1.3.3 Connecting the Load
Negative grounded Positive grounded
Open the cover at the load terminals. Connect
the wires leading to the load with the correct
polarity. Respect the appropriate wiring for
negative and positive grounded systems!
Wire size: See "Table of recommended wiring
for MPS units" on page 3.
Close the wire cover.
1.3.4 Connecting the Battery
Respect that batteries store a substantial amount of energy which can produce high current
and electric arc when a short circuit is applied to the battery. It is recommended to install a
battery fuse which must be able to carry currents of 1.5 times of your nominal system current
for safety considerations. Insert the fuse after you have connected all wires including the load
and make sure that all terminals are fixed tightly with proper polarity.
Negative grounded Positive grounded
Open the cover on the battery terminal side.
Connect the wires leading to the battery with
the proper polarity.
Mind the recommended wire length (See "Table
of recommended wiring for MPS units" on page
3). MPS terminals can connect up to 35 mm
2
wire (AWG#2).
Wire size: See "Table of recommended wiring
for MPS units" on page 3.
Close the wire cover.
1.4 Starting up the Controller
After double-checking all wires and terminals insert battery fuse.
1.4.1 Self test
As soon as battery voltage is applied to MPS, the unit begins a self test routine and wiring-
check. If system passes wiring-check, the LED display changes to "normal operation".
