3-5 Electrical
Considerations
!!! DANGER !!!
Improper electrical connections can damage the granulator and CAUSE SERIOUS
OPERATOR INJURY OR DEATH!
EX Series Screenless Granulators are designed for three-phase
voltage operation. Refer to the unit nameplate or ID plate for
proper voltage and amperage requirements.
NOTE: Make sure to provide a correctly-sized and protected supply of
electrical power to the unit.
Maintain a safe ground and disconnect the power supply before
servicing the unit. A qualified electrician should make electrical
connections, and disconnect and lock out electrical power
following OHSA 29CFR 1910.147.
Check serial tag voltage/amperage requirements and make sure
your electrical service conforms before making any electrical
connections. Full load amps for EX Series Granulators are listed
on the nameplate or ID plate. Make sure that all three phases are
wired correctly.
Bring properly sized power leads and grounds from a fused
disconnect to the unit. Provide external overcurrent protection to
the unit, using circuit breakers or fuses. If you use fuses, make
sure that they are dual-element time-delay fuses, sized according to
your electrical code. Make sure all electrical connections are tight.
! CAUTION !
Electrical connections must comply with all applicable electrical codes. Voltage
must be within plus or minus ten percent (+/- 10%) of the nameplate rating. Make
sure your installer provides external protection.
