Safety Instructions
1.3. PRELIMINARY RECOMMENDATIONS
DANGER!
Only qualified personnel familiar with the SSW7000 soft-
starter and associated equipment should
plan or implement the installation, start-up and subsequent maintenance of this equipment.
These personnel must follow all the safety instructions included in this manual and/or defined by
local regulations.
Failure to comply with these instructions may result in life threatening and/or equipment damage
NOTES!
For the purposes of this manual, qualified personnel are those trained to be able to:
1. Install, ground, energize and operate the SSW7000 according to this manual and the effective
legal safety procedures
2. Use protective equipment according to the established standards.
3. Give first aid services.
DANGER!
Always disconnect the input power before touching any electrical component associated to the
SSW7000. Follow the SSW7000 disconnection sequence, according to the item 10.4.1 - SSW7000
Disconnection Sequence.
High voltages and rotating parts (fans, if installed) may be present on the SSW7000 even after shut
down or power disconnection. Wait at least 3 minutes for the complete discharge of the capacitors
and the stopping of the fans.
Always connect the equipment frame to the protective earth (PE) at the suitable connection point.
ATTENTION!
Electronic boards have components sensitive to electrostatic discharges. Do not touch directly on
components or connectors. If necessary, touch the grounded metallic frame before or use an
adequate grounded wrist strap.
Do not perform any high pot tests with the SSW7000!
If it is necessary, consult WEG.
NOTE!
Soft-starters may interfere with other electronic equipments. In order to minimize these effects, take
the precautions recommended in the chapter 5 - Installation and Connection.
NOTE!
Read the user's manual completely before installing or operating the SSW7000.
