2.4.3 Cabling and Wiring
All wire shall be selected in accordance with the original aircraft manufacturer's Maintenance Instructions
or AC43.13-1B Change 1, Paragraphs 11-76 through 11-78. Unshielded wire types shall qualify to
MIL-W-22759 as specified in AC43.13-1B Change 1, Paragraphs 11-85, 11-86, and listed in Table 11-11.
For shielded wire applications, use Tefzel MIL-C-27500 shielded wire with solder sleeves (for shield
terminations) to make the most compact and easily terminated interconnect. Follow the connector map in
Section 2.7 as required.
Allow 3" from the end of the shielded wiring to the shield termination to allow the connector hood to be
easily installed. Reference the interconnect drawing in Section 2.7 for shield termination details. Note that
the hood is a "clamshell" hood, and is installed after the wiring is complete. Aircraft harnessing shall
permit the unit to be removed from the panel for easy access to all side adjustments. Do NOT mount the
unit until all adjustments have been performed.
Maintain wire segregation and route wiring in accordance with the original aircraft manufacturers
Maintenance Instructions.
Unless otherwise noted, all wiring shall be a minimum of 22 AWG, except power and ground lines, which
shall be a minimum of 20 AWG. Reference the Interconnect drawing for additional specifications. Check
that the ground connection is clean and well secured, and that it shares no path with any electrically noisy
aircraft accessories such as blowers, turn and bank instruments or similar loads. Power to this unit must
be supplied from a separate circuit breaker or fuse (fast blow), and not attached to any other circuit
breaker without additional protection. Verify that the selected circuit breaker size and wire gauge are
adequate for the installation using the techniques specified in AC43.13-1B Change 1, Paragraphs 11-47
through 11-51 and 11-66 through 11-69.
2.4.4 Tie Lines
2.4.4.1 N335-001/-002
When no other unit is to be connected to the tie-line, set the ICS TIE ADJUST switch to the '1 NAT LOAD'
position (position 1), and connect a 1.8 k
:
resistor between the ICS TIE HI and ICS TIE LO lines (refer to
the appropriate drawings listed in section 2.7).
2.4.4.2 N335-201/-202
When no other units are to be connected to the tie-line, set the SUPER TIE SELECT switch to the 'NAT
TIE' position (position 0), set the NAT TIE SELECT switch to the '2 NAT LOADS' position (position 1), and
connect a 910
:
resistor between the ICS TIE HI and ICS TIE LO lines (refer to the appropriate drawings
listed in section 2.7).
2.4.5 Mechanical Mounting
The N335 can be mounted vertically or horizontally in standard Dzus rails.
Before the unit is mounted, make all functional tests, and trimpot adjustments. Be sure the harness has
enough clearance to permit the unit to be pulled out for re-adjustment, if needed later. Make sure unit is
securely fastened to the Dzus rail, and that the connector locks are tightened before any flight is
attempted.
