SERVICE INSTRUCTIONS
What is ESD?
A sudden transfer or discharge of static electricity from one object to another. ESD stands for
Electrostatic Discharge.
How does ESD damage occur?
ESD can cause damage to sensitive electrical components, but is not dangerous to people.
ESD damage occurs when an ungrounded person or object with a static charge comes into
contact with a component or assembly that is grounded. A rapid discharge can occur,
causing damage. This damage can take the form of immediate failure, but it is more likely
that system performance will be affected and the component will fail prematurely.
How do we prevent ESD damage?
ESD damage can be prevented by awareness. If static electricity is prevented from building
up on you or on anything at your work station, then there cannot be any static discharges.
Nonconductive materials (e.g. fabrics), or insulators (e.g. plastics) generate and hold static
charge, so you should not bring unnecessary nonconductive items into the work area.
It is obviously difficult to avoid all such items, so various means are used to drain off any
static discharge from persons to prevent the risk of ESD damage. This is done by simple
devices: wrist straps, connected to ground, and conductive shoes.
Work surfaces, carts and containers must be conductive and grounded. Use only antistatic
packaging materials. Overall, handling of ESD-sensitive devices should be minimized to
prevent damage.
CAUTION !
STATIC ELECTRICITY can damage circuit
boards and electronic components.
Observe precautions for handling electrostatic-
sensitive devices.
Use proper static-proof bags and boxes.

Service aid
We can offer a number of service tools that will simplify the service.
Soft-starting tool SST 2
Ordering no. 0460 040 880.
The SST 2 is made for the 3000i machine series. (From March 2008 it is delivered with an
adapter cable so that it also can be used for the 4000i, 4001i and 5000i machine series,
from serial no. 803-xxx-xxxx and there above.)
Adapter cable for the 4000i, 4001i and 5000i machine series, ordering no. 0460 042 881.
