• Treatment of grounding
wire terminal for unit
grounding wire and
battery grounding wire
onto the vehicle chassis.
• Rain water is prevented
from entering the van,
and the refrigerating
capacity is prevented
from dropping.
7. When wiring is made under the floor or
at a place where rain water splashes, set
up a trap on the straight line so as to
prevent water drop from entering the
connectors of connecting equipments.
8. Be sure to use the specified cables
(thickness and sheath) for wiring.
9. Use the compression terminal or solder
type terminal to connect the cable.
(Solder onto caulking section of crimp
terminal. Hand-twisting and tape
retaining alone are prohibited.)
10. Check the electrical wiring for
interference with any vibratory object
on the way.
11. Insert the connector with lock until it
makes "click" sound. Here, do not
tighten the connector lock with a flat.
12. When installing the connection harness
in the box later, securely seal the
through hole of the box.
13. When using the closed end type
connector outside the box, sufficiently
seal it with sealer.
1. The terminal area is clamped and sealer
coated to prevent the ground cable from
suffering of being internally broken
owing to vibration during car running.
2. Remove paint from the chassis side.
1. If any hole is produced on the van side
or any clearance is produced on the
passing-thru hole (unit mounting bolts,
refrigerant pipe, electric wiring, drain
hose, etc.) in the outfitting process, close
the hole or clearance by coating sealer.
7. Defective contact due to
generation of rust and
broken wire.
8. Unit may be subjected to
fire owing to heating or
sheath thermal damage
which is caused by
insufficient wire capacity.
9. Unit may be subjected to
fire owing to heating and
firing caused by increase
of the contact resistance.
10. Fire may happen on the
damaged sheath of
cable.
11. The connector may be
removed by vibration.
1. Many defects resulting in
burning of alternator,
relay, etc.
1. Rain water enters the van
through the thru-hole or
clearance, and the
thermal insulator is
moistened.
2. Thermal load enters
through the clearance of
the thermal insulator and
is moistened to cause
poor cooling.
7.
8. 9. Observe the electric
wiring standards.
(Neglection is
prohibited. It has been
reported that fire
actually happened
owing to the
neglection.)
10. Clamp cable securely.
Select the cable
connection area which
is free from oil or fuel
sticking.
1. Verify that the hole
clearance is wholly and
securely sealed.
