Safety
Information to the user
The NC4 set-up tool (Renishaw part no. A-4114-8000, sold separately) is supplied with non-rechargeable
lithium metal batteries. Refer to the battery manufacturer’s literature for specic battery operating, safety
and disposal guidelines.
• Do not attempt to recharge the batteries.
• Replace the batteries only with the specied type.
• Do not mix new and used batteries in the product.
• Do not mix different types or brands of batteries in the product.
• Ensure that all batteries are inserted with the correct polarity in accordance with the instructions in
this manual and indicated on the product.
• Do not store the batteries in direct sunlight.
• Do not expose the batteries to water.
• Do not expose the batteries to heat or dispose of the batteries in a re.
• Avoid forced discharge of the batteries.
• Do not short circuit the batteries.
• Do not disassemble, apply excessive pressure, pierce, deform or subject the batteries to impact.
• Do not swallow the batteries.
• Keep the batteries out of the reach of children.
• If the batteries are swollen or damaged do not use them in the product and exercise caution when
handling them.
• Dispose of waste batteries in accordance with your local environmental and safety laws.
Ensure that you comply with international and national battery transport regulations when transporting the
batteries or this product with the batteries inserted. Lithium metal batteries are classied as dangerous
goods for transportation and require labelling and packaging in accordance with the dangerous goods
regulations before being offered for transportation. To reduce the risk of shipment delays, should you need
to return this product to Renishaw for any reason, do not return any batteries.
In all applications involving the use of machine tools, eye protection is recommended.

Information to the machine supplier / installer
It is the machine supplier’s responsibility to ensure that the user is made aware of any hazards involved in
operation, including those mentioned in Renishaw product literature, and to ensure that adequate guards
and safety interlocks are provided.
If the NC4+ Blue unit fails, the output signal may falsely indicate beam not blocked. Do not rely on signals
from the NC4+ Blue unit to halt the movement of the machine.
Information to the equipment installer
All Renishaw equipment is designed to comply with the relevant UK, EU and FCC regulatory requirements.
It is the responsibility of the equipment installer to ensure that the following guidelines are adhered to, in
order for the product to function in accordance with these regulations:
• any interface MUST be installed in a position away from any potential sources of electrical noise (for
example, power transformers, servo drives);
• all 0 V/ground connections should be connected to the machine “star point” (the “star point” is a single
point return for all equipment ground and screen cables). This is very important and failure to adhere
to this can cause a potential difference between grounds;
• all screens must be connected as outlined in the user instructions;
• cables must not be routed alongside high current sources (for example, motor power supply cables),
or be near high-speed data lines;
• cable lengths should always be kept to a minimum.
Equipment operation
If this equipment is used in a manner not specied by the manufacturer, the protection provided by the
equipment may be impaired.

Warnings
Use of controls or adjustments or performance of procedures other than those specied within this
publication may result in hazardous radiation exposure.
Switch off the power supply before carrying out maintenance on the NC4+ Blue system.
When using the NC4+ Blue system, basic safety precautions must always be followed to reduce the risk of
re, electric shock and personal injury, including the following:
• Read all instructions before operating this product.
• The device must only be installed and used by competent, trained personnel.
• Use eye protection to protect against mechanical hazards, coolant and swarf.
• Avoid inhalation of coolant vapour from the machine tool.
• Do not block the air exiting from the transmitter, receiver or air blast apertures.
• The sound power emitted by the air blast equipment can range from 70.3 dB at 0.3 MPa (43.51 psi)
to 78.2 dB at 0.6 MPa (87.02 psi). It is the responsibility of the integrator to ensure a suitable noise
assessment is performed when the equipment is put into use.
• Prevent direct exposure of the eyes to the laser beam.
• Ensure that the beam is not reected into the eyes via any reective surface.
CAUTION – LASER SAFETY
The laser used in the Renishaw NC4+ Blue non-contact tool setting system emits visible blue light at a
wavelength of 405 nm and has a power output of less than 1 mW.
The NC4+ Blue unit is classied as a Class 2 laser product as dened by BS EN 60825-1:2014.
Complies with 21 CFR 1040.10 and 1040.11 except for conformance with IEC 60825-1 Ed. 3., as
described in Laser Notice No. 56, dated May 8, 2019.
BS EN 60825-1:2014 directs to attach a laser warning label and explanatory label.
A warning label and explanatory label are permanently xed to each side of the transmitter (Tx) housing
(see page 1-6, “Laser safety and warning labels”, for further information). An adhesive warning label is
also provided. Renishaw advise attaching this label to the outside of the machine tool, in a visible location.

to the laser beam.
CAUTION SYMBOL
The caution symbol on the access panel denotes
the following:
CAUTION – Class 3R Laser radiation when
open. Avoid direct eye exposure.
