Chapter 1 Overview
Chapter 1 Overview
1.1 Introduction
The LSS10 Laser Safety Sign Lightbox provides a clear indication that a laser system
is in use by illuminating the laser safety sign (sold sepa rately) that states the
appropriate warning message and laser classification. The lightbox accepts any one
of the LSS10 se ries Laser Safety Signs available from our website. Signs can be
quickly interchanged making it easy to update signage to meet your cha nging laser
set up requirements.
The box operates at 100 to 240 VAC, (i.e. USA and EU regions) and has two safety
interlock options (internal and external - see Section 4.2.) th at prevent the use of
interlock-equipped laser systems unless the safety light is turned on. The external
interlock socket accepts a 2.5 mm phono jack (supplied).
The lightbox is permanently fixed to a wal l via the moun ting slots in the rear panel.
Two sets of slots are available to allow positioning of the controls for left or right
handed operation. A convenient line cord latch preven ts the AC line cord from
disengaging from the unit.
Illumination is controlled by turning a knob on the right hand side of the unit, allowing
the brightness to be adjusted to suit th e specific location of use. An internal jumper
can be activated which bypasses the external control, thereby making the brightness
tamperproof. Illumination is then controlled by a set of switches on the circuitboard -
see Section 4.5.

Chapter 2 Safety
2.1 Safety Information
For the continuing safety of the operators of this equipment, and the protection of the
equipment itself, the operator should take note of the Warnings, Cautions and Notes
throughout this handbook and, where visible, on the product itself.
The following safety symbo ls may be u sed throughout the h andbook and on the
equipment itself.
2.2 General Warnings
Warning: Risk of Electrical Shock
Given when there is a risk of injury from electrical shock.
Warning
Given when there is a risk of injury to users.
Caution
Given when there is a risk of damage to the product.
Note
Clarification of an instruction or additional information.
Warning
If this equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired. In particular, excessive
moisture may impair operation.
Spillage of fluid, such as sample solutions, should be avoided.
If spillage does occur, disconnect the power then clean up immediately using
absorbant tissue. Do not allow spilled fluid to enter the internal mechanism.
The equipment is for indoor use only.
The equipment is not designed for use in an explosive atmosphere.

Chapter 2 Safety
Warning: Risk of Electrical Shock
The light box is powered by mains voltages. This is hazardous and can cause
serious injury. Appropriate care should be taken when using this device.
Persons using the device must understand the hazards associated with using
high voltages and the steps necessary to avoid risk of e lectrical shock.
Particular care should be observed when adjusting or operating the unit via the
internal PCB controls.

Chapter 3 Installation
3.1 Mechanical Installation
The lightbox can be permanently fixed to a wall, via the four mounting holes in the rear
panel - see the dra wings available from www.thorlabs.com for details and
dimensions.
Furthermore, several metalwork knockouts are provided for grommets (supplied) and
cables when hard wiring the unit into an electrical system.
3.2 Electrical Connections
The unit is connected to the mai ns power using the cable supplied, via the IEC 14
connector on the right hand side - see Fig. 3.1.
Caution
Screws or fittings to attach the unit to the wall are not included. Always choose
M4 (8-32) screws and fittings which are suitable for use in your wall and have
enough holding power. Do not use screws with cou ntersunk heads. If you are
uncertain, contact a specialised installer.
Note
The default configuration and labelling is for right-handed use, however the mounting
holes allow the unit to be mounted for left hand use.
Caution
The unit must be fixed securely to the wall before using the internal wiring option.
Do not use the internal wiring option when the unit is fixed via the keyed slots in
the rear panel.
Warning
The unit uses mains voltages. This is hazardous and can cause serious injury.
The unit must be installed only by suitably trained and qualified personnel who
understand the ha zards associated with using high voltages and the steps
necessary to minimize the risk of electrical shock.
Warning
If using a power cord other than that supplied, ensure that the cord is at least
equivalently rated (see Se ction 5.1. fo r power cord ratings) an d does not
exceed 3m in length.
Use only power cords with a factory supplied moulded IEC C13 connector. Do
not use cords fitted with rewirable connectors.
Rev A Nov 2017 Page 5
Chapter 3 Installation
A convenient line cord latch prevents the power cord disengaging from the unit. The
cord latch is supplied loose and should be fitted before the lightbox is used.
Fig. 3.1 Power supply connection panel
Although the unit is supplied preset for external power connections, power can be
hard wired to the internal PCB as follows:
1) Ensure that the unit is disconnected from mains power.
2) Using a PZ1 screwdriver or other suitable tool, remove the six M3 PoziDriv screws
securing the front panel.
Cautions for Hard Wiring the Unit
The unit should be hard wired only when it is permanently attached to the wall.
Only use 3-core (0.75 to 1.5 mm2) 218/318 cable to EN 50525-2-11 to hard wire
the unit.
Grommets with a flammability rating of UL94-V-1 or better must be used at the
cable exit points. Suitable grommets are supplied.
In order to prevent accidental disconnection of cables, ensure that the strain
relief clamp provided is used. The clamp is fitted with two M3 x 6mm screws for
use with standard cable diameters. Two M3 x 8 mm screws are also supplied
for use with larger diameter cables.
A switch or circuit breaker must be incl uded in the installation. It must be
conveniently located and easily reached, and must be clearly marked as the
disconnecting device for the equipment.

3) Pull to the left and forward to remove as shown in Fig. 3.2 over the page. Keep the
cover supported until the internal electrical connection is disconnected at the next
step.

4) Unclip the connection to the LED circuit CON4 - see Fig. 3.3 then remove the panel.
5) Ensure mains power is disconnected, then move the INT /EXT jumpers at the
bottom of the PCB to the INT position as shown below.

6) Make connections using connector CON2 as shown in
Fig. 3.3
. Use the cable
knock-outs, grommets (supplied) and strain relief clamps provided to ensure that
the cable is adequately supported and restrained - see Fig. 3.4.

7) If using an internal safety interlock, perform the procedure detailed in Section 4.2.
8) Re-connect the LED circuit at CON4.
9) Refit the front panel.
10) To change from hard-wired power to using the panel connections, isolate the unit
from the mains supply, then reverse the steps previously described.

Chapter 4 Operation
4.1 Control and Connection Overview
The controls are located on the side panel above the power supply connections as
shown below.
Fig. 4.1 Controls overview
BRIGHTNESS - Used to control the light intensity of the lightbox (when the external
controls (see Section 4.5.) are enabled).
INTLK - For use in laser safety applications - see Section 4.2.
POWER - Used to switch the unit on and off.
Caution
The ON/OFF switch mentioned above removes power from the internal lighting
circuit. It does not remove power from the unit itself.
