Preventative Maintenance
Check
Action to be Taken
Visually Check chassis for loose or damaged parts
/ hardware.
Note: Internal inspection is not required.
Parts should be repaired as required. If internal
damage is suspected, these parts should be
checked and repairs made if necessary.
Inspect cooling vents.
Remove any accumulated material from vents.
Check for fluids or electrically conductive material
exposure.
Any fluids or electrically conductive material must
not be permitted to enter the Npaq MR.
Visually inspect all cables and connections.
Tighten or re-secure any loose connections.
Replace worn or frayed cables. Replace broken
connectors.
Cleaning
The Npaq MR chassis can be wiped with a clean, dry, soft cloth. The cloth may be slightly moistened if
required with water or isopropyl alcohol to aid in cleaning if necessary. In this case, be careful not to allow
moisture to enter the Npaq MR or onto exposed connectors / components. Fluids and sprays are not
recommended because of the chance for internal contamination, which may result in electrical shorts and/or
corrosion. The electrical power must be disconnected from the Npaq MR while cleaning. Do not allow
cleaning substances or other fluids to enter the Npaq MR or to get on to any of the connectors. Avoid
cleaning labels to prevent removing the label information.
