Reception

Presentation

Varset is an automatic capacitor bank in the form of:

b panels
b cubicles.

The cubicles can be fitted with harmonic filter reactors.

Reception of equipment

b the addressee is always responsible for the risks and perils of
transporting our goods
b we decline all responsibility for missing items or damage attributable to
the carrier. If need be, send your complaints by registered mail to the carrier
b make sure there are no missing items and that the equipment has not
been subject to a shock likely to have affected its insulation or operation
b check the electrical characteristics indicated on the rating plate
correspond to those on the order form
b in the event of a non-conformity, indicate the shipping note reference
when submitting your complaint.

For A3 cubicles.

DB108741

For A3 bis, A4 and A4 bis cubicles.

Handling

b unpack the equipment at the place where it is to be installed
b it is preferable to use a forklift truck
b for the A3 cubicle, handle in the vertical position using

2 lifting rings
b to handle A3 bis, A4 and A4 bis cubicles in the vertical position, 4 lifting
rings must be used
b avoid shocks and deformation to the equipment.

Storage

b store the devices in a dry and well ventilated place that is sheltered from
rain, water projections, chemical agents and dust
b storage temperature: -20 °C to +45 °C.

Warranty

The equipment is factory cabled and inspected. Any modification to the
equipment jeopardizes its warranty.
