6. INSTALLATION CHECKLISTS
Junction Box
___ Mount the Junction Box in cab oriented so that the two RS232 ports are easily accessible,
and Jbox cover can be easily removed to access terminal connections.
___ Route power/data cable thru center port, printer power cable thru left port (RS232
connector side), and truck power cable thru right port.
___ Tighten three plastic cable glands to prevent pulling cables from JBox.
___ Check wire color connections as shown in the wiring diagram and tighten all terminal connections.
___ Connect the shield wire to the REGISTER PRINTER DATA terminal connection.
**Do not allow the bare shield wire to contact the metal junction box.**
___ Attach “TRUCK POWER +12 VDC” to a switched accessory circuit on the truck fuse
panel, using a 16 AWG cable with an in-line 5 amp fuse.
___ Attach TRUCK POWER COMMON to the negative terminal of the battery, using a 16 AWG cable, and
verify that the resistance from the terminal connection to the negative terminal of the battery is less
than 1 ohm (measured with power to the E4000 system switched off).
___ Attach TRUCK FRAME connection as a separate wire (not same wire as TRUCK
POWER COMMON) to the negative terminal of the battery, using a 16 AWG cable, and verify that
the resistance from the terminal connection to the negative terminal of the battery is less than 1 ohm
(measured with power to the E4000 system switched off).
Register
___ Attach to meter and tighten all connections (Section 4.5)
___ Install and wire RTD, if equipped (Sections 4.6 & 4.7, LPG).
___ Install rubber gaskets on the plastic cable gland and metal liquid tight connector so that the gaskets
are positioned on the outside of the register.
___ Route power/data cable thru right side port at rear of register (looking from the rear), and tighten the
plastic cable gland to compress the rubber gasket.
___ Route valve cable (if equipped with valve) thru the left side port (nameplate side), and tighten the
metal liquid tight connector to compress the rubber gasket.
___ Check the hole plug in the center port for correct installation and tighten.
___ Cut and remove the shield wire from the power/data cable to within 1 inch of where the cable enters
the register base. **Cut the shield wire on the register end of the cable only, not on the Jbox end**.
____Route the wires for the HHC and PRINTER around the left side (from front of register) and connect to
the terminal strip on top of register (See Figure 4-13).
___ Route the appropriate wires across to the right side of the register and connect to the terminal strip on
the side.
___ Check wire color connections (See Figure 4-13) and tighten all connections.
___ Check the voltage across terminals 23 and 24 and verify it is 12-14 VDC.
___ Check to be sure the display ribbon cable connectors are attached securely.
Printer
___ Set DIP switches all to OFF (See Figure 4-20).
___ Install printer ribbon.
___ Mount the printer in the cab.
___ Plug the printer power connector into the round DC24V port on back of printer.
___ Plug the 9-pin connector on the printer data cable plug into the RS-232 socket on the rear of the
printer.
