Electrical Power Distribution
Note Electrical connections must be made by qualified personnel and conform
to local codes and regulations. Local electrical codes supersede any
information found here.
The input line voltage to the MTS Ex eed Test System must be rated for the
voltage and urrent spe ified in the “Ele tri al Power Requirements” se tion on
page 21. Size the power system with adequate reserve for future equipment
additions and installation expansion. Power of load frame onsole must be
onsidered in the distribution system, with emphasis on providing “interferen e
free” ele tri al power to the ontrols. Plan routing of power ables away from
instrumentation ables (for example, transdu er ables). Avoid long parallel runs
of power ables in lose proximity to instrumentation ables. Power ables
should be separated from instrumentation ables by 0.3 to 1 m (1 to 3 ft).
Electrical disconnect
The ustomer is responsible for providing an ele tri al power dis onne t that is
easy to operate and easy to rea h. It must also meet IEC 60947-1 and IEC 60947-
3 standards.
Re ommended ir uit breakers would be ones that are of the thermal magneti
type with hara teristi s suitable for large indu tive loads (D-type trip
hara teristi s). If fuses are used it is re ommended that they are of the time
delay type with dual elements. These re ommendations should be followed to
avoid nuisan e tripping.
Grounding Information
All equipment related to the load frame should be onne ted to the same
ele tri al ir uit if possible. If the omputer, monitor or other peripherals are
onne ted to a different ele tri al ir uit (example; the load frame is onne ted to
208 VAC power but the omputer and monitor are onne ted to 120 VAC power)
make sure there is no voltage differen e between the two different grounds. If
voltage is present, damage ould o ur to the ele troni s in the ma hine, the
omputer and monitor or the peripherals being used. This must be resolved
before turning on the equipment.
Where ele tri al power is of poor quality (noise spikes, poorly regulated, and so
forth) or the ground system in the fa ility ontains ele tri al noise, atta h a 4
AWG wire dire tly to a good earth ground point su h as a 2 m (6 ft) opper
grounding rod driven at least 2 m (6 ft) into the ground. Grounding must onform
to lo al ele tri al odes.
Load Frame Power
Ele tri al power to the load frame should be free from outside RF Interferen e
and mat h the spe ifi ations in the table on page 21 for ea h frame type. An
isolated power sour e or uninterruptible power supply is re ommended if it is
desirable to maintain load frame power when power fails interrupt. Make sure
that the servi e to the MTS Ex eed Test System is not on a line that an be
a identally shut off. The MTS Ex eed Test System and the omputer
workstation should both be powered from the same ele tri al ir uit.
