3.6 Lockout Safety
WARNING
DO NOT enter the cabinet without rst ISOLATING the supplies.
High voltage and amperage cables are connected to the controller and
the mold. There is also a high voltage cable connection between the servo
motor and the controller. Electrical power must be shut o and lockout /
tagout procedures followed prior to installing or removing any cables.
Use lockout / tagout to prevent operation during maintenance.
All maintenance should be performed by properly trained personnel based
on local laws and regulation. Electrical products may not be grounded when
removed from the assembled or normal operating condition.
Ensure proper grounding of all electrical components before performing any
maintenance to avoid potential risk of electrical shock.
Often power sources are inadvertently turned on or valves are opened
mistakenly before maintenance work is completed, resulting in serious
injuries and fatalities. Therefore, it is important to ensure that all energies
are properly locked out and that they remain locked out until the work is
completed.
If a lockout is not performed, uncontrolled energies could cause:
• Electrocution from contact with live circuits
• Cuts, bruises, crushing, amputations or death, resulting from
entanglement with belts, chains, conveyors, rollers, shafts, impellers
• Burns from contact with hot parts, materials or equipment such as
furnaces
• Fires and explosions
• Chemical exposures from gases or liquids released from pipelines
