This symbol is used to indicate presence
of hazards that can cause minor
personal injury or property damage.
CAUTION
Installation Instructions
Improper installation of alternator in an
explosive environment can cause severe
personal injury, death, or substantial
property damage. Alternator must be
installed by a qualified person trained in
the installation of alternators in explosive
atmospheres. For CSA and UL classifica-
tions and atmospheric conditions, see
page 2 of these instructions.
WARNING
Explosion hazard—substitution of compo-
nents may impair suitability for Class I,
Division 2.
Risque d’explosion—la substitution de
composants peut rendre ce matériel
inacceptable pour les emplacements
de Classe I, Division 2.
WARNING
Explosion hazard—do not replace any
component unless power has been
switched off or the area is known to be
non-hazardous.
Risque d’explosion—couper le courant
ou s’assurer que l’emplacement est
désigné non dangereux avant de
replacer le composants.
WARNING
Explosion hazard—do not disconnect
equipment unless power has been
switched off or area is known to be
non-hazardous.
Risque d’explosion—avant de décon-
necter l’equipement, couper le courant
ou s’assurer que l’emplacement est
désigné non dangereux.

ADVERTISSEMENT
ADVERTISSEMENT
ADVERTISSEMENT
This alternator contains no serviceable
parts except pulley, fan, and regulator.
Manufacturer’s hazardous location
certification is void if repaired except for
the pulley, fan, and regulator which may
be replaced with factory parts.
WARNING
ATTENTION
1. Mount alternator on a suitable bracket and
secure with hardware per alternator drawing
on page 2 of these instructions.
2. Remove anti-drive end (ADE) cover from the
alternator.
3. One of the following two alternator circuits
described below is required to operate alternator.
a. If alternator is to be self-energized, be sure
the link is connected between B+ stud and
IGN terminal (as shipped). This alternator
relies on residual magnetism to operate.
Observe all applicable safety procedures when
performing the following operation: If neces-
sary, restore lost magnetism by connecting
test light between B+ stud and R terminal for
1-3 seconds while alternator shaft IS NOT
TURNING and battery is connected to illumi-
nate test light. Check for magnetic field at
pulley. If magnetized, remove test light, start
alternator, and test.
b. If the alternator is to be energized through
ignition key, connect energizing signal lead
directly to IGN terminal and remove link
between B+ stud and IGN terminal. Torque
IGN terminal bolt to 2 Nm/18 lb. in. This
alternator relies on residual magnetism to
operate. Ensure battery voltage is present at
IGN terminal. Observe all applicable safety
procedures when performing the following
operation: If necessary, restore lost magnetism
by connecting test light between B+ stud and
R terminal for 1-3 seconds while alternator
shaft IS NOT TURNING and battery is con-
nected to illuminate test light. Check for
magnetic field at pulley. If magnetized, remove
test light, start alternator, and test.
4. Connect B+ cable to B+ stud on alternator. See
wire chart on page 3 for correct cable size and
length. Torque terminal nut to 9 Nm/80 lb. in.
5. Connect R lead to R terminal on alternator if re-
quired for vehicle operation (optional connection).
Torque R terminal bolt to 2 Nm/18 lb. in.
6. Connect B– cable to B– terminal stud on alternator
(B– is an isolated ground). B– cable gauge should be
same as gauge of battery positive
cable. Torque terminal nut to 9 Nm/80 lb. in.
Supply wires suitable for rated
load at 90°C ambient shall not
exceed 200°C.
Utiliser des câbles d’alimentation
appropriée pour 200ºC.
7. Perform a final inspection on the installation.
8. Re-install anti-drive end cover on alternator. Posi-
tion louvers consistent with deflection of rain or flu-
ids during normal operating conditions. Fasten
with screws and washers in four places. Use a suit-
able adhesive such as Loctite® 222. Follow manu-
facturer’s instructions. Torque screws to 3.4 Nm/30
lb. in.
9. Install suitable alternator drive belt.
10. Start engine. Confirm operation of charging
system meets specification.
