Type of test
For the operation at constant current,
the safe disconnection of the high
voltage electricity supply must be
tested.

Other tests
These tests must be carried out periodically The following maximum intervals between tests are
(see § 7.2.3 table 4 in standard EN 50177).
Complete installation safety test in relation to workers
Forced ventilation effectiveness
Disconnection in the event of an overload current
Low voltage disconnection
Discharge energy
Protection against cleaning product inflammation
Protection against direct contact
Earthing measures
Protection against inputs
Site's fire extinguishing system
Other tests
See 5.2.2 and 5.2.2.2 in standard EN50177
The disconnection threshold Iü must be defined and documented in relation to the
operational and local conditions. Checks must be carried out to ensure that the
high voltage is disconnected if the high voltage falls unacceptably below the
disconnection threshold Umin. In this context, the disconnection threshold Umin
defined during the initial test must be checked.
A disconnection threshold Umin that may increase the possibility of dangerous
discharges or electrical flashovers between the parts under high voltage and the
grounded parts if the safe distance falls below its permitted value is not permitted.

In addition to the location's protection system, local fire extinguishing systems
(fixed and dedicated to the object)) must provide effective protection for the
local
fire
dangerous zone located between the output from the coating powder and the
part to be processed. It must be proven for each individual case that the roles of
the local fire extinguishing systems and the location's protection systems may be
satisfied by a single extinguishing system.
