Electrical Service & Supply
The Pelletizer requires a three-phase power supply. The power source must be grounded:
y For machines in the US: use a Solidly Grounded WYE Source.
y For machines outside US: use a TN-S grounding acc. to IEC 60364.
y All phases must be balanced, and voltages must be within ±10%.
The customer is responsible for the electrical installation of the pelletizer. This includes the
power cable and main circuit breaker which meet the specications below. The main circuit
must be suitable for proper lock out / tag out in accordance with international and national
standards and requirements.
Before startup, verify the direction of rotation is the same as indicated on the motor for the
hydraulic pump and on the motor for the oil cooler pump, if applicable.
