External Sync
This non-isolated input can be used to synchronise the inverter output with an opportune signal coming from an
external source. If it is to be installed it is necessary to:
Use an isolation transformer with an isolated single-phase output (SELV) within the range 12÷24Vac with a
power ≥ 0.5VA
Connect the transformer secondary to the "EXTERNAL SYNC" terminal (see "Views of the TRI POWER X33
HE connections”) using a double isolation cable with a 1mm2 cross section. Warning: always respect the
polarisation as in the figure below:
Once the installation has been completed, the command has to be enabled by using the advanced configuration
software TRI POWER X33 HE Tools in the CD-ROM provided with the TRI POWER X33 HE.
Remote maintenance bypass connection
An additional maintenance bypass may be installed on a peripheral switchboard (see diagram below), for example, o
allow replacing the TRI POWER X33 HE without interrupting the power supply to the load.
Note : The Company provides this accessory already pre-assembled in an IP65 plastic box.
It is essential to connect the "SERVICE BYPASS" terminal (see "Views of the TRI POWER X33 HE
connections") to the auxiliary contact of the SERVICE BYPASS switch. The closure of the SERVICE
BYPASS switch will open this auxiliary contact which informs the TRI POWER X33 HE that the
maintenance bypass has been inserted. The absence of this connection may interrupt the power
supply to the load and damage the TRI POWER X33 HE.
Use cables with cross sections in compliance with the indications given in the "Cross section of the cables"
paragraph.
In order to connect the "SERVICE BYPASS" terminal to the auxiliary contact of the remote maintenance
bypass isolator, use 1mm2 double isolation cables.
If the TRI POWER X33 HE is connected to an isolation transformer, check the compatibility between the
“remote maintenance bypass” and the neutral regime of the installation.
