(4)Power supply

(a)Operate the servo amplifier 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.

(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 ) of the 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.

PE terminals PE terminals

(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 14.2.2.

(b)The sizes of the cables described in Section 14.2.1 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.

(8)Performing EMC tests

When EMC tests are run on a machine/device into which the servo amplifier has been installed, it must conform to the electromagnetic compatibility (immunity/emission) standards after it has satisfied the operating environment/electrical equipment specifications.

For the other EMC directive guidelines on the servo amplifier, refer to the EMC Installation Guidelines(IB(NA)67310).
