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

In transportation 10000m or less
Note 1. Ambient temperature is the internal temperature of the control box.
2. The driver 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 driver
with 75 or less of the effective load ratio.
(4) Power supply
(a) This driver (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 driver (drive unit)
must be connected to the protective earth (PE) of the control box.
