2.4 Cautions for Power Supply from Q61P-A1/A2 to Q64AD-GH
When using the Q61P-A1/A2 and Q64AD-GH in combination, it is required to use them
within the range in Table 2.1.
This requirement applies to the case where the Q64AD-GH satisfies any of the
following conditions.
The first six digits of serial number are "050914" or earlier.
The first five digits of "Product information" number are "05081" or earlier.
If it satisfies the above conditions but does not meet the ones outlined in Table 2.1,
carry out the following:
Replace the power supply module with the Q64P.
Mount the Q64AD-GH to another base unit.

No. of Q64AD-GH
modules
Conditions
Available power supply
Q61P-A1/A2 Q64P
3 or less
Total current consumption of all modules on the same
base is 5.0A or less.
Total current consumption of all modules on the same
base exceeds 5.0A.
4
Module other than the Q64AD-GH is not mounted on
the same base.
Module other than the Q64AD-GH is mounted on the
same base.
5 or more
—
1: If the modules are used outside the condition range given in Table 2.1, the "POWER" LED
of the power supply module may flash*/ and the programmable controller CPU system may
not start up.
REMARK
When the Q64AD-GH satisfies any of the following conditions, the above precaution
does not apply.
The first six digits of serial number are "051217" or later.
The first five digits of "Product information" number are "05082" or later.
