3.8.1 Power supply fusing
A one-amp fuse should be connected in line with the battery positive terminal to the controller and
modules. These items should never be connected directly to the starting battery.
Fuse value and type depends on the number of connected devices and wire length.
The recommended fuse type (not fast) is T1A due to internal capacitors charging during
power up.
3.9 Voltage and current inputs
WARNING!
Risk of personal injury due to electric shock when manipulating voltage terminals under voltage! Be
sure the terminals are not under voltage before touching them.
WARNING!
Do not open the secondary circuit of current transformers when the primary circuit is closed!!! Open
the primary circuit first!
Use 1.5 mm
2
cables for voltage connection and 2.5 mm
2
for current transformers connection.
Adjust nominal voltage, nominal current, CT ratio and PT ratio by appropriate setpoints in the Basic
Settings group. Learn about how to view and change setpoints in the User interface chapter.
