1.1 Safety

MLC8xxx / page 1

1 General description of the multi LD-controller MLC8xxx

1.1 Safety

Attention 

All statements regarding safety of operation and technical data in

this instruction manual will only apply when the unit is operated

correctly.

Before applying power to your PRO8000 (-4) / PRO800 system, make

sure that the protective conductor of the 3 conductor mains power

cord is correctly connected to the protective earth contact of the

socket outlet!

Improper grounding can cause electric shock with damages to your

health or even death!

Modules may only be installed or removed with the mainframe

switched off.

All modules must be fixed with all screws provided for this purpose.

Modules of the 8000 series must only be operated in the mainframe

PRO8000, PRO8000-4 or PRO800.

All modules must only be operated with duly shielded connection

cables.

Only with written consent from Thorlabs may changes to single

components be carried out or components not supplied by Thorlabs

be used.

This precision device is only dispatchable if duly packed into the

complete original packaging including the plastic form parts. If

necessary, ask for a replacement package.

1.1 Safety

MLC8xxx / page 2

Attention 

Semiconductor laser modules can deliver up to several 100mW of

(maybe) invisible laser radiation!

When operated incorrectly, this can cause severe damage to your

eyes and health!

Be sure to pay strict attention to the safety recommendations of the

appropriate laser safety class!

This laser safety class is marked on your PRO8000 (-4) / PRO800

plug-in module or on your external laser source used.

Attention 

Mobile telephones, handy phones or other radio transmitters are not

to be used within the range of three meters of this unit since the

electromagnetic field intensity may then exceed the maximum

allowed disturbance values according to EN 50 082-1.

1.2 Warranty

MLC8xxx / page 3

1.2 Warranty

Thorlabs GmbH warrants material and production of the MLC8xxx modules for a

period of 24 months starting with the date of shipment. During this warranty period

Thorlabs GmbH will see to defaults by repair or by exchange if these are entitled to

warranty.

For warranty repairs or service the unit must be sent back to Thorlabs GmbH

(Germany)or to a place determined by Thorlabs GmbH. The customer will carry the

shipping costs to Thorlabs GmbH, in case of warranty repairs Thorlabs GmbH will

carry the shipping costs back to the customer.

If no warranty repair is applicable the customer also has to carry the costs for back

shipment.

In case of shipment from outside EU duties, taxes etc. which should arise have to be

carried by the customer.

Thorlabs GmbH warrants the hard- and software determined by Thorlabs GmbH for

this unit to operate fault-free provided that they are handled according to our

requirements. However, Thorlabs GmbH does not warrant a faulty free and

uninterrupted operation of the unit, of the soft- or firmware for special applications nor

this instruction manual to be error free. Thorlabs GmbH is not liable for consequential

damages.

Restriction of warranty

The warranty mentioned before does not cover errors and defects being the result of

improper treatment, software or interface not supplied by us, modification, misuse or

operation outside the defined ambient conditions (refer to the PRO8000(-4) /

PRO800 mainframe operation manual) stated by us or unauthorized maintenance.

Further claims will not be consented to and will not be acknowledged. Thorlabs

GmbH does explicitly not warrant the usability or the economical use for certain

cases of application.

Thorlabs GmbH reserves the right to change this instruction manual or the technical

data of the described unit at any time.
