(4) Power supply
(a) Operate the servo amplifier 7kW or less to meet the requirements of the overvoltage category II set
forth in IEC664. For this purpose, a reinforced insulating transformer conforming to the IEC or EN
standard should be used in the power input section.
Since the 11kW or more servo amplifier can be used under the conditions of the overvoltage
category III set forth in IE644, a reinforced insulating transformer is not required in the power
input section.
(b) When supplying interface power from external, use a 24VDC power supply which has been
insulation-reinforced in I/O.
(5) Grounding
(a) To prevent an electric shock, always connect the protective earth (PE) terminals (marked
servo amplifier to the protective earth (PE) of the control box.
(b) Do not connect two ground cables to the same protective earth (PE) terminal Always connect the
cables to the terminals one-to-one.
(c) If a leakage current breaker is used to prevent an electric shock, the protective earth (PE)
terminals of the servo amplifier must be connected to the corresponding earth terminals.
(6) Wiring
(a) The cables to be connected to the terminal block of the servo amplifier must have crimping
terminals provided with insulating tubes to prevent contact with adjacent terminals.
(b) Use the servo motor side power connector which complies with the EN Standard. The EN Standard
compliant power connector sets are available from us as options.
(7) Auxiliary equipment and options
(a) The no-fuse breaker and magnetic contactor used should be the EN or IEC standard-compliant
products of the models described in Section 12.2.2.
(b) The sizes of the cables described in Section 12.2.1 meet the following requirements. To meet the
other requirements, follow Table 5 and Appendix C in EN60204-1.
Ambient temperature: 40 (104) [
Sheath: PVC (polyvinyl chloride)
Installed on wall surface or open table tray
(c) Use the EMC filter for noise reduction.
