4.8 MBSDU Panel
1. Connect signal cables between MBSDU panel, STS and inverter shelves as shown:
2. Remove the shorting plug on CN1 and connect the 4-pin MBS cable to the CN1
connector on the backplane of the STS shelf.
3. Connect the 5 bus bars supplied with the MBSDU panel to the STS
backplane via the corresponding connectors of MBSDU panel as shown:
DANGER
To meet CEC/NEC requirements – to prevent fire, electric shock, improper operation of circuit
protection devices, as well as improper operation of the equipment – an electrical bond between
neutral and ground is required at the AC source or distribution point of an inverter system.
Ensure that the installation complies with the specific wiring rules applicable to your country or
area of jurisdiction.
For INEX systems with a MBSDU, this can be facilitated by
installing a wire jumper between Neutral and Ground on the
terminal block labelled “output” on the back of the MBSDU
shown here:
4. Connect AC input to the terminal on the back left of
MBSDU panel according to the position of the labels as
shown.
5. Connect AC output to the terminal (according to the
label) on the back right of MBSDU panel to external
distribution or load.
#1, #1, #2
#3 (STS O/P)
#4 (AC I/P)
Wire jumper should be sized
for the maximum capacity of
the system. Refer to Table A.
