• The charging tray and the mega macs X become warm during the inductive charging process. This is due to the
charging principle.
• The diagnostic device is equipped with a cooling system. The corresponding vent slots must not be covered (fire haz-
ard).
• If the diagnostic device shows signs of malfunction, contact Hella Gutmann or your trading partner immediately.
3.1.4. Safety Precautions for High Voltage/Line Voltage
Very high voltages occur in electrical systems. Due to voltage flashover on damaged components, such as marten dam-
age or touching live components, the risk of electric shock is likely. High voltage via the vehicle and line voltage via the
building's mains supply can cause severe injury or even death if adequate care is not taken. Voltage flashover can occur
e.g. on the primary and secondary side of the ignition system, the connection to the vehicle, the lighting systems or the
wiring harness with plug connections. Therefore regard the following:
• Only use power supply cables with grounding contact.
• Only use a checked or the attached power cord.
• Always use the original cable set.

Hella Gutmann User Information | 3.
mega macs X 11
• Regularly check cables and adapters for damage.
• Perform any assembly work such as the connection of the diagnostic device to the vehicle or the replacement of com-
ponents only when ignition is switched off.
3.1.5. Safety Precautions for Hybrid/Electric Vehicles
Very high tensions occur on hybrid and electric vehicles. Due to voltage flashover on damaged components, such as
marten damage or touching live components, the risk of electric shock is likely. High voltage at or in the vehicle can lead
to death in case of inattention. Therefore regard the following:
• Only the following qualified employees are allowed to de-energize the high-voltage system:
– High-voltage technician
– Skilled electrician for predetermined operations – Hybrid or rather electric vehicles
– 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.
• Test for absence of voltage with a voltage tester.
• Ground and short-circuit the high-voltage system (necessary only if voltage is higher than 1000 V).

3. | User Information Hella Gutmann
12 mega macs X
• 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.
3.1.6. Safety Precautions for Testing/Measuring Devices
• Perform measurements only on electric circuits that are not directly connected to the line voltage.
• Never exceed the maximum permissible voltage load of 42 V peak alternating voltage (AC) or 60 V direct current volt-
age (DC) respectively.
• Do not exceed the voltage limits indicated on the connecting cables.
• The voltage values to be measured must be shielded extra or even twice from dangerous line voltage. The voltage
limits printed on the test leads must not be exceeded. Pay attention that the allowed measuring range of 60 V/DC / 42
V peak is not exceeded when measuring positive and negative voltage at the same time.
• Never perform measurements on ignition systems.
• Regularly check the test and measuring devices for damage.
• Always connect the test and measuring devices to the measurement module (MT-USB) first.
• Do not touch the connections/measurement points during the measurement.
