Installation Instructions
Improper installation of alternator in an
WARNING
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.
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
TUR NING 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 required 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.
