Mitsubishi Electric FR-CC2-N Series Instruction Manual page 176

• Use a tinned (plating should not include zinc) crimping terminal to connect the earth (ground) cable. When tightening the
screw, be careful not to damage the threads.
For use as a product compliant with the Low Voltage Directive, use PVC cable whose size is indicated on
• A large leakage current flows into the protective earth (ground) conductor. The amount of current leakage from the FR-
CC2 and FR-A872 measures 20 mA at maximum (in AC/DC current measuring range specified in IEC 60990). Do not use
earth (ground) wires smaller than those specified in national and local safety regulations regarding leakage currents.
• Use the molded case circuit breaker and magnetic contactor which conform to the EN or IEC Standard.
• DC current may flow from the converter to a protective earth (ground) conductor. When using a residual current device
(RCD) or residual current monitor (RCM), connect a type B RCD or RCM to the power supply side.
• Use the converter unit under the conditions of overvoltage category II (regardless of the earth (ground) condition of the
power supply), or overvoltage category III (converter units must be used with the earth-neutral system power supply)
specified in IEC 60664.
• To use the converter unit under the conditions of pollution degree 2, install it in the enclosure of IP2X or higher.
• To use the converter unit under the conditions of pollution degree 3, install it in the enclosure of IP54 or higher.
• On the input and output of the inverter and the converter unit, use cables of the size and type set forth in EN 60204-1 or
IEC 60364-5-52.
• The operating capacity of the relay outputs (terminal symbols A1, B1, C1, A2, B2, C2) should be 30 VDC, 0.3 A. (Relay
output has basic isolation from the internal circuit of the inverter and the converter unit.)
• Control circuit terminals on
