1 Safety Warnings
This device is intended to be used as part of a safety system which may be used to protect personnel
and equipment from possible injury, damage, or loss.
As such it must be installed and wired according to these instructions and tested by suitably qualified
persons. No attempt may be made to tamper with the parts, open them, or use them outside of the
parameters contained herein.
The units are only designed to be fixed to surfaces using their inbuilt fixing holes. They must not
come into contact with each other or any other moving part when in use. The parts should never be
subject to impact or mechanical strain.
Safety switches should never be defeated or bypassed. It is imperative that all steps are taken to
ensure that any spare actuators are made unavailable, such that they cannot be used to defeat the
switch or reduce the protection offered by the system in any way.
2 Concept
The Miniature LED Sign Power and Switch Unit is intended to be used in conjunction with Lasermet’s
Miniature LED Signs. The Power and Switch Unit accepts a mains input and provides the correct
voltage to illuminate the sign. A switch on the unit allows the sign to be turned on and off in the case
of one-way signs and switched between off and the two indications in the case of two-way
red/green signs. The unit is usually sited at a convenient position for users to operate the switch and
can be wall or desk mounted.
The unit is able to power one Lasermet Miniature LED Sign.
Lasermet provides a full range of laser interlock equipment including control systems, interlock
switches, illuminated warning signs, laser shutters, door locks, external power supplies etc. which
can be connected to provide a complete laser interlock system. Full support, design and installation
is available from Lasermet, please contact us for any queries. Contact details are given at the end of
this manual.

3 Installation
The Power and Switch Unit is capable of operating one Lasermet LED Miniature Sign.
The unit is designed to be permanently attached to a wall or other fixed vertical surface. It should be
mounted in a convenient position for use and wiring. Normally it is wall-mounted on the inside of
the entry door of the controlled area.
During installation, fixed wired connections will need to be made from the Power and Switch Unit to
the incoming mains supply and the Miniature LED Sign. A Ø20mm conduit hole is provided and
allowance should be made for the installation of electrical conduit to make entry to the bottom of
the unit.
Refer to Figure 1 for details of the fixing holes and cable entry. Secure the unit to the wall using
suitable screws and wall plugs according to the type of wall.
Remove the plug from the bottom of the unit and attach the conduit.

4 Wiring
The unit is factory configured for 110Vac input for US customers and 220-240Vac for UK and
European customers.
The mains supply to the unit should incorporate a double pole isolator and overcurrent protection of
a 3A or 5A circuit breaker or a 3A fuse. An earth connection is not required. Electrical installation
must comply with local wiring regulations.
The incoming and outgoing wires share a common conduit, therefore the cable to the sign should
have an insulation rating which exceeds the mains supply voltage. Unscreened 7/0.2mm cable
approved to DEF STAN 61.12 parts 4 and 5 is recommended. One-way signs require two-core cable,
Red/Green signs require three cores.
A two-way terminal block is provided for the incoming mains supply.
A three-way terminal block is provided for connection to the sign. In the case of PSLEDS-1W, the
GN+ terminal is inoperative and is unused.
The connections for the One-Way Warning Sign with PS-LEDS-1W are shown in figure 2 on the next
page.
The connections for the Two-Way Red/Green Warning Sign with PS-LEDS-RG are shown in figure 3.
