Fuji Electric B3HU series component identification and points of caution.

The following are general precautions when using this unit. The safety features and precautions specific to the hazardous locations are explained in “Safe Installation Manual” for each certification.

CONFORMITY WITH EC DIRECTIVES.
- Functional insulation is maintained between the input and output.
- The equipment must be mounted inside a panel.
- The actual installation environments such as panel configurations, connected devices, connected wires, may affect the protection level of this unit when it is integrated in a panel system. The user may have to review the CE requirements in regard to the whole system and employ additional protective measures to ensure the CE conformity.

SAFETY PRECAUTION.
- Before you remove the unit or mount it, turn off the power supply and input signal for safety.

ENVIRONMENT.
- Indoor use
- When heavy dust or metal particles are present in the air, install the unit inside proper housing with sufficient ventilation.
- Do not install the unit where it is subjected to continuous vibration. Do not subject the unit to physical impact.
- Environmental (non-hazardous location) temperature must be within -40 to +85°C (-40 to +185°F) with relative humidity within 0 to 95% RH in order to ensure adequate life span and operation.
- Be sure that the ventilation slits are not covered with cables, etc.

WIRING.
- Do not install cables (input and output) close to noise sources (relay drive cable, high frequency line, etc.).
- Do not bind these cables together with those in which noises are present. Do not install them in the same duct.

AND ....
- The unit is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required for satisfying complete performance described in the data sheet.
