#### Electrostatic sensitive devices (ESD)

The built-in components may contain electrostatic sensitive components. Please be sure to observe the applicable ESD protection regulations.

Do not touch any ESD-sensitive components or connection points!

#### Transport

Check the system immediately upon receipt for possible transport damage. When unpacking, take particular care with sensitive components such as cables, plugs, encoders and motors. It is not permitted to commission damaged products.

#### Handling

Linear motor axes must always be transported in a horizontal position, as the carriage can fall uncontrollably into the mechanical stop in a vertical position.

There is a risk of hands and fingers being squeezed!

#### Magnetic fields

Linear motor slides generate magnetic fields below the slide due to their permanent magnets. However, there are no magnetic fields on the top of the slide or below the base plate.

#### Measuring system

The magnetic measuring system is sensitive to external magnetic influences and can be damaged if handled incorrectly. Avoid contact between magnetic fields - for example from other motors or magnetic torches - and the magnetic scale tape on the axis.
{% endcolumn %}
{% endcolumns %}

{% columns %}
{% column %}

{% endcolumn %}

{% column %}

#### Mechanical assembly

Protective gloves and suitable tools must be used for mechanical assembly.

The carriage of the linear motor axes must never be pulled off the rail. This will cause irreparable damage.

Additional applications are mounted using the threaded holes and locating holes provided for this purpose.

#### Flatness base plate

If the linear motor axes are mounted on a base plate, this must have a flatness of 0.01mm over a legth of 200mm. Otherwise, the linear motor axis can be distorted when screwed tight and the guides can jam. This increases wear, reduces lifetime and can damage the guides.

{% endcolumn %}

{% column %}

#### Flatness component assembly

The same requirements apply to the contact surface of components that are screwed onto the slide of a linear motor axis. This contact surface must have a flatness of 0.01mm over a legth of 200mm.
{% endcolumn %}
{% endcolumns %}

{% columns %}
{% column %}

{% endcolumn %}

{% column %}

#### Flatness - practical test

Before assembly, check how smoothly the carriage can be moved by hand. Then tighten the screws and check the run again. There should be no noticeable difference. Otherwise, the contact surface must be reworked.

#### Safety instructions for the power supply

A defective or incorrect power supply can cause irreparable damage to the machine.

The earthing cable must be always connected to the system.

Never pull out the plug during operation! There is a danger to life and a risk of serious injury and damage to property.

Electrical connections must never be disconnected when energised. Switch off the power supply and wait at least 10 seconds before disconnecting.

The drives may only be connected to the specified power supply.

Plugs with a screw lock must be screwed on properly.

Only use original Jenny Science AG cables and do not make any modifications to them.

#### Earthing concept

* The 0 volt connection of the logic supply (pin 1) and the 0 volt connection of the power supply (pin 3) have to be connected to the ground/chassis star point of the switch cabinet.
* The XENAX® servo controller must be screwed onto a conductive background, which is connected to the GND/chassis star point of the switch cabinet. The motor cable must be connected to the shield clamp.

{% endcolumn %}

{% column width="50%" %}
Maintenance work must only be carried out when the axles are at a complete standstill. The axis must not be in control mode and must be disconnected from the power supply first.

The linear motor system must not be immersed in liquids or sprayed for cleaning.

#### Cleaning

Coarse contamination must always be removed with a soft brush or oil-free compressed air. Depending on the environmental conditions, regular cleaning is necessary to prevent foreign particles from entering the guide system or electronics or settling on the magnetic plate..

#### Lubrication of roller guides

The initial lubrication by Jenny Science on delivery is sufficient for several years, depending on the load.

The ELAX® cross roll cages are force centered through gear pinions and gear rods. The lubrication intervals depend on multiple parameters, such as operational demands, dynamics, operational temperature, pollution etc. Preventively we suggest lubricating the guides every 12 months or every 100 million cycles.

Clean the guides before lubricating. Relubrication is carried out using a dispensing gun and a suitable grease cartridge. Position the carriage so that you can access the guide rails on the carriage and those on the monoblock, on the left and right. Now apply some grease to the flat running surface of the guide rails by pressing the dispensing gun. Then move the carriage back and forth and remove the excess grease with a cotton swab.

<h4 align="right">Lubrication of magnetic weight compensation</h4>

The initial lubrication by Jenny Science on delivery is sufficient for several years, depending on the load.

Two needle holes are provided for lubricating the recirculating ball bearing guide installed in the weight compensation. To do this, fully retract the carriage, place the dispensing gun on the respective needle hole and apply the lubricant by actuating the dispensing gun.

{% endcolumn %}

{% column width="50%" %}
The linear motor axis from Jenny Science AG contains permanent magnets.

People with implants that can be magnetically influenced or with prostheses that contain ferromagnetic components are at risk due to the magnetic fields that occur (>0.5mT) and must ensure a safety distance of at least 50mm.
{% endcolumn %}

{% endcolumn %}

{% column width="50%" %}
Due to the high magnetic field strengths, large attractive forces occur particularly in the immediate vicinity (distance approx. 50 mm) of the magnetic tracks. It must therefore be strictly ensured that objects made of steel or iron (e.g. watches, rings, etc.) as well as technical devices (e.g. computers, credit cards, hard discs, etc.), which could be attracted, influenced or destroyed by the magnetic field, are not brought into this area with the free hand. An appropriate safety distance must be maintained.

{% endcolumn %}

{% column width="50%" %}
The surfaces of the motors can become hot during operation of the axis. The surface temperature of the motor can reach up to 80°C.

Monitoring devices and the error messages of the control units must be checked continuously. Switch off the motor if there are any changes compared to normal operation.
