Connecting
The Mastervolt Service Centres have all accessories available, e.g.
battery terminals and supply cables in all sizes.
Refer to the installation drawings during installation (chapter 8)
WARNING!
Before beginning to connect the wiring, make the AC and
DC distribution voltage-free.
4.4.1
Opening the front panel
Loosen the two Philips screws that secure the front cover plate for two
turns. Pull the grey front panel away from the cabinet (downwards).
The terminals and cable glands are now accessible.
4.4.2
Connecting AC wiring & earth wiring
The inverter is protected against overload and short circuit, so it is not
necessary to install a fuse in the output of the inverter.
CAUTION!
For safe installation it is necessary to:
•
connect the earth (PE) and neutral (N) of the inverter output to the
central ground;
•
insert a RCCB (earth leakage) switch of 30mA in the inverter output.
Please acquaint yourself with the local regulations on this issue!
WARNING!
Check whether the voltage from the inverter is the same
as the connected equipment.
WARNING!
The earth wire offers protection only if the inverter cabinet
is connected to the earth. Connect the inverter's earth terminal (at the
right hand side of the AC terminal block) to the hull or chassis via the
earth stud.
To connect the Mass SINE inverter to the mains:
1.
Switch the on/off/remote switch to 'off'. The L1, N and PE terminals
are situated on the left hand side inside the cabinet.
2.
Connect the AC on-board system brown phase 4mm
/AWG 11 wire
to terminal L1, the blue neutral wire to terminal N and the
green/yellow earth wire to terminal PE.
