(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).

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
(32 to 113 ) or use the servo amplifier with 75
or less of the effective load ratio.
(4) Power supply
(a) This servo amplifier can be supplied from star-connected supply with earthed neutral point of
overvoltage category
set forth in EN 60664-1. However, when using the neutral point of 400V system
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.
