Section 2. Considerations before Installation
Refer to Figure 1-2 in Section 1 for the dimensions of the compressor.
Figure 2-1 Required space for compressor installation (scale: mm) and
levelness
2.2 Wiring requirements
Table 2-1 shows the specifications of optional input power cables. For connecting
procedures of the input power cable refer to “Section 4.6 Electrical connections”.

cables are attached to the compressor.
Supply AC power for compressor from the equipment-side distribution panel. The
distribution panel should have branched circuit breakers for each compressor (see Figure
2-2). Circuit breakers must be appropriate and meet the international and the national
codes and standards of the country installed (Refer to UL489 and IEC60947-2). Also,
circuit breakers must be installed in the distance to be able to check the compressor.
Refer to Table 1-2 in section 1 for circuit breaker current rating.

CAUTION
In most standards, it is required to install a branch breaker to protect power cables connected
to the equipments. A circuit breaker must be installed. Failure to follow this procedure could
seriously damage the equipment.
