INTERLOCKS
Interlocks required by code are as follows:
• Booth Fan Interlock - When the booth fan is on, a contact closure is made.
• Conveyor Interlock - when the conveyor is moving a contact closure is made.

Failure to connect interlocks could result in fire or explosion.

ALWAYS ensure that high voltage is OFF before cleaning the applicator with sol-
vent. NEVER clean the spray applicator with high voltage ON, as this is a severe
fire hazard and risk to personnel safety.
To install the control unit interlocks perform the following:
1. Turn the control unit off and remove the fuses.
2. Loosen the front panel screws and slide the control unit chassis out.
3. Using a small blade screwdriver, remove the factory installed test jumper from TB1-L2 to TB1-L3 (Figure 3).
4. Using a shielded cable for the interlock wiring (supplied by user), route through the interlock connector on the
rear of the control unit and terminate to TB1-L2 and TB1-L3. The shielded cable must have a minimum rating of
300V and 105°C and its conductors should be 0.8mm2 (18 AWG) minimum. Secure the cable to the interlock
connector so that the shield of the cable is connected to the chassis of the enclosure.
5. Slide the chassis back in, secure the front panel screws, and replace the fuses.
NOTE:
Some codes may require the interlock wiring to be run in conduit. In this case shielded cable is not necessary, but
the conductors used should still meet the ratings specified above.
The interlock contacts (supplied by user) should be rated for at least 1-amp at 240 volts AC.
