4.2 Commercial power supply
Supply commercial power supply shown in 2 to the amplifier.
(1) Power supply
Supply 200 [V] commercial power to the amplifier.
Connect it to terminals L1, L2 and L3.
• Voltage : 200/200-220-230 [V]+10%/−15%. Supply voltage unbalance 3% max.
• Frequency : 50/60 [Hz]
• Phase : 3-phase (main circuit power supply) / single-phase (control power supply)
(2) Power supply capacity
The power supply capacity required for each amplifier is as follows.
The power supply capacity is applied for cabling with specified cable and 20 [m] max. wiring length. If the power capacity is 500[kVA] or more,
AC reactor for impedance matching should be provided. See 10.5.

(3) Higher harmonics suppression
If a (harmonics suppressing) reactor is connected to RYS type amplifier of 3.7 [kW] max., use a “DC reactor”. Refer to 10.7.
(4) Control power supply input
The wiring procedure for control power supply is as follows.
(a) Connector
Use a connector of WSK-L02P type. Refer to 4.1(3) and 10.8 (2)m.
(b) Wiring
Remove the insulation covering of wire by approx. 13[mm] long
and, while strongly pressing the arrow part in the figure by the
operation lever furnished with the connector or flat head
screwdriver, insert the wire.
After connecting 2 wires, engage the connector with the control
power supply and amplifier.
