3.9 E-Drive Safety Hazards
WARNING - ELECTRIC SHOCK HAZARD
Most controller warnings pertain to electrical hazards. It is crucial to comply
with these warnings to minimize any personal danger.
•
DO NOT enter the cabinet without first ISOLATING the supplies. As a
three-phase supply is used, this potential may be 600 volts or higher.
• 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 off and
lockout / tagout procedures followed prior to installing or removing any
cables.
• The main power disconnect is a 20A breaker located at the connector
end of the cabinet. This main power switch is used to safely disconnect
the total load current at the time of switch on and switch off.
• The main power switch can be locked using a padlock applied under
the lockout / tagout procedure found in “3.6 Electrical Lockout” on page
• 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.
3.9.1 Operational Environment
WARNING
• The display console and controller cabinet together are designed for
use in the plastic injection molding industry as with Milacron and third
party servo gate control, commonly used in mold tools. They must not
be used in residential, commercial or light industrial environments.
They must not be used in an explosive atmosphere or where there is a
possibility of such an atmosphere.
• The controller cabinet and its touchscreen console should be installed
in a clean and dry environment where the ambient conditions do not
exceed the limits that follow:
• Temperature
+5 to +45°C
• Relative Humidity
90% (non-condensing)
• Do not make changes to the factory settings without the help of
Mold-
Masters
service personnel. Changes to these settings can result in
hazardous out-of-control or unexpected movement. It can also damage
the machine, and it will void the warranty.
