protection from weather conditions and dirt. Temporary electrical heating should be installed to prevent
condensation. Approximately 150 watts per enclosure is usually adequate.
NOTE: All loose packing or flammable materials should be removed before energizing space heaters.
Outdoor Equipment
An un-energized controller designed for outdoor installation (e.g. Type 3R) should be kept dry internally by
installing electrical heating or by energizing self-heaters, if provided. All openings, either used or unused, should
be covered or sealed to prevent the entry of rain, vermin, insects, etc.
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.
INSTALLATION
Rating Verification - Prior To Installation
The maximum fault capability of the power system at the point of installation should be verified and must not exceed
the short-circuit rating of the controller (see RATINGS section). All system accessories, such as surge suppressers,
lightning arresters, etc., should be checked to verify their ratings capacity.
Do not exceed the ratings specified on the controller nameplate or system accessories.
Location
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. Consult local codes in case more space is required.
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.

If the location for installation is damp, space heaters may be
required. If space heaters (Fig. 5) are furnished inside the controller,
they should be connected in accordance with the wiring 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.
Fig. 5 Typical Space Heater
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.
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, 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.

Mounting
Each shipping section must be leveled and firmly secured to its
supporting foundation. Steel shims may be used for final leveling (Fig. 6),
if necessary. When three or more shipping sections are to be arranged in
one continuous line-up, the center shipping section should normally be
located first.
Follow the equipment outline drawings to determine the location of the
mounting bolt holes and any conduit locations.
Fig. 6 Leveling Using Shims
Various methods may be used to anchor the enclosure to the foundation,
including expandable inserts or “J” bolts embedded in concrete. The
recommended size for anchor bolts is 1/2” (Fig. 7).
For heavy equipment, enclosure must be
securely anchored to prevent tipping over.
Additional Cabinet Entries
If conduit entry locations are required in areas other than the removable
plates, cover the electrical assemblies to prevent metal filings from
becoming lodged in areas which may cause a reduction in the high
voltage clearances or a short circuit. After the work is completed,
thoroughly clean the area and inspect the unit for foreign material.
Fig.7SecurelyAnchortheController
Ground Connections
The controller line-up must be grounded in accordance with
the requirements of the National Electrical Code. Proper
equipment grounding must be established before making
any incoming power connection. If a main ground bus (Fig.
8) is furnished, make the ground connection to this bus. If
there is no ground bus, the sections which are shipped
separately should be connected to ensure a continuous
grounding path.
Each section contains a vertical ground bus extending from
the main ground bus or ground pad to each controller
compartment.

Special attention should be paid to protection for operating personnel, to protection of equipment itself (e.g.
ground fault relays), and protection of sensitive transducers or control devices that are electronic in nature.
The following may be used as a general guide with regard to equipment grounding.
Controller used as service equipment for a grounded system or as a main section for a separately derived
system:
a. The grounding electrode conductor (ground wire) sized in accordance with NEC 250 should be run from the
grounding electrode to the controller ground bus or ground terminal.
b. Unless already done at the factory, a main bonding jumper should be installed from the incoming grounded
connector bus (neutral) to the ground bus or designated grounding point. If a jumper is not furnished, one
having a size in accordance with NEC 250 should be selected.
c. Steps (a) and (b) should effectively connect together the grounding electrode, the controller frame, all
outgoing equipment grounding conductors, and the grounded neutral bus of the system.
d. No connection should be made to ground on the load side of any neutral disconnecting line or any sensor
used for ground fault protection. No connections should be made between outgoing grounding connectors
and the neutral.
e. Where the controller or system is dual-fed (double-ended) and has ground fault protection, special
precautions are necessary to accomplish proper grounding and bonding.
Controller used as service equipment for an ungrounded system or as a main section for a separately derived
system:
a. A grounding electrode conductor (ground wire) sized in accordance with NEC 250 should be run from the
grounding electrode to the controller ground bus or ground terminal.
b. If the system is grounded at any point ahead of the controller, the grounded conductor should be run to the
controller in accordance with NEC 250 and connected to the ground bus or ground terminal.
c. Steps (a) and (b) should effectively connect together the grounding electrode, the controller frame, all
outgoing equipment grounding connectors, and any grounded conductor which runs to the controller.
Controller not used as service equipment or as a main section for a separately derived system, and used on
either a grounded or ungrounded system:
a. The controller frame and any ground bus should be grounded by means of equipment grounding conductors
having a size in accordance with NEC 250 and run with the main supply conductors or by bonding to the
raceway enclosing the main supply conductors in accordance with NEC 250.
