External Connections - Ransburg 9040 Service Manual

9040 Low Voltage Control Unit Kit- Installation
9040 units shipped from the factory for
>
115 VAC input will have a 72771-06, 1 amp
front panel fuse installed. While 9040 units
shipped from the factory for 230 VAC input
will have a 72771-01, 0.5 amp front panel
fuse installed. If the other input is required,
it is recommended that the fuse be
changed in order to keep the same level of
protection. Both fuses are shipped with
9040 control units.
EXTERNAL
CONNECTIONS
When connecting external wires to the
>
9040 Cascade control unit, some of the
wires will be connected to the External
Wiring Plug 2PL and some routed through
the External Wiring Grommet. When wiring
through the External Wiring Grommet,
leave enough slack in the wires so that the
9040 control unit chassis can still be slid
out of its enclosure if required. For
installations requiring conduit, route all
wires through the external wiring grommet
opening and connect to the existing wires
on the inside of External Wiring Plug 2PL
(2SOF) when necessary.
Low Voltage Cable Connection
Connect the low voltage cable from the side of
the external cascade to the Low Voltage Cable
Socket located on the back of the control unit.
Hand tighten only.
High Voltage Cable Connection
Connect the high voltage cable by securing the
grounded end of the cable into the external
cascade then securing the other end to the
applicator.

Ground Connections
Crimp the appropriate connector onto the
Ground Wire Assembly and install from the
control unit ground stud, located on the back of
the control unit to a true earth ground.
Again crimp the appropriate connector on to the
cascade Ground Wire
Ground Wire Assembly from the external
cascade lug to a separate true earth ground.

> The Ground Wire Assembly MUST
be connected from the power supply
ground stud to a true earth ground.
Supplemental ground is provided via the
ground stud to the enclosure, through the
front panel screws, and to the chassis
module. Therefore, ensure the front panel
screws in the 9040 Cascade control unit
module are securely fas-tened to the rack
enclosure during operation. If it becomes
necessary to slide the chassis out for
testing purpos-es, connect a ground wire
from the enclosure to the chassis.
Interlocks
! W A R N I N G
> ALWAYS ensure that high voltage is OFF
before flushing the spray applicator with
solvent. NEVER flush the spray applicator
with high voltage ON, as this is a severe fire
hazard and risk to personnel safety. It is
recommended that the high voltage control
be interlocked with the solvent flush signal
so that high voltage is automatically locked
out whenever flushing occurs. Consult your
authorized Ransburg representative for
information on interlocking the high voltage
OFF signal with the solvent flush signal.
