MTS Exceed™ Series 40 Site Preparation Guide
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 Exceed Test System must be rated for the
voltage and current specified in the
page 21. Size the power system with adequate reserve for future equipment
additions and installation expansion. Power of load frame console must be
considered in the distribution system, with emphasis on providing "interference
free" electrical power to the controls. Plan routing of power cables away from
instrumentation cables (for example, transducer cables). Avoid long parallel runs
of power cables in close proximity to instrumentation cables. Power cables
should be separated from instrumentation cables by 0.3 to 1 m (1 to 3 ft).
The customer is responsible for providing an electrical power disconnect 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
characteristics). 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.
All equipment related to the load frame should be connected to the same
electrical circuit if possible. If the computer, monitor or other peripherals are
connected to a different electrical circuit (example; the load frame is connected to
208 VAC power but the computer and monitor are connected to 120 VAC power)
make sure there is no voltage difference between the two different grounds. If
voltage is present, damage could occur to the electronics in the machine, the
computer and monitor or the peripherals being used. This must be resolved
before turning on the equipment.
Where electrical power is of poor quality (noise spikes, poorly regulated, and so
forth) or the ground system in the facility contains electrical noise, attach a 4
AWG wire directly to a good earth ground point such as a 2 m (6 ft) copper
grounding rod driven at least 2 m (6 ft) into the ground. Grounding must conform
to local electrical codes.
Electrical power to the load frame should be free from outside RF Interference
and match the specifications in the table on page 21 for each frame type. An
isolated power source or uninterruptible power supply is recommended if it is
desirable to maintain load frame power when power fails interrupt. Make sure
that the service to the MTS Exceed Test System is not on a line that can be
accidentally shut off. The MTS Exceed Test System and the computer
workstation should both be powered from the same electrical circuit.
