De-energizing the System

Isolate the system (melter, hoses, guns, and optional devices) from all power sources

before accessing any unprotected high-voltage wiring or connection point.

1. Turn off the equipment and all auxiliary devices connected to the equipment (system).

2. To prevent the equipment from being accidentally energized, lock and tag the disconnect

switch(es) or circuit breaker(s) that provide input electrical power to the equipment and

optional devices.

NOTE: Government regulations and industry standards dictate specific requirements

for the isolation of hazardous energy sources. Refer to the appropriate regulation or

standard.

Disabling the Guns

All electrical or mechanical devices that provide an activation signal to the guns, gun

solenoid valve(s), or the melter pump must be disabled before work can be performed on or

around a gun that is connected to a pressurized system.

1. Turn off or disconnect the gun triggering device (pattern controller, timer, PLC, etc.).

2. Disconnect the input signal wiring to the gun solenoid valve(s).

3. Reduce the air pressure to the gun solenoid valve(s) to zero; then relieve the residual air

pressure between the regulator and the gun.
