Final Steps & Post-Installation Checks
Before using the Commander P2 or P2VS for the first time, please verify that the entire
system & all its components are safely and securely mounted, and will not shake loose from
the vibrations that can be expected in a marine boat.
Electrical Checks
 Only after all these checks are passed should you plug the power plug into
the JI–BATTERY INPUT receptacle on the SPU.
1) Check the power supply wiring (from the battery/breaker).
• Verify that the polarity and voltage are correct (use an accurate voltmeter for this).
• Check for correct wire size, tightness of all connections, fusing, and proper operation
of the battery power breaker or switch.
2) Check the connections from the Compass(es) to the SPU.
3) Check the connections from the Rudder Follower Unit to the SPU.
4) Check that when the rudder is manually moved from full Starboard to full Port, and
vice-versa, the RFU moves completely freely, and is not being restricted in any way.
5) Check the connection(s) from the Control Head(s) to the SPU.
6) Check the connections to the drive equipment from the SPU.
7) Check that all cables are neatly placed and secured.
8) Ensure that extraneous materials (bits of insulation, wire pieces or strands, etc.) have
been removed.
During the first few weeks of operation, repeat the checks above at least once.
Completing the Wiring
1) Route all the wires and cables sideways out from the SPU (to the left &/or right, as
appropriate). Use external tie-downs or cable holders to keep the wires & cables secure,
with no excess strain on them, or on the plugs that are mated to the SPU’s receptacles.
Many potential problems can be avoided by ensuring that cabling and wiring do not
cause strain on the connectors!
2) If the SPU is mounted on a vertical surface, route all wires & cables downwards, within a
few centimetres of the edge of the SPU. If the SPU has been mounted on a horizontal
surface, form drip loops in all wires & cables, close outside the edges of the SPU.
3) Finally, carefully re-install the Wiring cover on the SPU. Be sure not to pinch any of the
wires or cables between the Wiring Cover and any other part of the SPU.
4) Secure the Wiring Cover with the two knurled thumb-nuts.
5) Ensure that the cabling and wiring to all system components, especially Remote
Controls , are well secured with clamps or alternative fasteners.
