CONNECTING

The Mastervolt Service Centers have all accessories
available, e.g. battery terminals and supply cables in
all sizes.
Before beginning to connect the wiring,
make the AC and DC distribution voltage-
free.
Opening the front panel
Remove the two Philips screws from the front panel
of the cabinet. Pull the grey front panel away from the
cabinet (downwards). The terminals and cable glands
are now accessible (see fig. 4).
3.4.1 Connecting AC wiring & earth wiring
General:
The inverter is protected against overload and short
circuit, so it is not necessary to install a fuse in the
output of the inverter.

IMPORTANT!

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.
Check whether the voltage from the inver-
ter is the same as the connected equip-
ment.
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.
To connect the MASS Sine inverters:
Switch the on/off/remote switch to 'OFF'. The L1, N
and PE terminals are situated on the left hand side
inside the cabinet.
EN / Mass Sine 12/1200, 12/2000, 24/1500, 24/2500 & 48/2500 / June 2000
Connect the AC on-board system brown phase 1.5-
2.5 mm 2 wire to terminal L1, the blue 0-phase wire to
terminal N and the green/yellow earth wire to
terminal PE (see fig. 4).
3.4.2 DC wiring
Keep the cable length as short as possible, this will
keep the system efficiency as high as possible. The
recommended minimum size of the battery cables is:
12/2000 &
24/2500
cable thickness 50 mm 2
The recommended length is a maximum of 6 meters.
When longer cables are required, use thicker cables.
When possible, use coloured (red and black) battery
cables. If this is not possible, mark the cables with
red and black isolation tape or heat shrink sleeve.
Battery cable connections
Pull the battery cables through the glands at the
bottom side of the inverter. Keep the cable con-
nection between batteries and inverter as short as
possible (maximum 6 meters). Connect the black ne-
gative battery cable to the negative connection bolt
(right) and the red positive battery cable to the
positive bolt (left) of the inverter. Cut the cables to the
right length and fix, if necessary, connect cable
clamps to both ends. Connect the negative cable to
the negative battery pole and the positive cable via
the inverter fuse to the positive red pole (see fig. 4).
Pull the battery cables through the glands
before you install the cable clamps.
