IMPORTANT INSTALLATION NOTICE:
For IRIS models manufactured after February 2017,
the AM II charger connector harness (Ref. 2) and
charger (Ref. 12) are the only kit parts required for this
upgrade. The new kit AM II charger connector
harness (Ref. 2) easily installs in the same location as
the original red battery connector wire assembly. The
machine’s existing telemetry harness is pre-equipped
with an open connector to accept the new charger
connector harness. Carefully follow the kit installation
instructions with this in mind.
When installing the complete IRIS kit with the
addition of the AMII upgrade kit, two telemetry
harnesses (Ref. 1) will be provided. One from each
kit. Only one harness is required for both kits.
PREPARE MACHINE FOR KIT INSTALL:
1. Park machine on level surface, turn off machine,
remove key, and set parking brake if equipped.
2. Disconnect battery cable from machine.
WARNING: Always disconnect battery cables
from machine before working on electrical
components.
3. Remove seat, battery compartment shroud and
the front two batteries from machine.

4. Remove the charger connector interlock switch
from machine and discard. Save backing plate for
reuse.

6. Remove the existing telemetry harness from
machine and discard. Do not remove any other
parts associated with telemetry system.
NOTE: For IRIS models manufactured after
February 2017, the removal of the existing telemetry
harness is not required. The existing telemetry
harness is AM II kit compatible. To confirm, the
harness includes an open AM II charger connector
as shown below.

telemetry system during install, remove the in-line
fuse from the new telemetry harness. Do not
misplace fuse.
10. Install the new telemetry harness. Follow the
same routing path as old harness. Connect the
new telemetry harness to the following
components. Secure harness with cable-ties.

11. Carefully cut a hole into the battery shroud as
described.
12. Reinstall the batteries, battery compartment
shroud and seat. Reconnect battery cables.
13. Reinstall fuse into telemetry harness.
TEST KIT FOR PROPER OPERATION:
1. Plug the new charger into the telemetry battery
charge connector.
2. Use existing AC power cord from old charger
and plug new charger into power outlet. Wait up
to 30 seconds for charger to start. A yellow
lightning bolt will illuminate on the charger to
confirm the batteries are in the charge cycle.

charger
3. Turn key on to confirm the charger interlock
switch disables the machine during the charge
cycle. An audio alarm (horn) will beep nine times
repeatedly indicating that the charger is plugged
into machine which also disables the machine. If
the alarm fails to beep, check the interlock
switch for proper installation. Check wire
connections and roller alignment. Repeat
step.
4. After testing is confirmed, contact the Tennant
technical service department as instructed
below.

CHARGER PROFILE SETTING:
IMPORTANT: To properly report battery charging
data via IRIS, contact Tennant technical service
department to set the charging profile to your
specific battery type. Please have battery type
information available when contacting service.
IRIS TELEMETRY KIT ACTIVATION:
If the complete IRIS telemetry system was installed
with the addition of the AM II upgrade kit, call the
Tennant technical service department to activate the
IRIS module and to set the charging profile. The
IRIS telemetry system must be activated to
complete the install. Please have machine serial
number and IRIS module SIM number available
when calling for activation.
NOTE: When batteries reach end of life and must
be replaced, Tennant highly recommends that the
same battery type be used to continue to maximize
the machine performance. In the event a battery
with a different amp hour (AH), type (flooded, AGM,
Gel), or manufacturer is selected for replacement
please contact Tennant technical support
department for assistance in determining the
feasibility of the replacement batteries and selecting
the correct charging profile.
