Table 13-1 E-Drive Safety Hazards
Hazard Area Potential Hazards
Mechanical Hazards
Entanglement Hazard Do not operate the equipment with unconned long hair, loose clothing or
jewellry, including name badges, neckties, etc. These may get caught by
the moving belt mechanism and can cause death or serious injury.

During Maintenance
Always cover belt area with proper protecting sheet before any bench test
or in-mold testing.
Electrical Hazard Never touch or inspect the timing belt when power is on and E-Drive
motor and controller are connected.
Unplug the controller before any maintenance.
High Voltage and amperage cables are connected to E-Drive controller
(400VAC). Also there is high voltage cable connection between servo
motor and controller.
Heaters, servo motors and electrical components in the controllers could
come in contact with a person.
Always disconnect and use proper lock out procedures before performing
any maintenance work.
Trip Hazard Controller cables are a tripping hazard on the oor between the controller
and the mold.
Combination Hazards
Failure / Disorder of
Control System
Mixed-up connections of the motor power cables on dual motor units may
result in an out-of-control or unexpected movement causing damage to
the machine and a possible hazard should the machine fail.
Do not swap E-Drive controllers for di󰀨erent E-Drive systems without
checking manual as controller setup must match mechanical system as it
may result in an out-of-control or unexpected movement causing damage
to the machine and a possible hazard should the machine fail.
CAUTION
Make sure the controller power supply is unplugged or turned o󰀨 before
plugging in the cables of the motor. Otherwise it can cause damage to the
motor. Do not “hot-plug” the motor.
Carefully read the instructions before operating the equipment. If in doubt,
contact Mold-Masters for clarication.
E-Drive components are rated to operate at temperatures less than
40 ºC (104ºF). Do not heat the Hot Runner system without connecting a
proper cooling system.
In addition, if your application mold temperature needs to be set above
40 ºC (104 ºF). Use proper mold design for higher temperatures.
