Service Conditions
Toshiba medium voltage controllers are intended for usual service conditions as defined by NEMA. The equipment
should not be exposed to corrosive or explosive fumes, dusts, vapors, dripping or standing water, abnormal
vibration, shock, tilting, or other abnormal operation conditions. The temperature of the ambient air surrounding the
controller should be between the limits of 0°C (32°F) and +40°C (104°F). The altitude of the equipment installed
should not exceed 3300 ft. (1000m).
NOTE: Temperature or altitude conditions outside of the usual limits may require derating or other special
equipment, such as heating, cooling, or ventilation. Contact Toshiba for further information.
WARNING
Installation Site Preparation
It is recommended that site preparation be completed before the controller is unpacked, so that possible problems
such as headroom, conduit location, cable tray locations, ventilation, etc. can be solved, assuring a proper
installation in compliance with the building plans and codes. The floor on which the controller will be placed must
be level so that the enclosure is not distorted when bolted in place. Ensure the equipment adequately clears any
underground raceways or cables.
