(1) Wiring precautions
To use existing wires of the Q62DA/Q64DA/Q68DAV/Q68DAI, an extra length of
30mm is required for the wiring of an alternative module.
When replacing the module, verify this in the actual system configuration.
(2) Differences between Q62DA/Q64DA/Q68DAV/Q68DAI and
Q62DAN/Q64DAN/Q68DAVN/Q68DAIN
The following shows the differences between the Q62DA/Q64DA/Q68DAV/
Q68DAI and Q62DAN/Q64DAN/Q68DAVN/Q68DAIN.
These modules can be replaced without taking any specific attention except for
the wiring precautions.
