The A-rated emission sound pressure level for all EdEx thrusters is
55 dB (A). This value was determined using an integrated sound
pressure level measuring unit in accordance with DIN 45633 under
the following measurement conditions:

The EdEx thruster (measurement object) ran continuously.

The measurement object was on a table around 0.8 m above the
ground

The measurement microphone was 1.6 m above the ground.

The diagonal gap between the measurement microphone/object
was 1 m.
Explosion-proof EdEx thrusters are limited to the following ambient
temperatures depending on the hydraulic medium:
Table 20: Ambient temperatures for EdEx thrusters
Temperature range
-10 °C to +40 °C
-40 °C to +40 °C
-25 °C to +40 °C
-10 °C to +60 °C
With special measures, operation of EdEx thrusters is permitted up to
100 % humidity.
Special measures (special paint) are required for use in aggressive
ambient conditions (e.g. salty ambient air).
The maximum permissible installation height is 1,000 m above sea
level unless otherwise specified on the type plate.
