-1RM-E-SET Programmable Cam Switch
Note
• Turn on or off simultaneously the power of the PLC and the power of the FX
2N
-1RM.
• Use an electric wire of 2 mm
2
or more as a power line so that voltage drop can be prevented.
• Even if an instantaneous power interruption of 5 ms or less has occurred, the FX
2N
-1RM
continues its operation.
If a considerably long power interruption or an abnormal voltage drop has occurred, the
FX
2N
-1RM is stopped and the output is turned off. When the power is recovered, the FX
2N
-
1RM automatically restarts operation
(if the RUN/PRG selector switch is set to "RUN").
Cautions on wiring
• Do not connect the AC power supply to DC I/O terminals or DC power terminals.
If such connection is performed, the FX
2N
-1RM may burned out.
• Do not perform wiring from the outside to an unused terminal [
⋅
] of the main unit or an
extension block.
If such wiring is performed, the unit may be damaged.
• Perform Class 3 grounding to the ground terminal in the FX
2N
-1RM or the main unit
using an electric wire of 2 mm
2
or more.
However, do not perform common grounding with a strong electric system.
