MANTENANCE AND CONSERVATION
Storage:

stored in good conditions by user.
Check before use:
For safety equipment grounding must be subjected to a thorough visual inspection before use. Visible damage of
clamps, fittings, wire insulation or exposure of bare wire are considered major defects and the equipment should
be put out of use.
Before use must inspect the contact surface parts and the contact of the connection points should be brushed to
remove any remaining tank to obtain a good electrical contact for traffic flows or short-circuit currents.
Periodic inspection and testing service:
The equipment must be inspected every 3 years, verifying that there are no visible damage tweezers, or cable
connections.
If there is any doubt about the excellent condition of the device or equipment, should be removed.
