(3) Environment
(a) Operate the servo amplifier at pollution degree 2 or 1 set forth in IEC/EN 60664-1. For this purpose,
install the servo amplifier in a cabinet which is protected against water, oil, carbon, dust, dirt, etc. (IP54).

[ ] 32 to 131
In storage, in transportation
[ ] 20 to 65

in transportation
90%RH or less
Maximum
altitude
In operation,

1000m or less
In transportation 10000m or less
Note 1. Ambient temperature is the internal temperature of the cabinet.
2. The servo amplifier 200V 3.5kW or less and 100V 400W 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 IEC/EN 60664-1. 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) For the interface power supply, use a 24VDC power supply with reinforced insulation on I/O terminals.
