Determine the best method for connecting the power converter the power source and for routing the cable, taking into consideration the following principles.
 On electric fork lifts, connect the power as close to the battery as possible, but not directly from the battery terminals or before any main fuse.
 On gasoline, diesel or propane fork lifts, connect the power as close to the battery terminals as possible, avoid using existing wiring.
 Ensure that the fuse is as close as possible to the power source. The fuse must be securely mounted and in an accessible location.
The ideal location for connecting the converter power input cable would be an accessory output in your forklifts fuse panel. Be sure the circuit has a load capacity capable of
supporting the converter. Refer to the Forklift Owner’s Manual for identification of the circuit. If a fused output is not available, the converter must be installed with an in-line
fuse holder and UL Listed fuse as follows; 12V or 24V fork lift, use a 8A fast blow ceramic fuse, for a 36V-60V fork lift, use a 5A fast blow ceramic fuse.
WARNING! Shortening or modifying the cable(s) will void all warranties.
1. Disconnect the fork lift battery.
2. Connect the red wire to the fork lift's positive (fused) power source.
3. Connect the black wire to the fork lift's negative power source or chassis ground.
4. Connect the yellow wire to a switched power feed such as the ignition switch. B+ voltage must be present on the yellow wire for the unit to operate.
5. Ensure the wiring connections created are secure and sufficiently insulated from each other.
Printer Connection
1. Connect the small cable with the DC jack to the DC converter cable. Route the cable to the power
converter using the Cable Routing guidelines.
2. Re-check all connections. Reconnect the Forklift Battery
3. STOP! After completing the installation of the converter and electrical connections. Using a
voltage meter take voltage measurements before connecting the printer. Center pin is always
positive and should measure ~12 VDC. If ~12 VDC is not present or the voltage is out of range,
re-check all connections (see illustration above).
4. Connect the cable to the printer; the printer should now begin charging.
