NOTES ON CONNECTIONS
x
The transformer needed to power the system must comply with
standard EN 60742 (dual isolation), or with equivalent isolation,
e.g. VDE 0551.
x
The control unit must be protected with an external fuse, whose
rated breaking current must be 1A.
x
The TEST/RESTART button must be located so that the
operator can see the protected area when restarting
,
testing or
overriding.
x
The external illuminated indicator for
muting override
enabled
must be located so that it can be seen from all sides of
operation.
x
Read the section on the
muting
function and its use before
locating the sensors for the activation of this function.
x
Check that the load does not absorb current in excess of 500
mA; in this case a protection device will intervene to limit the
maximum current. If loads with currents in excess of 500mA
and up to 6A alternating current are to be controlled, the
TGR-
SB
relay module must be connected to the outputs as shown
below.
The test connection must always be executed with a N.C. button or
connected to an automatic device, such as a PLC.
