Unpacking And Inspection - ABB Symphony Harmony Series Instructions Manual

Unpacking and Inspection

3. Personnel handling assemblies with semiconductor devices
should be neutralized to a static-free workstation by a ground-
ing wrist strap connected to the station or to a good ground
point at the field sight.
4. Do not allow clothing to contact semiconductor devices.
Most clothing generates static electricity.
5. Avoid touching connectors or components.
6. Avoid partial connection of semiconductor devices. Most
devices can be damaged by floating leads, especially the power
supply connector. If an assembly must be placed in a live sys-
tem, it should be done quickly. Do not cut leads or lift circuit
paths when troubleshooting.
7. Be sure to ground any test equipment.
8. Avoid static charges during removal and replacement.
Make sure the assembly is fully clean around its leads, but do
not rub or clean with an insulating cloth.
9. Remove dust from components using an antistatic field
service vacuum.
Unpacking and Inspection
When the MPSIII system is received it should be unpacked and
inspected.
1. Check for any obvious damage to the crate or its contents.
If damage is evident, notify the carrier and an ABB Automation
sales representative.
2. Remove any loose packing from the crate.
3. Inspect the nameplate and verify the unit received matches
the desired function.
4. If storing the MPSIII system prior to installation, leave it in
the original crate, if possible. Store in an area free from corro-
sive vapors and extremes in temperature and humidity.
5. Do not store the MPSIII system in an area that would take
it out of the specifications listed in Table 1-4.
3 - 2
c. Only after firm contact with an antistatic mat and/or
firmly gripped by grounded personnel.
