SIEMENS DA 64 – 2002/2003

Version D 3/6

3.3 Degrees of protection

The IP number defines the

degree of protection against the

ingress of dirt, foreign bodies,

water etc. (Ingress Protection;

IP) for the associated drive

inverter.

MICROMASTER and

MICROMASTER Vector have

degree of protection IP20 (this

corresponds to the US NEMA 1

Class).

MIDIMASTER Vector models

with degree of protection IP21

(this corresponds to the US

NEMA 1 Class) or IP56 (this

corresponds to the US NEMA

4/12 Class).

The significance of the

individual IP class numbers

referred to the protection

against the ingress of dirt etc. is

explained in Table 4:

0 No specific protection

1 Protected against solid

objects with a diameter of 50

2 Protected against solid

objects with a diameter larger

or equal to 12 mm

3 Protected against solid

objects with a diameter larger

or equal to 2.5 mm

4 Protected against solid

objects with a diameter larger

or equal to 1 mm

5 Protected against dust

(limited ingress)

6 Protected against dust

(totally)

Fig. 2: MIDIMASTER Vector with degree of protection IP56 – installed in a housing

MIDIMASTER Vector, with degree of protection IP56/NEMA 4/12, can be accommodated in a larger housing, whereby the heatsink

protrudes through the rear cover of the unit. This ensures that the heat from the drive inverter is dissipated to the ambient air

without the need for additional cooling fans. This guarantees the IP56 degree of protection. Only the minimum mounting clearance

of 150mm to the next drive unit must be observed.
