Electrical Requirements - Hypertherm HyPrecision 100D Instruction Manual

Electrical Requirements

When connecting power to the pump it is the buyer's responsibility to investigate
and comply with all local codes. The power requirements are listed on the serial
plate on the back of the pump as well as on the inside of the electrical enclosure
door.
CAUTION
Three phase power connection
Each of the three phases of input power are connected to the three (3) terminals at
the top of the motor switch (right). Additionally a ground leg must be attached to
the grounding lug inside the electrical cabinet.
Pumps equipped for certain foreign power may have slightly different connection
requirements. Always refer to the electrical schematic for the machine to verify
proper connection.
Schematics are supplied in the Drawings and Parts Lists section of the manual and
an additional copy is included inside the electrical cabinet.
Location Requirements
•
The pump must be placed in a location, which allows access to all sides for service.
•
The pump should have a minimum 36 in. clearance surrounding the machine, free of all obstacles,
to allow room for service. See the Pump Requirements section under Specifications.
•
The pump should not be placed in any environment where the temperature is below freezing. If
freezing temperatures are expected before operating again, drain all water lines and filter housings
after work is completed for the day.
If a water line, fitting, or valve may be frozen, DO NOT operate the machine. The
system must be thawed until water flows freely through the entire water circuit.
WARNING
Recommended Tools
Most maintenance of the pump can be accomplished using standard tools. Refer to the recommended
tools list in the Drawings and Parts Lists section. Contact Hypertherm to purchase replacement
specialty tools for intensifier and bleed-down valve servicing.
