HRSi Charge Regulator Installation and Operation
Doc No : SM-346 Issue B 24.04.08 Marlec Engineering Co Ltd
Easy Steps To Avoiding Damage To
The HRSi Charge Regulator
1. During installation or maintenance set the Stop position. See Fig 1 :-
2. Do not use the Stop switch to brake a speeding Windcharger.
3. During installation the first “live” connection must be to the battery.
This configures the 12V or 24V operation.
4. Never disconnect the HRSi from the battery unless the Stop switch is
activated and ensure reconnection is made before returning to the Run
position. Any on-board battery management systems must not break this
connection.
5. Never connect an open circuit running Windcharger to the HRSi as this
will cause permanent damage.
6. Never make the connection of a solar panel in direct sunlight to the HRSi .
7. Do not exceed the recommended 160W of solar panels.
8. Always fit an appropriate blocking diode to each solar panel input.
9. Never connect the HRSi to the battery or any charge sources in reverse polarity.
10. Avoid exceeding the recommended wiring distance between HRSi and battery. Longer distances
require heavier gauge cable or charging efficacy will be affected.
11. Never obstruct the ventilation slots of the HRSi.
12. Note that in high levels of auxiliary charge, eg from an engine, the HRSi may enter regulating
mode and thus the windcharger will run at a slow speed.
Please take note of these steps to avoid the loss of warranty cover.
