MTS Acumen Electrodynamic Test System Load Frame User Guide - Manual (Page 36)

Note:
Local electrical codes supercede any information found here.
Customers should use the power cord kit supplied by MTS for connecting electrical power and ground to the
load frame. Use of power cords with inadequate ratings that are not equivalent to the power cord provided
with your MTS Acumen product could cause a dangerous situation.
Note:
Electrical connections must be made by qualified personnel and is their responsibility for using the
proper power disconnect that conforms to local codes and regulations when connecting the machine
to the buildings main power.
Redundant Protective Earth Ground Connection
A redundant protective earth ground connection is required. MTS Acumen Systems contain high-power drive
systems which create high ground-leakage current; therefore the MTS Acumen load frame requires a permanent
protective earth ground connection in addition to the ground in the AC mains plug/socket connection. An
additional protective earth conductor of appropriate wire gage is supplied with the power cord for this product. At
the load frame, this protective earth conductor must be connected to the grounding post near the AC mains
input of the MTS Acumen load frame. Facility-side connection of the protective earth conductor must be done
in accordance with local electrical codes. If a supplemental ground is not available, MTS offers an optional
permanently wired hard cord kit.
The photos below show the Mains Power Cable with the Supplemental Ground connection.
