Step 5 – Connect actuator power
The actuators connect to a 12VDC power source using the 3' (.9m) power harness
(CM20044) supplied with your kit. The source may be the engine battery terminals,
a battery switch, a panelboard, or a busbar. The combined length of the actuator and
power harness is 9' (2.7m), so the power source must be aft and within reach of the
harness. If you do not have a power source within reach, refer to section 5.5.1.
In operation each trim tab actuator will draw 10–15A, with momentary peaks up to
20A. Each actuator must be protected with a dedicated fuse or breaker. It is
important that power supply wires are correctly sized for the load according to
ABYC or ISO requirements.
WARNING!
Each trim tab actuator requires its own circuit protection device.
Use only fuses or circuit breakers designed for marine use.
WARNING!
Panelboards or busbars must be supplied with a conductor and circuit pro-
tection device appropriately sized for all loads that may be connected to it.
