Strain Relief Bracket
You must install the strain relief bracket to ensure that the connector plug does not detach from the instrument during
operation.
Fasten the power cable to the strain relief bracket as shown below, using the supplied tie wraps. This reduces weight
and movement of the AC mains cable at the connector plug.
Make sure the connector
plug is fully inserted.
Install the strain relief
bracket as shown, using
the four hex nuts.
