TRAK TRL Lathe, ProtoTRAK RLX CNC Safety, Installation, Maintenance, Service & Parts List
For a newly installed machine, check the level once every week. Once the foundation is rigid enough, then
check it once per month.
2.10 Electrical Connection
The TRAK Lathe can only be configured for 208-240 volt 3 phase electricity. To run at 440V, you will need a
step down transformer from 440V to 208V.
DANGER!
Be certain that 208-volt electricity (typical range 208 – 240V) is used only with a
machine labeled 208 volts at the motor and at the electrical cabinet on the back of
the column.
WARNING!
440 Volts will damage expensive electrical components if machine is wired by
mistake as 440 volts. These components are not covered under warranty.
DANGER!
The 208-240 volt line must originate from a dedicated and independent fused box
with a manual shut-off lever. It is the responsibility of the purchaser to supply a
wired box that meets all local codes and regulations.
The 208-240 volts wires to the machine through the electrical box located on the back of the column. The
wire enters the main on/off switch through a hole on the top of the box. The ground wire should be
connected at the top or bottom of the breaker bracket.
DANGER!
Only a qualified electrician should wire the 208-240 volt 3-phase electricity.
Southwestern Industries recommends the machine be earth grounded by driving a copper rod into the
ground. It is the responsibility of the customer to install this rod.

Phase Converters
For those machines that will be run with a phase converter, it must be a CNC rated rotary type
rather than a static phase converters. CNC rated rotary phase converters allow for varying loads in
the system. A CNC rated phase converter also regulates the new leg created so it does not end up
being too high or low of a voltage. The electrical load on the machine will vary based on the type of
cut taken and the speed of the motor. Static phase converters can only be used on machines with a
non-varying load. Please contact your local phase converter distributor for precise sizing.
