Rack and Safety Enclosure Maintenance
There are no specific parts in the Rack and Safety Enclosure that require periodic
replacement. Nevertheless, regularly check all parts in the system for changes
like broken cables, defective fans, loose connections, etc.
Operate the DPT Rack and Safety Enclosure only in a clean environment with air
that contains no dust or aggressive industrial gases. Clean the system rack and
all fans and air exhaust vents periodically to guarantee appropriate air flow
through the test system. After any maintenance work, the responsible safety
engineer must approve the system before recommissioning.
Maintenance of the Safety Hood
Regularly check the Safety Hood as follows:
–
Verify the functionality of the open and close mechanism.
–
Ensure the pressurized cylinders are able to hold the cover open.
–
Verify that the safety switch is functional and the cover remains locked
when power is off.
Recommended Maintenance Intervals
– Weekly: Check the safety equipment and the proper function of all safety
features at the test system. Check all strain reliefs. Visual inspection for
changes like bent pins or contacts, defective connectors, cracks on the
enclosure or other signs of wear.
– Monthly:
Check all mechanical parts in the system. For example loose
screws on the rack, loose connectors. Visually inspect the system wiring
and isolation.
– Every 6 months:
Clean the system and the fans from dust. Check all
connectors and contacts for abrasive wear. Clean if necessary. The two
fans at the bottom of the rack (one fan on each side) have foam filters. No
other fans or vents have filters. Clean dust from the filter with a vacuum or
with a damp cloth.
Some of the material in the safety enclosure can generate static
electricity. Take care if you are using ESD sensitive devices in its
vicinity.
Do not wash the air filters or install the filters in the chassis if they
are wet.
