Меры предосторожности при работе с электрооборудованием (Дискавери 3)

General

The following guidelines are intended to ensure the safety of the operator whilst preventing damage to the electrical and electronic components of this vehicle.

Equipment

Prior to commencing any test procedure on the vehicle, ensure that the relevant test equipment is working correctly and that any harness or connectors are in good condition. It is particularly important to check the condition of all plugs and leads of mains operated equipment.

Polarity

Never reverse connect the vehicle battery and always ensure the correct polarity when connecting test equipment.

High voltage circuits

Whenever disconnecting live ht circuits, always use insulated pliers and never allow the open end of the ht lead to contact other components, particularly ECU's.

Vehicles fitted with Bi-Xenon headlamp bulbs

ПРЕДОСТЕРЕЖЕНИЕ: The following precautions must be observed as failure to comply may result in exposure to ultra-violet rays, severe electric shock, burns or risk of an explosion.

• Safety goggles and gloves must be worn.
• Ensure that headlamps are switched off before removing bulbs.
• Do not touch the glass portion of the bulb.
• On no account should headlamps be switched on with the bulb removed from the headlamp.
• Bulb testing may only be carried out with the bulb fitted in the headlamp.
• Bulbs must be disposed of in accordance with the local authority bye-laws.

Connectors and harnesses

The engine compartment of a vehicle is a particularly hostile environment for electrical components and connectors. Always observe the following:

• Ensure electrically related items are dry and oil free before disconnecting/connecting test equipment.
• Ensure that disconnected multiplugs and sensors are protected from any possible oil, coolant or other liquid contamination. Any such contamination could impair performance or lead to component failure.
• Never force connectors apart or pull on the wiring harness.
• Always ensure locking tabs are disengaged before disconnecting multiplugs etc. and ensure that correct orientation is achieved before connection.
• Ensure that any protection covers, insulation etc. are replaced if disturbed.

Having confirmed that a component is faulty, carry out the following:

• Switch off the ignition and disconnect the battery.
• Remove the component and support the disconnected harness.
• When replacing electrical components, keep oily hands away from electrical connections and ensure that locking tabs on connectors are fully engaged.

Battery Disconnection/Connection

Always refer to the Electrical Section of this manual - Battery Connection/Disconnection prior to attempting to connect or disconnect the battery. Для получения дополнительной информации обратитесь к Specifications (414-00 Charging System - General Information)
