MTS Insight™ Material Testing System

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.
