Maintenance 5-1 1999 Nordson CorporationAll rights reserved 107 962HIssued 11/99Manual 21-19Section 5MaintenanceWARNING: Allow only qualified personnel to perform thefollowing tasks. Follow the safety instructions in this documentand all other related documentation.WARNING: To prevent electrical shock that can causepersonal injury or death due to accidental discharge of paint orsolvent from the gun, perform the following tasks beforeperforming any maintenance procedures: Turn off the fluid and air supplies. Relieve fluid and air pressure in the system. Turn off the power supply. Ground the gun electrode.WARNING: If you remove the electrostatic cable duringmaintenance of the gun, refer to the Installation section forcorrect installation steps. If you incorrectly install the cable, or ifyou use electrostatic power systems or cables other than theEPS8 or the Nordson electrostatic cable, destruction ofproperty, electrocution, explosion, fire, or death can occur.WARNING: Early cable failure is usually due to the presence ofair in the cable/resistor bore, which allows the presence of acorona when applying electrostatic power. This corona causesrapid degradation of cable and gun components that can resultin a loss of operating safety by creating an ignition hazard.The electrostatic cable is the high-voltage link between the power supplyand the AN-8 Plus gun. Because the cable conducts high voltage, it issubject to electrical breakdown (burn-through or carbon tracking) if it isnot correctly maintained.1. Introduction2.
