Note. Servo amplifiers of 22kW or less do not have a converter unit.
(3) Environment
(a) Operate the converter unit and servo amplifier (drive unit) at or above pollution degree 2 set forth in
IEC/EN 60664-1. For this purpose, install the servo amplifier in a control box which is protected against
water, oil, carbon, dust, dirt, etc. (IP54).

Note 1. Ambient temperature is the internal temperature of the control box.
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 converter unit and servo amplifier (drive unit) 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.
(5) Grounding
(a) To prevent an electric shock, the protective earth (PE) terminal (marked
) of the converter unit, servo
amplifier (drive unit) must be connected to the protective earth (PE) of the control box.
