3. | User Information
– Skilled electrician
• Place and attach warning signs and barriers.
• Check the high-voltage system and the high-voltage lines for damage (visual inspection!).
• De-energizing the high-voltage system:
– Switch off ignition.
– Disconnect the service disconnect plug.
– Remove the fuse.
– Disconnect the ground side of the 12-V vehicle electrical system.
• Regard the vehicle manufacturer's instructions.
• Securing the high-voltage system against re-activation:
– Withdraw the ignition key and keep it safe.
– Keep the service disconnect plug in a safe place or secure the battery master switch against re-activation.
– Insulate the battery master switch, the plug connections etc. with dummy plugs, covering caps or insulating tape
with the corresponding warning notice.
• Use a voltage tester to make sure that the vehicle is de-energized. Even if the high-voltage system is deactivated,
some residual voltage may still be present.
• Ground and short-circuit the high-voltage system (necessary only if voltage is higher than 1000 V).
• Voltage below 1000 V: Cover the parts which are close to the system or which are energized e.g. with insulating cloth,
hoses or plastic coverings. Voltage higher than 1000 V: Cover the parts with insulating plates/protective panels spe-
cially developed for this purpose so that sufficient protection against contact to adjacent parts is ensured.
• Regard the following before re-energizing the high-voltage system:
– All tools and utilities are removed from the hybrid/electric vehicle.
– Remove the grounding and short circuit of the high-voltage system. Do not touch any of the cables now.
– Attach the protective paneling that has been removed before.
– Remove the protective measures at the switching system.
3.1.5. Safety Precautions for Testing/Measuring Devices
• Perform measurements only on electric circuits that are not directly connected to the line voltage.
