Degree Of Protection - Siemens SIMOTICS L-1FN3 Configuration Manual

Requirements placed on the anti-corrosion agent
The anti-corrosion agent must fulfill the following requirements:
● The basis is ethylene glycol (also called ethanediol)
● The water and anti-corrosion agent do not segregate
● The freezing point of the water used is reduced to at least -5 °C
● The anti-corrosion agent used must be compatible with the fittings and cooling system
hoses used as well as the materials of the motor cooler
Check these requirements, especially in regard to material compatibility, with the cooling unit
manufacturer and the manufacturer of the anti-corrosion agent!
Suitable mixture
● 25% - 30% ethylene glycol (= ethanediol)
● The water used contains a maximum of 2 g/l dissolved mineral salt and is largely free
from nitrates and phosphates
Manufacturer recommendations: see appendix
3.2

Degree of protection

NOTICE
Damage to the motor caused by pollution
If the area where the motor is installed is polluted and dirty, then the motor can malfunction
and clog up.
• Keep the area where the motor is installed free of all dirt and pollution.
Primary section
The primary sections satisfy the requirements for IP65 degree of protection in accordance
with EN 60529 and EN 60034-5.
Secondary sections
The secondary sections are protected against corrosion to a large degree via structural
measures. Ensure that the air gap remains free of chips and other foreign bodies. Provide
suitable covers for this. As of a distance of 150 mm from the surface of the secondary
section, ferromagnetic particles are generally no longer attracted.
Avoid using abrasive or corrosive substances (e.g. acids).
