(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
(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
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)When the servo motor has a power supply lead, use a fixed terminal block to connect it with the servo amplifier. Do not connect cables directly.
