Engineering notes
This section explains general and system-specific regulations for mains and
operating voltages. It also contains important information on your own safety and
that of your plant.
Use these actuators as described in the basic system documentation for the
applied control systems. In addition, take account of all actuator-specific features
and conditions as described in the brief description on the front page of this data
sheet (bold print) as well as the sections "Use", "Engineering notes", and
"Technical data".
Sections flagged with the warning symbol to the left contain safety-related
requirements and restrictions that must be adhered to at all times to prevent
physical injury and equipment damage.
Operate the actuators only on safety extra-low voltage (SELV) or protective extra-
low voltage (PELV) as per HD 384.
The actuators are double-insulated and there is no connection for the protective
ground.
Apply only mains voltage or protective extra-low voltage to the switching outputs of
the auxiliary switch. Mixed operation is not allowed. Operation at various phases is
not allowed.
Do not open the actuators!
•
The actuators are maintenance-free.
•
Only the manufacturer may carry out repair work.
•
Opening the actuator will void the warranty.
Up to 10 actuators of the same type can be electrically wired in parallel; cable
length and cable cross-sections must be observed.
Selection of the actuator depends on several torque factors. After obtaining the
damper torque rating (Nm/m²) from the manufacturer and determining the damper
area, calculate the total torque required to move the damper as follows:
Non-spring return damper actuators:
IF total torque (SF¹):
Use type:
2 Nm
GSD…1.1A / GSD…6.1A (2 Nm)
GXD…1 (1,5 Nm)
5 Nm
GDB…1 (5 Nm)
10 Nm
GLB…1 (10 Nm)
15 Nm
GEB…1 (15 Nm)
25 Nm
GBB…1 (25 Nm)
35 Nm
GIB… 1 (35 Nm)
¹ Safety factor SF: When calculating the required torque, non-definable variables
such as slight misalignment, damper age, etc. must be included as a safety factor.
We recommend a safety factor of 0.8 (or 80 % of the torque characteristic).
