The total power consumption for each Rack can be obtained from the following
formulas:
• CPU Rack: Total power consumption for each Unit + 7 (8)
Where:
7 = Power consumption of the CPU Unit,
(8) = Power consumption of the CPU21-E/23-E,
0.6 = 60% efficiency, and
0.55 (1) = Power rate (Number in parentheses: when CPU31-E is used.)
• Expansion I/O Power Supply/Remote I/O Slave Unit:
Total power consumption for each Unit + 2
Where:
2 = Power consumption of the I/O Power Supply or
Remote I/O Slave Unit,
0.6 = 60% efficiency, and
0.55 (1) = Power rate (Number in parentheses: when
PS211, RT002-P or RT202 is used.)
Connect the I/O Devices to the I/O Units using AWG 22 (cross-sectional area of
2
0.3 mm ) for 19-terminal terminal blocks and AWG 22 to AWG 18 lead wire
(cross-sectional area of 0.3 to 0.75 mm
terminals have screws with 3.5-mm diameter heads and self-raising pressure
plates. Connect the lead wires to the terminals as shown below. Tighten the
screws with a torque of 0.8 N S m.

Use 1.25-mm cables or larger. The terminal blocks have screws with 3.5-mm
diameter heads and self-raising pressure plates. For connecting to the terminal
blocks, use round crimp terminals for 3.5-mm diameter heads. Directly connect-
ing stranded wires to the terminal blocks may cause a short-circuit.
Tighten the terminals on the terminal blocks to the torque of 0.8 N S m.
