Power supply modules Wiring of power supply modules
7 – 8
NOTES Ground the LG and FG terminals to the protective ground conductor.
Check the rated voltage and terminal layout of the power supply carefully, before wiring.
When one of the redundant power supplies Q63RP or Q64RP fails or when the input voltage
of one power supply shuts off, the other one takes over the whole power supply. Specify your
redundant system, that the capacity of one power supply is sufficient for the power consum-
tion of all modules.
When using two power supplies per base unit, the input voltage should be separated with
separate fuses, contactors etc. For replacement of one power supply due to failure or main-
tenance, each power supply should be switched off separately.
The internal fuse of the power supplies can’t be replaced by the user. Please contact your
local Mitsubishi service center or representative for replacing.
Use the output contact ERR
to indicate a failure. Only wire this output when needed. The
maximum cable length must not exceed 30 m.
The output contact ERR
has no function (always off) when the power supply is mounted on
an extension base unit.
Do not input a voltage of 200 to 240 V AC into the Q61P-A1 or a voltage of 100 to 120 V AC
into the Q61P-A2.
The Q64P and Q64RP automatically recognize the rated input voltage waveform to switch
the input voltage between 100 to 120 V AC and 200 to 240 V AC. Input voltages from 85 to
132 V AC and 170 to 264 V AC are possible.
Q64P and Q64RP are not compatible with the intermediate voltage (133 to 169 V AC).
The maximum cable length for the LIFE OUT
contact must not exceed 30 m.
