1 General Information
1.1 Safety Notes
Information about safety regulations, symbols, copyrights, protection rights,
usage location conditions and notes on resistance welding can be found in the
back section of these operating instructions.
Please read this information carefully before using these operating instructions.
These operating instructions should help you familiarize yourself with the system and
take advantage of its application possibilities when used as directed.
It contains important notes to help operate the unit safely, properly, and economically.
Observing the notes will help avoid risks, decrease repair costs and down times, and
enhance reliability and the service life of the unit.
It is a rule: Safety first!
Warning
Incorrect or inappropriate configuration, installation, settings, handling or use can cause
mechanical, electrical or thermal hazards, which may result in serious damage or injury.
Ensure the correct execution of these points and follow the respective notes in the
operating instructions.
Danger
Do not put the system into operation before you have read the operating instructions!
Danger Persons with cardiac pacemakers and metallic implants are prohibited from
approaching to within a radius of at least 5 m of welding equipment!
Crushing Hazard
There is a risk of crushing during the adjustment movement due to closing electrodes,
stops for limiting adjustment or stroke movement and the stop on the basic pincers unit
for limiting floating movement.
Warning
This Class A welding equipment is not supposed to be used in living quarters, where
the power supply is carried out by a public low voltage supply.
There it can be difficult to ensure electromagnetic compatibility because of conducted or
radiated disturbances.
Warning

1.2 Installation Notes
Please observe the following additionally to the points in chap. 5.1:
Ventilation:
To ensure adequate ventilation of the weld control and motor control units, the distance
on the side must be at least 40 mm and behind at least 100 mm.
19“ units (installation in a control cabinet):
ISQ20 - 1 U distance upwards
MNC (motor control) – at least 40 mm distance on the lateral ventilation slots
If the distances are too small, it can lead to increased temperatures in the inside of the
unit. This can affect the functionality.
Cable routing:
For the cable routing ensure an appropriate separation of control and field bus cables to
power cables, motor cables and cables with welding current.
EMC guidelines – and thus also the distances to arising magnetic fields – have to be
observed.
An appropriate shielding has to be scheduled if necessary.
