connected to the AD75P1-S3, the current
consumption of the AD75TU must also be taken into account.
