Mitsubishi Electronics MDS-D-SVJ3 ユーザーズマニュアル

Appendix 3 - 3

Use the units under an Overvoltage II (MDS-D, MDS-D-SVJ3/SPJ3) and Pollution Class of 2 or less 

environment as stipulated in IEC60664. 

(a) To adjust the units to the Overvoltage Category II, insert an isolating transformer of the star connection 

complying with EN or IEC standard in the input of the power supply unit.

(b) To adjust the units to the Pollution Class of 2, install the units in a control panel having a structure (IP54 

or higher) in which water, oil, carbon or dust cannot enter.

[1] Use the power supply and servo/spindle drive unit under an Overvoltage Category II (MDS-D, MDS-D-

SVJ3/SPJ3) as stipulated in IEC60664.

[2] Earth the PE terminal of the units to the neutral point of the star connection.

[3] Do not omit the circuit breaker and electromagnetic contactor.

[1] To prevent electric shocks, always connect the servo/spindle drive unit protective earth (PE) terminal 

(terminal with 

 mark) to the protective earth (PE) on the control panel.

[2] When connecting the earthing wire to the protective earth (PE) terminal, do not tighten the wire 

terminals together. Always connect one wire to one terminal.

[1] Always use crimp terminals with insulation tubes so that the connected wire does not contact the 

neighboring terminals.

[2] Do not connect the wires directly.

[3] Always install the power supply unit and servo/spindle drive unit on the metal panel.
