MTS Insight™ Material Testing System 42
Controller Connections
Installation
100 kN through 300 kN
Important Local electrical codes supersede any information found in this
manual.
Electrical connections must be made by qualified personnel and is their
responsibility for using the proper power disconnect along with the correct size
and type of wire and conduit that conforms to all their local electrical codes when
connecting the machine and transformer to the buildings main power.
Wire sizes
The minimum wire gauge inside conduit requirements are:
• MTS Insight 100—14 AWG
• MTS Insight 150—12 AWG
• MTS Insight 200—10 AWG
• MTS Insight 300—8 AWG
Ground wire needs to be the same gauge wire or larger than those listed above for
the associated frame size.
Electrical disconnect
The electrical box must have a power disconnect switch that is easy to operate
and easy to reach. It must also meet IEC 60947-1 and IEC 60947-3 standards.
Recommended circuit breakers would be ones that are of the thermal magnetic
type with characteristics suitable for large inductive loads (D-type trip
characteristic). If fuses are used it is recommended that they are of the time delay
type with dual elements. These recommendations should be followed to avoid
nuisance tripping.
For the Insight 200 and 300 the electrical box over current device must be Branch
circuit rated.
