Please take the following precautions before when servicing the Rack Monitor 88XX:
• Before maintenance entire installation must be shut down/off before proceeding,
• Maintenance must be performed by authorized personnel only,
• All fasteners must be inspected periodically,
• After maintenance is performed, the Rack Monitor 88XX must be tested before the next use,
• Periodical inspection (interval every 6 months) for leakages (especially with heavy rainfall or wind),
• Periodically maintenance is not required but we recommend to check the internals at least once a year, by
tucking all the cables and if there is no corrosion,
• Depending upon the condition of the inside the enclosure after inspection it may be necessary to apply a
coating of corrosion inhibiting spray to the interior components,
• Open and Replace the corrosion inhibiter located on the inside of the door on a regular base.

3.1 Check Points
During maintenance the following items should be checked:
• All earth cables should be rigidly connected and free from corrosion,
• If there is no moisture inside of the enclosure,
• If the main seal is still intact and still soft and smooth,
• If there is no corrosion on any part inside the enclosure,
• Visual inspect all electronic components with special attention for the voltage suppressors (also see
chapter Trouble shooting),
• Check cable more periodically if the rack monitor is exposed to very cold weather conditions.
When maintenance has been performed the following should be done before closing the Rack Monitor 88XX:
• Replace the corrosion protector (should be done every 6 months),
• Put grease on the main seal,
• Make sure that all earth cables are connected,
• Apply coating (if necessary) to the interior components,
Caution:
• Make sure, before closing the enclosure, that the cables do not get stuck between the
door and the bottom side of the enclosure.
• When tightening the bolts, apply the previously mentioned torque.
