purpose or the motor shall be monitored by the thermal protectors in the stator windings
and at the bearings.
c. The permissible operating temperature of the connection cable and gland shall be at least
90 °C.
5. A routine overpressure test must be conducted on all production enclosures, according to the
requirements of IEC 60079-1:
a. Stator housing: 3.8 Bar
b. Small terminal box: 3.5 Bar
c. Large Terminal box 5.3 Bar.
6. The dimensions of the flameproof joints are in parts other than the relevant minimum or maximum
values of IEC 60079-1:2007. For information on the dimensions of the flameproof joints contact
the manufacturer.
7. All cable entries shall be fitted with suitably certified glands or closed with suitably certified
blanking elements.
8. The internal bush(es) / glands as indicated by the manufacturer and covered by IECEx PTB
06.0093U and/or IECEx SIR 07.0096X must be utilised in the entries between the different
flameproof compartments.
Description continued:
The stator housing of the motor is designed in type of protection flameproof enclosure.
It is equipped with a terminal box which is a separate compartment in type of protection flameproof
enclosure.
The terminal box is designed in different variations. The variations differ in the size and in the
equipment with bushings, terminals and cable glands.
The motor type dksV36TM/2-4 is equipped with the large box and the motor typ dksV36TM/3-6 is
equipped with the small box.
The motor type dksV36TM/2-6
The stator housing of the motor is designed in type of protection flameproof enclosure. It is equipped
with the small variant of the terminal box which is a separate compartment in type of protection
flameproof enclosure.
Temperature control:
Type dksV36TM/2-4
For direct temperature control the stator winding is equipped with 3 temperature sensors (PTC
thermistors DIN 44081-120).
Type dksV36TM/2-6
For direct temperature control the stator winding is equipped with 3 temperature sensors (PTC
thermistors DIN 44081-120) and with 1 temperature sensor (PTC thermistors DIN 44081-100) at each
bearing.
Type dksV36TM/3-6
For direct temperature control the stator winding is equipped with 3 temperature sensors (PTC
thermistors DIN 44081-140) and with 1 temperature sensor (PTC thermistors DIN 44081-100) at each
bearing.
Optionally the motor is equipped with thermal protectors (break contacts) instead of temperature
sensors (PTC thermistors). The number, the location and the rated operating temperature of these
thermal protectors are identical with those of the temperature sensors.
Optionally the motor is equipped with additional, identical temperature sensor circuits and/or thermal
protector circuits as spare circuits.
The thermal protectors are connected in series.
The temperature sensors are connected in series and they are connected to a control unit which is
suitable for this purpose.

The specifications of the duty ratio (40 %), of the rated power (30 kW) and of the permissible upper limit of
the ambient temperature range (40 °C) are maximum values. A simultaneous utilization of these maximum
values will lead to a shut-off by the direct temperature control. The user has to choose a mode of operation
which normally does not lead to a shut-off by the direct temperature control.
