hubs. Also, the factory supplied hole plug
should be installed in the center port at the
rear of the E4000, and must be installed with
the step on the inside washer facing the hole
in the register base. This will center the hole
plug correctly and ensure it will not leak.
If the E4000 is equipped with a heated display,
the leads from the display heater will be
preinstalled at the 12 volt terminals. If the wires
are disconnected during the installation process,
reinstall the red display wire to terminal 24 and
white to terminal 23. The ferrule containing both
white and red wires attaches to terminal 16
(gure 4-18).
4.15 Wiring the Junction Box
The data/power cable should pass through the center port in the junction box. The printer power cable
should pass through the left port, and the truck power cable should pass through the right port. Factory
supplied cable strain relievers are required to prevent damage to cables as they enter the junction box.
Make the connections as shown in the wiring diagram (gure 4-19) for the junction box.
Terminal block J8 is specically for powering the RML2000. The red wire should be connected to the +19
VDC terminal of this block, and the red/black wire to common. Do not use the printer power terminals to
power the RML2000.
Always complete the HHC DATA wiring, even if you are not using a hand-held computer, because this
is also required to communicate with the register when using the E4000 conguration program. Note:
Terminal 5 of the HHC block and the SHIELD terminals on the HHC and POWER blocks are not used.
Connect the drain (shield) wire to the SHIELD terminal of the PRINTER DATA terminal block. The length
of the shield wire should be such that it cannot contact the metal junction box or lid.
Do not replace the E4000 cover or the junction box lid at this point.
