Installation:

The keypad and PME unit should be inspected for physical damage before installation.  Any cracked, broken or bent items on either unit should be reported to your shipping firm or to DNA for proper disposition.

Ensure all power is off by disconnecting the marine battery(s) from the boat system or de-energizing the battery switch.

Prepare the unit for installation by removing all packaging materials.  Keypads must be mounted to a flat surface using a properly positioned cut out for the 

keypad connector pigtail.  The keypad-mounting studs should be secured through the panel using 10-32 UNF nut and lock-washer.  Tighten the nuts to snug only.  Do not exceed torque ratings as this will crack or deform the keypad, which will cause intermittent operation.

Connect the keypad pigtail Deutsch connector to the wire harness.  Wire harnesses are not provided by DSS.  They must be designed, manufactured and installed to meet the DSS Pi series requirements as well as the specific design requirements of the application, for length, termination, wire size, etc.  It is Cruisers Yachts’ responsibility to ensure this was done to meet or exceed design specifications.

To mount the PME, the unit must be installed in a non-submerged, ventilated space as to meet the operational specifications listed in the product documentation.  Units that are not “IP” protected must not be mounted in an engine compartment.  The ambient temperature must not exceed 70 Degrees C.

Secure the PME with four, ¼ - 20 bolts, nuts and washers or equivalent wood screws (not provided).  Tighten to snug only.

Secure the negative power side terminal to the negative power lug and secure with the nut and washer provided.  Secure the positive power side terminal to the positive power lug and secure with the nut and washer provided.  Take care to never reverse the terminal connections or reverse the order of connection. Tighten power lugs to snug only.  Over-tightening will cause the lug to crack or fail.

Never connect the Deutsch 40 pin connector to the PME without connecting the power terminals first.

Important: to un-install the PME from the system, the steps to be taken should be the reverse of the installation sequence.  Never disconnect the power terminals while the Deutsch connector block is still attached.  Failure to disconnect the Deutsch connector block first may cause the PME to receive reverse current causing failure of the unit and voiding any warranties.

The system is now ready for power and operation.  Re-connect the main marine battery(s) to the circuit and follow the operational instructions below.
