(2) Configuration
The control circuit provide safe separation to the main circuit in the converter unit and servo amplifier (drive
unit).

(3) Environment
Operate the converter unit and servo amplifier (drive unit) at or above the contamination level 2 set forth in
IEC60664-1. For this purpose, install the servo amplifier in a control box which is protected against water,
oil, carbon, dust, dirt, etc. (IP54).
(4) Power supply
(a) This converter unit and servo amplifier (drive unit) can be supplied from star-connected supply with
earthed neutral point of overvoltage category III set forth in IEC60664-1. However, when using the
neutral point of 400V system for single phase supply, a reinforced insulating transformer is 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 ) of the
converter unit and servo amplifier (drive unit) to the protective earth (PE) of the control box.
