2. Safety information
IMPORTANT!
READ BEFORE INSTALLATION!
The Universal Power Supply (UPS) was developed
and manufactured using state-of-the-art systems and
technologies.
To ensure safe conditions:
Read all enclosed instructions and information
Follow the instructions given in this manual carefully
Observe all warnings included in the documentation
and attached to the UPS
Keep the instruction manual on site
When the UPS and a MiniMax or cegard/Mini light curtain
are used as a replacement for mechanical safety edges,
it is the responsibility of the installer to ensure that on
completion, the installation complies with all the relevant
state codes, local codes and regulations that pertain to
infrared and photoelectric door protection devices!
The UPS should only be installed by authorized and fully
trained personnel!
In Canada, particular attention should be given to clauses
2.13.5.1 and 2.13.5.2 CAN/CSA-B44-B89!
In the USA, all connections requiring 42 Volts or greater
must be wired through Greenfield tubing and fittings.
Disconnect power before opening the control unit to
prevent electrical shock. Do not remove any inside covers
or fuse caps.
2.1 Non-intended use
The UPS must not be used for:
• Protection of dangerous machines
• Equipment in explosive atmospheres
• Equipment in radioactive environments
Use only specific and approved safety devices for such
applications, otherwise serious injury or death or damage
to property may occur!

4. Introduction
The Universal Power Supply (UPS) offers a wide ranging
power supply for MiniMax or cegard/Mini light curtains.
A voltage range from 20 to 265 VAC or a range from 20
to 375 VDC can be converted to 24V DC. If DC voltage
is used, the polarity of terminals P and N is irrelevant.
The output of the light curtain will be converted into a
potential-free relay contact.
For details about MiniMax or cegard/Mini light curtains,
please refer to the corresponding installation and
instruction manual.
The UPS consists of the controller and the required plugs
to connect the power supply, the outputs and the light
curtain.
The UPS is generally mounted on the top of the elevator
car or in the car-operating panel and acts as power supply
for 24 V light curtains such as MiniMax or cegard/Mini.
4.1 Features of the UPS
• Electrical isolation between high and low power side
• Potential-free relay output
• Robust housing with an IP54 enclosure rating
• Clear wiring due to separate clamps for emitter and
receiver
• On/Off buzzer function
• EMC filter ensures trouble-free operation
5. Installation
The installation should be done in the following sequence:
1. Switch main power off and mark clearly that this
elevator is out of service.
2. Install the light curtain emitter, receiver and cables.
3. Mount the UPS.
4. Carry out the electrical installation.
5. Power-up and test for proper function.
5.1 Switch OFF main power
For your own safety, turn the power off before you start
working on the elevator! Clearly mark that this elevator
is out of service.
5.2 Installation of light curtain
The emitter and the receiver edges can be mounted either
to the door wings, to the door wing and the slam post, or
to a frame that is attached to the car. For details, please
refer to the corresponding installation and operation
manual.
Important:
Please note that objects smaller than the sensor spacing
may not be detected!
It is very important to pay close attention to a proper
cable installation to ensure the highest possible reliability
and lifespan of the light curtain. A properly installed cable
will withstand more than 20 million door movements,
while a poorly installed cable will break after less than
100,000 door movements.
5.3 Installation of the UPS
The UPS unit can be mounted horizontally or vertically with
four screws near the door drive.

NOTICE
The PCB is sensitive to electrostatic discharge
and must be handled with care to prevent
callbacks. Use anti-static procedures when
handling these boards.
For the USA and Canada:

3 From T&B or other UL/CSA approved manufacturer
Connect all wiring with more than 42 V
through a Greenfield fitting.
Disconnect power before opening
the UPS to prevent electrical shock.
Otherwise serious injury or death may
occur!

6. Electrical connection
Power supply
N : AC neutral, plus or minus for DC
P : AC hot, plus or minus for DC
: Protective ground
Wire the light curtain to the Universal Power Supply
• The receiver connector (3-pin WAGO connector) must be plugged into the 3-pin WAGO plug.
• The emitter connector (2-pin WAGO connector) must be plugged into the 2-pin WAGO plug.
Follow the wiring diagram (Figure 3) to connect the door drive to the relay output. Only if the relay is connected
as shown in the diagram below, will the whole unit work as a “fail safe”4protection device.
Figure 3: Wiring of the UPS with a light curtain
4 Fail Safe Operation:
Due to the nature of door system designs, (which as complete systems are not fail safe), doors can close even with an obstacle present in
extremely rare conditions. Therefore, there must be, by code, other safety means to prevent passengers from being hurt by the elevator
doors. These dangerous situations should and can be detected by the elevator control, which should, in such a case, take the elevator out
of service.
This device (as well as all other door protection systems on the market) cannot – by its nature – provide absolute safety for elevator
passengers passing through the doorway. It must not be used as the final fail-safe device of the door mechanism. This ultimate safety
function has to be provided by a fail safe force and kinetic energy limiter.
