8 PSTX ENCLOSED SOFT STARTER
Miscellaneous information
If your enclosure is equipped with forced ventilation
for keeping the starter and other components
within their thermal recommendations, the cooling
fan(s) used to ventilate your enclosure need to be
cleaned periodically. Cleaning the cooling fan(s)
is recommended to keep the proper amount of air
circulating through the enclosure. The PSTX soft
starters have fans for ventilation internal to the
PSTX device.
ABB recommends that all power connections be
checked for proper tightness every 6 months due
to thermal cycling that may occur during normal
operation.
Inspection #2
Prior to start-up of your PSTX soft starter panel,
inspect the following:
• The mechanical installation for any safety issues
and any violation of local or national code.
• The electrical installation for proper connections
and any violation of local or national code.
• Proper grounding of equipment.
• All field wiring for tight and proper connections
(no split wire ends that may come into contact
with adjacent connection points).
• No loose hardware, metal shavings or wiring
chips.
• All factory wiring for proper tightness that may
have become loose due to shipping vibration.
