Key words:
• U: Voltage.
• IPT: Total input power.
• RNC: Running current.
• MC: Maximum current.
NOTE
• Heating conditions: Inlet/outlet water temperature: 30/35 ºC ; Outdoor ambient temperature
(DB/WB): 7/6 ºC
• The compressor data shown in the tables below are based on a combined capacity of 100% of
the power supplied.
• The “Maximum current” shown in the above table is the maximum total unit running current at
the following conditions:
✓ Supply voltage: 90% of the rated voltage.
✓ Unit capacity: 100% at maximum operating conditions.
• The power supply cables must be sized to cover this maximum current value.
• Specications in these tables are subject to change without notice in order that HITACHI may
bring the latest innovations to their customers.
• Please refer to the general information, cautions and notes regarding protective devices (CB,
ELB) throughout the “Electrical and control settings” chapter.
