clearance between the equipment and other objects.
Install lockable power disconnects to isolate the equipment and all
independently powered auxiliary devices from their power sources.
Properly ground all equipment. Contact your local building code
enforcement agency for specific requirements.
Ensure that fuses of the correct type and rating are installed in fused
equipment.
Contact the authority having jurisdiction to determine the requirement for
installation permits or inspections.
Operating Practices
Familiarize yourself with the location and operation of all safety devices
and indicators.
Confirm that the equipment, including all safety devices (guards,
interlocks, etc.), is in good working order and that the required
environmental conditions exist.
Use the personal protective equipment (PPE) specified for each task.

Equipment Shutdown
To safely complete many of the procedures described in this document, the
equipment must first be shut down. The level of shut down required varies by
the type of equipment in use and the procedure being completed.
If required, shut down instructions are specified at the start of the procedure.
The levels of shut down are:
Relieving System Hydraulic Pressure
Completely relieve system hydraulic pressure before breaking any hydraulic
connection or seal. Refer to the melter‐specific product manual for
instructions on relieving system hydraulic pressure.
De‐energizing the System
Isolate the system (melter, hoses, applicators, 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 Applicators
NOTE: Adhesive dispensing applicators are referred to as “guns” in some
previous publications.
All electrical or mechanical devices that provide an activation signal to the
applicators, applicator solenoid valve(s), or the melter pump must be
disabled before work can be performed on or around an applicator that is
connected to a pressurized system.
1. Turn off or disconnect the applicator triggering device (pattern controller,
timer, PLC, etc.).
2. Disconnect the input signal wiring to the applicator solenoid valve(s).
3. Reduce the air pressure to the applicator solenoid valve(s) to zero; then
relieve the residual air pressure between the regulator and the applicator.
