•
The transformer needed to power the system must comply with standard EN 60742
(dual isolation), or with equivalent isolation, e.g. VDE 0551.
!
•
The control unit must be protected with an external fuse, whose rated breaking current
must be 1 A.
)
•
The TEST/RESTART button must be located so that the operator can see the protected
area when restarting, testing or overriding.
)
•
The external illuminated indicator for muting override enabled must be located so that it
can be seen from all sides of operation.
)
•
Read the section on the muting function and its use before locating the sensors for the
activation of this function.
!
•
Check that the load does not absorb current in excess of 250 mA forr each OSSD; in
this case a protection device will intervene to limit the maximum current. If loads with
currents in excess of 250 mA for each OSSD or alternating current are to be controlled,
please connect an external safety relay module.
)
•
Muting input A and Muting input B can be provided by mechanical switch, photoelectric
sensors, proximities switch, with closed contact in the presence of the object to be
detected.

•
The test connection must always be executed with a N.C. button or connected to an
automatic device, such as a PLC.
