4. Electrical Interface
PWE and aviation plug interface waterproof precautions:
1. PWE interface and air plug interface are equipped with dust plugs from the factory. If
the dust plug does not fall off, the protection level of IP64 can be achieved; at the
same time, when the PWE cable and the air plug cable are well connected, IP64 can
also be achieved;
2. After the dust plug is removed, the protection level of IP64 cannot be achieved. If it
encounters spraying or flushing at this time, it will cause water to enter the product
and affect the function;
3. Ensure that the water circuit is connected well, and the water pipe interface is
tightened before removing the dust plug to prevent the water pipe from accidentally
loosening and water rushing to the interface, causing the product to enter the water;
4. When adjusting the wiring, remove the dust plug for wiring. It is recommended to
keep the removed dust plug of the PWE interface. Install the dust-proof plug as soon
as possible after the stitches are removed to prevent accidental water ingress in the
transfer, water connection and other links.

Notice:
The above wiring operations should only be performed by trained
and professional personnel.
When the cutting head is connected to the BCS210E, the BCS210E
must be powered off.

5. Cutting head installation
5.1 Preparation before operation
The following objects are required before operation:
Cutting head;
Clean workbench (clean workbench type: vertical purification; cleanliness level: ISO 5, 100; average wind speed ≥
0.4m/s);
Cleaning kit: strong light flashlight, absolute ethanol (or IPA), dust-free purification cotton swab, dust-free cloth,
compressed air dust removal tank (or air blower).
During the installation of the cutting head, dust or dirt may accidentally enter the cutting head, contaminate the optical
lens, and affect its normal functions. To prevent dust or dirt from entering the cutting head, please refer to the following
methods for the installation of the cutting head:
Cutting head
clean workbench
Flashlight Ethanol Dust-free cotton swab
dust-free cloth Compressed air dust removal tank
Purification Kit
Notice:
The above operations can only be carried out by personnel who have received
appropriate training and have professional knowledge.
In order to ensure the normal operation of the laser device and the safety of operators,
please be sure to follow the relevant operating instructions.

5.2 Specific operation process
5.2.1 Preparation of clean bench
Prepare the clean bench, start it up and ensure its functionality:
1. Check that the equipment is clean and qualified (checks the cleanliness of the dust particle counter ), and
confirm that the FFU purification unit is within the validity period (measure the average wind speed in the working area,
when the wind speed cannot reach 0.3m/s, the FFU purification unit must be replaced);
2. Check whether each switch is running normally, and check whether the fan is running normally;
3. It is strictly forbidden to install unnecessary items in the clean working area to ensure that the clean air flow is
not disturbed;
4. For clean workbenches that are newly installed or have not been used for a long time, please use a clean cloth
and anhydrous ethanol to wipe them clean before use;
During operation:
1. Turn on the power, and pull the glass sliding door of the clean workbench to the lowest position (leaving a gap
of about 10cm);
2. Start the fan, it is recommended to purify the clean table for about 30 minutes in advance;
3. Turn on the light source of the clean workbench.
5.2.2 The cutting head is placed in the clean workbench
Put the cutting head horizontally inside the clean workbench.
Clean table type: vertical
purification; cleanliness class: ISO
5, 100; average wind speed ≥
0.4m/s
Notice:
To prevent dust from contaminating the core area of the
cutting head, please ensure the integrity of the special
protective film/cap for the optical fiber interface before
plugging and unplugging the optical fiber.

5.2.3 Clean and wipe the fiber interface of the cutting head
Wipe the fiber interface of the cutting head with a clean cloth and anhydrous ethanol.
5.2.4 Check the laser fiber end face
Remove the protective cap of the laser fiber, and irradiate the end face of the fiber with a strong flashlight to observe
whether there is any pollution; if it is clean, you can directly insert the fiber;
5.2.5 Tear off the protective film/remove the protective cap
Remove the special protective cap/protective plug for the optical fiber interface on the cutting head.

5.2.6 Insert the laser fiber interface into the cutting head
Align the fiber optic plug with the red dot, insert it into the unlocked fiber optic port, and ensure that it is inserted as far
as it will go. Rotate the lock cap until it tightly locked.
5.2.7 Wrap and seal
After inserting the optical fiber, wrap and seal the interface between the optical fiber and the cutting head with tape.

5.2.8 Mount the cutting head on the backplane
The cutting head can be installed on the Z-axis backplane of the machine tool through four screws A, B, C, and D.
When fixing the cutting head on the machine, it must be ensured that the cutting head is locked and there is no obvious
movement.
Notice:
To achieve affective sealing, it is recommended to wrap the tape
at least three times for sealing.
