3.9 E-Multi Controller Safety Hazards
See also “Figure 3-2 E-Multi controller safety hazards” on page 3-14.
WARNING
-
ELECTRICAL SHOCK HAZARD
It is crucial to comply with these warnings to minimize any personal danger.
• Ensure that all energies are properly locked out in the controller and
molding machine before installation of the controller into the system.
• DO NOT enter the cabinet without rst ISOLATING the supplies OR
having a qualied person selecting the BYPASS SWITCH to ON, to gain
live access to the controller. There are unguarded terminals inside the
cabinet which may have a dangerous potential across them. Where a
three-phase supply is used, this potential may be up to 600VAC.
• With the BYPASS SWITCH set to OFF opening the high power section
of the controller will cause the circuit breaker to TRIP, disconnecting all
power to the cabinet.
• Voltage and amperage cables are connected to the controller and the
mold. There is also a voltage cable connection between the servo motor
and the controller. Electric power must be shut o and lockout / tagout
procedures followed prior to installing or removing any cables.
• Integration should be done by properly trained personnel based on local
codes and regulations. Electrical products may not be grounded when
removed from the assembled or normal operating condition.
• Do not mix electrical power cables with thermocouple extension
cables. They are not designed to carry the power load or list accurate
temperature readings in each other’s application.
WARNING
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 voids the warranty.
