INSTALLATION

WARNING

Do not install this equipment in areas where unusual service conditions exist. Using this equipment in other than usual service conditions can result in equipment failure.

at the installation location, a space heater should be installed inside the circuit breaker enclosure.

NOTE: Temperature, altitude or other conditions outside of the usual limits may require derating or other special equipment. Contact your nearest Toshiba representative for additional

Toshiba HV6FS-MLD circuit breakers are intended for use in usual service conditions as defined in IEEE C37.20.2. The temperature of the cooling air (ambient air temperature) surrounding the breaker should be between the limits of -5°C (23°F) and +40°C (104°F). The altitude of the equipment installation should not exceed 3300 ft (1000 m).

In particular, avoid the following installation conditions:

information.

RATING VERIFICATION

Prior to Installation, the maximum fault current capacity of the power system at the point of installation should be verified. This value must not exceed the symmetrical interrupting capability of the circuit breaker. Fig. 10 illustrates a typical circuit breaker nameplate.

-Excessive dust

-Corrosive gases

-Extreme variations in temperature

-Very high or low humidity

-Vibrations

-Inclined locations

If there is a chance that condensation can occur

DANGER

Do not exceed the ratings specified on the circuit breaker nameplate or system accessories. Underrated equipment can fail during operation causing fire, explosion, severe injury, death, and property damage.
