Contents of Package
The delivery package includes the actuator and parts 1
through 6 (see Fig. 2), plus two cable grommets and a spare
cable grommet.
RUN MODES
The function selection switch (see Fig. 3) can be used to
place the actuator into either of two different modes:
• Service/Off; or
• the floating/2-position run mode ("Dir" for CCW-closing
dampers or "Rev" for CW-closing dampers).

Power-Off Behavior
If power is removed, the shaft adapter remains in position.
Service/Off
If the function selection switch is set to the "Service/Off"
position, then all rotary movement is cancelled, and all control
signals are ignored, thus allowing the actuator to be manually
operated safely.

5) Removable access cover
6) Anti-rotation bracket
If the function selection switch has been set to one of the two
floating/2-position control settings – and if the actuator is
wired correspondingly (see Fig. 8, Fig. 9, and Fig. 10) – then
as soon as operating power is applied, the shaft adapter will
run according to the control signals applied.
Table 1 describes the behavior ("stops," rotates "CCW," or
rotates "CW") of the N0524 / N1024 in dependence upon the
control signals (switch "open" or "24 Vac/dc") applied to
terminals 3 and 4, the function selection switch setting, and
the manner in which the actuator is wired (either for floating
mode: see Fig. 8; or for 2-position mode: see Fig. 9).

MANUAL ADJUSTMENT
IMPORTANT
To prevent equipment damage, before manual
adjustment, you must remove power or set the
function selection switch to the "Service/Off"
position.
After removing power or setting the function selection switch
to the "Service/Off" position, the gear train can be disengaged
using the declutch button, permitting the shaft adapter to be
manually rotated to any position.
Limitation of Rotation Stroke
Two adjustable mechanical end limits are provided to limit the
angle of rotation as desired (see Fig. 4). The mechanical end
limits must be securely fastened in place.

INSTALLATION
CAUTION
To avoid personal injury (electrical shock) and to
prevent equipment damage, before installation,
you must remove power.
These actuators are designed for single-point mounting.
Mounting Instructions
All information and steps are included in the Installation
Instructions (Product Literature No.: MU1B-0276GE51)
supplied with each actuator.
Mounting Position
The actuators can be mounted in any position (IP54 is
dependent upon orientation; see Fig. 6). Choose a mounting
position permitting easy access to cables and controls.
IP54 IP54IP54 IP54
Fig. 6. Mounting for IP54
NOTE: Further, in order to guarantee IP54, only original
Honeywell grommets may be used.
Anti-Rotation Bracket and Screws
Fig. 4. Mechanical end limits
To ensure tight closing of the dampers, the shaft adapter has
a total rotation stroke of 95°.
INTERNAL END SWITCHES
NOTE: Only those actuators for which "-SW2" has been
specified when ordering (e.g.: "N0524-SW2") feature
internal end switches.
The internal end switches "A" and "B" are changeover
switches which are activated when the shaft adapter moves
past a position of 5° and 85°, respectively (see also Table 5).
3 EN0B-0477GE51 R0408
If the actuator is to be mounted directly on a damper shaft,
use the anti-rotation bracket and screws included in the
delivery package. The min. distance between the center of
the damper shaft and the middle of the anti-rotation bracket is
85 mm; a max. of 108 mm is allowed (see also Fig. 12).
Depending upon your mounting site, the actuator may shift in
position slightly while tightening the screws at the top of the
shaft adapter. The anti-rotation bracket features a T-piece
with a 5-mm-long shank to accommodate for this movement.
It is important to ensure that this play is not impeded.
Universal Shaft Adapter
The shaft adapter can be used for shafts of various diameters
and shapes (round: 8...16 mm and square: 6...13 mm).

WIRING
CAUTION
To avoid personal injury (electrical shock) and to
prevent equipment damage, before wiring, you
must remove power.
Connecting to the Power Supply
In order to comply with protection class II, the power source of
24 V actuators must be reliably separated from the network
power supply circuits as per DIN VDE 0106, part 101.
Access Cover
IMPORTANT
Once the access cover has been removed, please
take care to avoid damaging any of the parts now
accessible.
The access cover can be unscrewed and removed in order to
gain access to the terminal block(s) and perform wiring.
