Input Power and Connection Requirements
Datamax-O’Neil MF8i Installation Guide
3 If a molded DC plug cable is purchased to connect to the printer, limit its length to 12
inches, due to voltage drops.
Printer Input Power and Connection Requirements
There are four ways to connect the MF8i to vehicle power — fuse box power cable, existing
power harness installations, cigarette lighter adapter, and battery.
Fuse Box Power Cable
(part # 220210-100)
To properly install the fuse box power cable, review the MF8i Truck Mount Extension Cable
Instruction Sheet (part # 110128-xxx) supplied with this cable.
Alternate Cabling
If you are installing your own cable, please review the following requirements and guidelines
for connecting to the MF8i 270 printer.
Power Cable Requirements
1 Use a minimum 16 AWG wire size — no exceptions!
2 All power to the MF8i printer must be fused. Either connect to the fuse box or install
an inline fuse.
(2a) Fuse box connection — the fuse rating minimum in the fuse box is 10 amps
(2b) Inline fuse — for an inline fuse, the fuse rating should be a minimum 7 amps
and installed within three feet of the printer connection
3 Always connect a ground strap as close to the printer connection as possible. The
ground strap must connect to the vehicle frame (paint scraping may be required). To
ensure the ground is connected properly, validate the connection to the frame using a
power meter.
Power Cable Guidelines
• Do not install cables or connections near wet areas.
• Do not install cables near, or around, sharp edges.
• Do not install wire with a smaller gauge than recommended.
• Install a fuse as recommended and at the rating indicated.
Note: Datamax-O’Neil accepts no liability for improperly installed cabling.
