3.4 Mechanical installation
3.4.1 Safety notes
3.4.2 Basic installation considerations
(1) Always use only the holes of the front and rear connectors to install the actuator. First check the model
number on the product label (section 3.1), and then refer to the model coding (section 6.2) to identify the
connector type of the actuator, so that you can find the dimensions specification from the figures below.
● Front connector types
● Rear connector types
(2) Make sure the actuator is installed in a way that allows you to access the anti-pull lid so that it can be
removed to plug in and out the cables (section 3.4.4)
(3) Users may need to manually adjust the actuator in the future, so there must be enough free space around the
manual drive connector to operate it (section 3.4.5)
● Do not perform mechanical installation when the actuator is powered.
● Complete the mechanical installation properly before proceeding to the
electrical installation steps.

3.4.3 Force and orientation
(1) The actuator can be installed in any orientation and can withstand push and pull loads.
(2) When installing the actuator, make ensure that the force of the load acts on the central axis of the extension tube
and rear connector.
(3) Use only solid and sized mounting pins. The mounting pins must be strong enough to support the load and
prevent it from falling off after installation.
(4) The mounting pins must be parallel to each other on the same plane, as shown in the sketch below.
(5) If the actuator is used on the equipment to rotate with the mounting pin as the axis, it must be ensured the
housing and other mechanical parts will not interfere and damage the actuator and equipment in the full range
of movement.
3.4.4 Cables and anti-pull lid
Before the actuator is shipped, the power cable and signal cable have been plugged in and the anti-pull lid has been
installed. Only the CAN Bus version (control option J00) needs to remove this lid and unplug the power cable when
the hardware address selection (see 4.2.2.2) is required. But please note that when installing the actuator, you must
ensure that there is enough space to remove the anti-pull lid with tools.

3.4.5 Installation and operation of hand crank
(1) When installing the actuator, please make sure that there is enough space between the rear connector and any
objects behind it so that the hand crank can be operated.
(2) Please use a flat-head screwdriver to remove the cover and connect with a 6mm hexagon socket.
(3) Use a wrench to operate as a hand crank.
(4) Under the maximum load of the actuator, the maximum torque required to drive the extension tube with the
hand crank is about 1.4Nm.
(5) The distance traveled by the actuator per rotation of the hand crank is related to the gear ratio options of the
actuator. Please refer to the table below.

● Before using the hand crank, be sure to turn off the actuator power. Do not
apply torque exceeding 1.7Nm on the hand crank.
● Do not move the extension tube to both ends of the stroke, otherwise the
actuator might be damaged.
● Do not use any type of automatic drill or power tools to drive the manual
crank.

3.5.3 Fuse specification
Install a slow-blow fuse of this specification between the actuator and the power supply for protection.
www.moteck.com

● It is recommended to install an emergency stop switch at a suitable location
of the power supply line.
● Do not install or wire the actuator without cutting off the power supply.
● Before controlling the action of the actuator, it must be noted that the
actuator and its connected mechanical moving parts are not blocked by
other objects, and no one enters the dangerous area.
● It is forbidden to wind the signal cable with the power cable to avoid
interference with the signal.
● Avoid using the vehicle as a ground to reduce the risk of interference.
● The longer the power cord length or the smaller the wire diameter, the
worse the voltage drop. When the voltage of the power supply is low, it is
more likely to cause insufficient voltage and cause malfunctions.
● Relays or other coils on operating equipment should have spark protection
to avoid interference.
● In order to achieve the longest service life, the actuator should not be
stopped by frequent hard collisions. Before the actuator moves to the
target position or both ends of the stroke, the user's automatic control
device should cut off the power of the motor in advance according to the
absolute position information, and use the inertia to make the actuator stop
gently.
● It is forbidden to use Pulse Width Modulation (PWM) as input power to
MK35, otherwise it will cause malfunction and cause permanent damage.
● Before using the hand crank, be sure to turn off the actuator power. Do not
apply torque exceeding 1.7Nm on the hand crank.
● Do not move the extension tube to both ends of the stroke, otherwise the
actuator might be damaged.
● Do not use any type of automatic drill or power tools to drive the manual
crank.

3.5.4 Electrical connections
Actuator is equipped with a power cable and a signal cable. One end of each cable has been plugged and fixed
on the actuator before shipment, and the other end are bare wire contacts for customers to connect power and
signal transmission. Please check the model number on the product label (section 3.1) first, then refer to the
model coding (section 6.2) to identify the control options of the actuator, and connect the power cable and signal
cable correctly according to the description of each control option (section 3.6).
3.5.5 Wire specification of power cable and extension cord
To avoid malfunctions caused by voltage drop, the cross-section of the power cable wire must be large enough.
The cross-section of the MK35 power cable wire is 2.0mm² (14AWG) and the maximum length is 3 meters. If the
customer must connect an extension cord, the wire requirements of the extension cord are as follows.
3.5.6 Inrush current
www.moteck.com
10
● When the actuator starts, an inrush current of about 0.2 seconds will be
generated. The starting inrush current of MK35 can reach 3 times of the
maximum current under the rated load of the actuator.
● If a circuit board power supply is used, the specifications must be sufficient
to handle the inrush current. If batteries are used as the power source,
inrush current will not be a problem. Besides, the connectors, switches and
relays selected by user must also be able to withstand the inrush current.

Option D00 controls the actuator to extend or retract by switching the polarity of the input DC power.
(1) When the actuator reaches the limit position at both ends of the stroke, it will still stop by itself, but it will not
output a signal of reaching the limit.
(2) Do not adjust the input voltage in an attempt to control the speed of the MK35 DXX control options.
(3) The D00 option does not include a signal cable, and the port has a waterproof cap.

In addition to all the functions included in the D00 and D0L options (section 3.6.2 & 3.6.3), the DPL option is also
equipped with a potentiometer, which allows the user's control device to know the absolute position of the actuator
at any time, and can be used to determine the speed and direction of the actuator's movement.

3.6.7 Control option S0L (Low current signal control, with EoS signal output)
Option S0L uses a low current (<10mA) input signal to control the extension, retraction or stop of the actuator,
cannot be switched the polarity of the input DC power, and there is an arrival signal output when it reaches the end
of stroke (EoS). However, if the user does not need EoS signal, these two signal output wires can be ignored and
unconnected. This does not affect the other functions of the actuator, and the actuator will still stop when it reaches
the limit positions at both ends of the stroke.
In addition, the actuator also has the following functions:
● At both ends of the mechanical stroke and within the full stroke range, when the current exceeds the factory
preset value of the rated load (overload condition), the actuator will automatically stop.
● When the input voltage exceeds its normal working range, the actuator will stop running. After the correct
voltage input is restored, the operation signal must be re-sent to restore control.
● With automatic soft start function, make the equipment move smoothly.
● Wiring
● The polarity of the input DC power must be fixed in accordance with the
specified connection method, and the polarity cannot be switched at any
time.
● It is forbidden to adjust the input voltage in an attempt to control the speed
of the MK35 SXX control options. The battery or full-wave rectified DC
power used must be within acceptable voltage range, otherwise the
actuator will stop operating.
