Connections of the model with separate bypass
The very first connection to be carried out is that of the protection conductor (earth cable), which
must be connected to the terminal marked PE. The TRI POWER X33 HE must not operate without
being connected to an earthing system
THE INPUT AND THE BYPASS NEUTRALS MUST ALWAYS BE CONNECTED.
THE INPUT AND BYPASS LINES MUST REFER TO THE SAME NEUTRAL POTENTIAL. DO NOT
CONNECT THE OUTPUT NEUTRAL TO THE INPUT OR BYPASS NEUTRAL.
Connect the input and output cables to the terminal board as shown in the figure below:
Note 1
:
The protection conductor (earth cable) connection must be carried out through eyelet terminal stud M6
Note 2:
Connections to the BATTERY module are required only when the optional Battery Box is present
R.E.P.O.
This isolated input is used to turn off the TRI POWER X33 HE remotely in case of emergency.
This TRI POWER X33 HE is provided from th
e factory with “Remote Emergency Power Off” (R.E.P.O.) terminals
short-circuited (
see "Views of the TRI POWER X33 HE connections"
).
If it is to be installed, remove the short-
circuit and connect to the normally closed contact of the stopping device by using a cable that ensures a double
isolation connection.
In case of emergency, the R.E.P.O.control is opened by activating the stopping device; the TRI POWER X33 HE
enters stand- by mode (see "USE" section) and powers off the load completely.
The R.E.P.O circuit is self-powered with SELV type circuits. Therefore, no external power supply voltage is required.
When closed (normal condition) a maximum current is present.
