. accordance with 60529 and include all parts the test object. Opening the means protection must disconnect the test
voltage automatically.ERECTION AND OPERATION ELECTRICAL TEST EQUIPMENT

11.g. The means protection against direct contact shall guarantee least the defined
degree protection IP3X.
It shall not possible switch the test voltages until the means protection are fully
operational and functioning correctly. due arcs, noise, explosion, radiation, flying
parts, formation gas, fire, dangerous substances. Test stations without automatic protection against direct contact
Test stations without automatic protection against direct contact shall only installed the
erection test station with automatic protection against direct contact not practicable, e.5.g.
Single fault conditions shall not prevent the test voltages from being switched off when the
means protection are opened.3.4 Protection against residual voltages and transfer voltages
If there likelihood danger due residual voltages after switching-off test circuits,
suitable devices equipment shall provided for safe discharge energy.2 Preventing unauthorised and unintentional switching -on
Test equipment shall secured against unauthorised and unintentional switching-on test
circuits.
11.
Protective measures against other hazards
Appropriate means protection shall provided, cases where addition dangers due
to voltages other hazards are expected, e.
.
11. Test stations with automatic protection against direct contact
The protection against direct contact must satisfied insulation live parts, covers or
enclosures. must not possible bypass the means protection an
easy way.
11.
Mechanical means protection shall adequately strong.4.
Transfer voltage accessible conductive parts outside the test area shall prevented by
adequate measures e. The occurrence the fault shall ensure that impossible to
switch the test voltages again.3.
In the case test station with automatic protection against direct contact, barriers and
emergency switching off devices may omitted.
11. Manual controls shall clearly correlated the respective test circuits.3.3 Preventing automatic energizing
Automatic energizing test circuits shall prevented when mains voltage recovers after a
power failure. Residual voltages shall automatically reduced non-hazardous level
before live parts can touched.g. earthing, shielding, appropriate cable routing these conductive parts
shall protected against direct contact
