GBK51948 RHINO2
Installation Manual Issue 5
The torque settings for the DS160 and DS180 battery terminal’s screws should be between 4.5Nm and 5.5Nm.
For DS90 and DS120 units, it is essential that at least four (2 pairs) battery terminals are used.
Note
A thermal circuit breaker or fuse must be installed between the battery supply and the controller, to protect
both the batteries and the system wiring. This shall be mounted as close as possible to the battery terminals as
per ISO7176-14 requirements. The thermal circuit breaker should have a trip rating no higher than the current
limit of the controller or the protection wire. Check thoroughly to ensure that it provides the necessary degree of
motor protection.
Model Fuse rating Circuit breaker rating
DS90 75A 60A
DS120 85A 70A
DS160 100A 80A
DS180 110A 100A
Note
The thermal circuit breaker and fuse ratings, shown above, are for guidance only. The correct rating depends on
your system (modules and cables) and should be calculated and verified through design and testing. Ensure
that all wiring, overload selection and positioning complies with ISO7176-14 requirements.
If the two batteries are permanently wired together (for example in a single battery box),
the best position for the circuit breaker is between the two batteries. If the batteries are
separated (individual battery boxes), each battery requires a circuit breaker or fuse. A slow-
acting, thermal type circuit breaker is suggested. Make sure that the protection system is in
compliance with ISO7176-14 requirements.
