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 Criterion System must be rated for the loads
Voltage and Current specified in the Electrical Power Requirements Section
(page 22). Size the power system with adequate reserve for future equipment
additions and installation expansion. 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).

Grounding Requirements

All equipment related to the System should be connected to the same electrical
circuit if possible. If there are peripherals that connect to a different electrical
circuit (example; the Integrated Operations Platform is connected to 480 VAC
power but the peripheral is 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. A braided or black ground strap/terminal is provided to tie the load
frame assembly directly to the Integrated Operations Platform to prevent electricl
noise from getting into the system.

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 Requirements

The electrical power of the load frame and Integrated Operations Platform is
provided by a common main power connection. The main power is of 3 phases
and 4 wires (L1,L2,L3 and earth). The line-to-line voltage is 400 V AC 50 Hz or
480 V AC 60 Hz. The customer does not need to consider the power supply of
the PC and the controller, because they are powered by a step-down transformer
inside the Integrated Operations Platform.
