Revision 5.0
fig. 82
To supply power to the units and the I/O devices, connect the power supply
wires to the power supply terminals of the GRT1-ML2. If the wire ends have
pin terminals, just insert the pin terminals in the power supply terminals.
fig. 83
To remove the wires, press the release button above the terminal hole with a
precision screwdriver, and pull out the wire.
It is recommended to use a SELV (Safety Extra Low Voltage) power supply
with over-current protection. A SELV power supply has redundant or
increased insulation between the I/O, an output voltage of 30 V rms and a
42.4 V peak or maximum of 60 VDC.
Recommended power supplies are:
•
S82K-01524 (OMRON)
•
S8TS-06024 (OMRON).
It is recommended to use wires with a gauge of 20 AWG to 16 AWG (0.5 to
1.25 mm
2
).
Strip the wire between 7 and 10 mm of insulation at the ends of the wires
(stranded or solid wire), or use pin terminals with a pin (conductor) length of
8 to 10 mm.
