Please observe the following points:
The machine must only be installed and operated in a dry and well-ventilated place.
Avoid places near machines generating chips or dust.
The installation site must be free from vibrations also at a distance of presses, planing
machines, etc.
The substructure must be suitable for the drilling machine. Ensure that the floor has suffi-
cient load bearing capacity and is level.
The ground must be prepared in a way that potential coolants cannot penetrate the floor.
Any parts sticking out such as stops, handles, etc. have to be secured by measures taken
by the customer if necessary in order to avoid endangering persons.
Provide sufficient space for the personnel preparing and operating the machine and trans-
porting the material.
Also make sure the machine is accessible for setting and maintenance works.
3.5 Cleaning of the machine
CAUTION!
Do not use compressed air to clean the machine.
Your new drill must be completely cleaned after it is unpacked to ensure that all moving parts
and sliding surfaces are not damaged when the machine is operated. Each unit leaves the fac-
tory with all exposed parts and sliding surfaces suitably greased to avoid oxidation during the
time that elapses before it is placed into operation. Wipe all metallic surfaces with a clean cot-
ton cloth. Clean the plastic parts with cleaning agents suitable for plastic.
3.6 First commissioning
WARNING!
The machine may only be commissioned after proper installation.
If the drilling machine is initially operated by inexperienced personnel, you endanger
both people and the equipment. We do not accept any liability for damages caused by
incorrectly performed commissioning.
3.7 Electrical connection
The machine is installed and ready to operate. Please verify if the type of current, voltage and
protection fuse correspond to the values specified. A protective earth ground wire connection
must be available. Main Fuse 16A. Due to the design, the leakage current is greater than 3,5
mA. We ask for due attention while executing machine tests within the framework of industrial
safety guidelines.
3.7.1 Protective earthing conductor current
The earth leakage current of the SINAMICS V20 inverter may exceed 3.5 mA AC. Due to this, a
fixed earth connection is required and the minimum size of the protective earth conductor shall
comply with the local safety regulations for high leakage current equipment. The SINAMICS
V20 inverter has been designed to be protected by fuses; however, as the inverter can cause a
DC current in the protective earthing conductor, if a Residual Current Device (RCD) is to be
used upstream in the supply, observe the following:
All SINAMICS V20 single phase AC 230 V inverters (filtered or unfiltered) can be operated
on a type A1) 30 mA or type B(k) 30 mA RCD.
All SINAMICS V20 three phase AC 400 V inverters (unfiltered) can be operated on a type
B(k) 30 mA RCD.
