As outlined in NFPA 33 and OSHA standard
1910, the AC power line must be series inter-
locked with both the exhaust fan and conveyor.
To interlock the 9040 Classic power supply with
the exhaust fan and conveyor perform the fol-
lowing:
1. Ensure the front panel fuse is removed,
the power supply is unplugged, and the
ON/OFF switch is in the OFF position.
2. Open the power supply cabinet door.
! ALWAYS ALWAYS ALWAYS ALWAYS ALWAYS ensure that high voltage is
OFF OFF OFF OFF OFF before flushing the spray gun with
solvent. NEVER
NEVER NEVER NEVER NEVER flush the spray gun with
high voltage ON ON ON ON 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
OFF OFF OFF OFF signal with the solvent flush
signal.

A set of external relay contacts for High Voltage
(K1) and overload (K2) conditions is provided at
6PL-5, -6, & -7. See Figure 10 in the "Mainte-
nance" section of this manual for exact wiring
locations. These relay contacts are sometimes
useful in configuring the control of the spray gun
system.

If a method of high voltage triggering, other than
the factory supplied method, is required, the 9040
Classic Power Supply allows for external high
voltage control from a PLC, pressure switch, air
flow switch, or other user supplied device. To turn
the high voltage on, the user supplied device must
create a contact closure between terminals 6 and
7 of terminal block one (1TB). To connect the user
supplied, external high voltage control device,
perform the following:
1. Ensure the front panel fuse is removed,
the power supply is unplugged, and the
ON/OFF switch is in the OFF position.
2. Open the power supply cabinet door.
3. Route the contact wires of the control
device through the external wiring grom-
met and connect to the existing wiring
for 1TB-6 and 1TB-7. The control de-
vice contacts must be rated for at least
100 milliamps at 15 volts DC.
4. Secure the cabinet door, replace the
fuse, and plug in the power supply.
