APPENDIX
(2) Structure
The control circuit provide safe separation to the main circuit in the servo amplifier.
(3) Environment
(a) Operate the servo amplifier at pollution degree 2 or 1 set forth in EN 60664-1. For this purpose, install
the servo amplifier in a cabinet which is protected against water, oil, carbon, dust, dirt, etc. (IP54).
(b) Environment
(4) Power supply
(a) This servo amplifier can be supplied from star-connected supply with earthed neutral point of
overvoltage category
for 1-phase supply, a reinforced insulating transformer is required in the power input section.
(b) For the interface power supply, use a 24VDC power supply with reinforced insulation on I/O terminals.

Note 1. Ambient temperature is the internal temperature of the cabinet.
2. The servo amplifier 200V 3.5kW or less can be mounted closely. In this case, keep the
ambient temperature within 0 to 45
or less of the effective load ratio.
