4.2.1.
SAFETY CIRCUIT
The voltages and currents generated by the SEFELEC1500M measurement devices can create
a risk of electric shock by contact. Protection for the personnel is the responsibility of the man-
agement of the site where the measuring device is installed.
EATON can only provide recommendations. The "safety" manager of the company using the
device is responsible for ensuring compliance with the safety measures.
The devices have a
double safety circuit
to meet the requirements of CEI 61010-2-034,
EN60591, either intrinsically or by the addition of external accessories (emergency stop buttons,
light curtains, beacons, safety cages, etc.).
This double safety circuit has electromechanical relays to cut the high voltage generators as
soon as one of the circuits is open. The test software raises an alarm message and stops the
test. The circuits must be re-established and an operator command given before the test can
continue.
The indicators on the front panel and an optional beacon show that the measuring device is on
(green) and that the measuring device is testing (red).
Connecting the safety circuits
The device has a double "safety circuit" available on points 1-9 and 2-10 of the rear socket C5.
The latter must be connected in order to authorise the execution of a test.
Note: it is recommended that you place in these connections dry contacts in series subject to
safety conditions (closed door, cover lowered, etc.).
It is possible to connect a red/green signal lamp (SEF-CO160) on terminal plug C5 in order to
visibly indicate at a distance the presence or absence of voltage on the output terminals of the
device.
NOTE
the connection of the connector C5 is given in paragraph 17.1.1:
SAFETY CONNECTOR C5
Reminder of the standard: Contact with live parts
The effects of a current passing through the human body have been studied and are covered in
NF EN 50191 of 20 January 2003, available from AFNOR. It applies to "
the installation and op-
eration of electronic test equipment
".
It is considered that the human body presents a non-inductive resistance of about 2 k
Ω.
Case with alternating current
For voltages greater than 25 V: A current of 3 mA (RMS)
Case with direct current
For voltages greater than 60 V: A current of 12 mA
In any case, the discharge energy must not exceed 350 mJ
NOTE
:
A peak current of 0.7 mA can be felt by some people even though it does not present a
risk.
