Routine Inspection
Routine scheduled inspection should be established if storage for an extended period is
anticipated. This is to check for condensation, corrosion, vermin, and adequacy of space
heating. Prior to inspection, the equipment should be carefully examined for evidence of
physical damage, corrosion, or other deterioration.
Do not install equipment found to have damage or
deterioration that could affect the unit performance.
Overhead should be checked for plumbing condensation, sprinklers or similar possible
sources of trouble. A clearance of 1/2 inch should be provided between a wall and the rear
of the controller for indoor equipment, when rear access is not required. If rear access is
required in either environment, a minimum of 30 inches should be provided. A minimum
of 48 inches working space should be allowed in front of the controller. This minimum
should be increased if necessary to accommodate movement around open enclosure
doors to comply with applicable codes.
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.
If the location for installation is damp, space heaters may be required. If space heaters
are furnished inside the controller, they should be connected in accordance with the wir-
ing diagram furnished.
Do not install this equipment in areas where unusual service
conditions exist, unless the equipment has been specially
designed for the particular environment.
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, ven-
tilation, 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.
