INSTRUCTIONS FOR USE
1. Find the closest earthing point and secure the earthing G-clamp to it.
2. Place the blades on the phases with the aid of the pole.
3. Assure absence of voltage.
4. Connect the equipment cables to the insulated blades with the aid of the pole.
5. To uninstall the equipment, proceed in the reverse order.
6. Store the equipment in its case.
MANTENANCE AND CONSERVATION
Storage:
In order to maintain its ability to protect workers, earthing and short-circuit equipment must be mantained and
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.
