2.2. Personnel area
The utmost attention is to be paid to the hazards for individuals. There
are various risks and hazards, of these the most important are
mentioned here.
Electric shock
A low-voltage system can produce electrical potentials that can be
dangerous or even fatal for individuals. During work on the system the
following guidelines are to be observed:
a) Work in electrically isolated state
This is the recommended way of working, it should be rigorously
applied during all connection and wiring work. Follow the rules:
1. Electrically isolate
2. Secure against switching back on
3. Short-circuit
4. Connect to earth
5. Report and instruct
After shut down, the short-circuiting of the outputs and earthing are
particularly important if reactive loads or loads that store energy
(accumulators, capacitors, ULTRACAP etc.) are used.
b) Work in the vicinity of live parts
In these circumstances an increased hazard potential is to be
expected. Minimise the risks by means of:
1. Guards
2. Covers
3. Insulating encapsulation, cladding
4. Impose separation by means of mechanical features,
protective grilles.
5. Supervision, reporting
