  • Page 29: Enclosure Design

    Tab. 2-1: Environmental standard specifications of inverter Temperature The permissible ambient temperature of the inverter FR-E700 is between −10 and +50°C. Al- ways operate the inverter within this temperature range. Operation outside this range will con- siderably shorten the service lives of the semiconductors, parts, capacitors and others. Take the following measures so that the ambient temperature of the inverter falls within the specified range.
  • Page 30 Enclosure design Installation Humidity Normally operate the inverter within the 45 to 90% range of the ambient humidity.
