10.1.2 Safety rules
Performing specialist activities on the equipment,
particularly if the guards need to be dismounted,
exposespeopletoseriousdangerduetothepresence
of potentially live parts.
The rules shown below must be scrupulously followed.
People must always use the Personal Protective
Equipment indicated in the Installation Manual. Dur-
ing activities, unauthorised people may not access
the equipment and WORK IN PROGRESS signs will be
erected in the department in such a way that they
are visible from every place of access.
10. MAINTENANCE
Specialist staff must be authorised and especially
trained concerning the dangers that may arise during
operation and the correct methods for avoiding them.
They must always work with great care and pay full
attention.
If,exceptionally,the staffremoves theguards to
carry out a particular specialist technical mainte-
nance, inspection or repair job, they are required
to put them back after work.
After work, staff must make sure that foreign objects,
in particular mechanical pieces, tools or devices used
during the operative procedure that could cause dam-
age or malfunctions are not left inside the balancer.
For safety, before starting work, maintenance, in-
spection and repair staff must disconnect all power
sources and take all the necessary preventive safety
measures.
As well as operating frequencies, the operations
described below indicate the qualifications that
staff must possess in order to perform the operation.
10.1.3 Replacing fuses
Some protection fuses are located on the power board
(see wiring diagrams) accessible by dismantling the
weight shelf). If fuses require replacement, use ones
with an identical current intensity.
