Protect the cables - The power transmission cables must be protected from mechanical damage
and fatigue. Run the cables through an approved conduit / trunking.
Cable strain relief - Prevent mechanical strain on all cables. Cable ties or cable glands are a good
way to prevent mechanical strain on the cables.
Fuses - The DL-300 controller should be protected with a suitably rated ‘slow-blow’ DC fuse or DC
circuit breaker. Please refer to the table below for the correct rating. The fuse or breaker should be
positioned between the DL-300 and batteries (on the positive cable)
