• Qualified service and maintenance personnel
Obey the following safety rules:
2.1 General Safety Rules
• This documentation is part of the product. Therefore, retain the documentation during
the entire service life of the product. Pass on the documentation to any subsequent
user of the product. In addition, ensure that any supplement to this documentation is
included, if necessary.
• The product must only be installed and put into operation by qualified electrical special-
ists per EN 50110‑1/-2 and IEC 60364.
• Comply with the laws, standards, guidelines, local regulations and accepted technol-
ogy standards and practices applicable at the time of installation.
2.2 Electrical Safety
• High voltage can cause electric shock or burns! Disconnect all power sources from the
product before performing any installation, repair or maintenance.
• Make sure the product does not carry any voltage before starting work.
Power Supply
• Connecting impermissible current or frequency values may destroy the product.
• Provide suitable disconnect and overcurrent protection on the system side. The protec-
tion device must be located near the product where it can be operated. The OFF posi-
tion must be clearly marked on the protection device.
Ground / Protection / Overcurrent Protection
• When handling the product, please ensure that environmental factors (personnel, work
space and packaging) are properly equalized. Do not touch any conducting parts.
• Establish sufficient grounding. Make sure there is a flawless electrical connection be-
tween the DIN-rail and frame / additional enclosure.
• Only operate the product when the ground conductor is connected.
• Protect the product with an appropriate overcurrent protection device.

2787-2147 Security
Product manual | Version: 1.1.0 11
Power Supply Pro 2
• Only clamp one conductor to each connection terminal. If several conductors must be
clamped, wire them using an upstream wiring assembly (e.g., WAGO Through Termi-
nal Blocks).
• Use appropriate strain relief.
2.3 Mechanical Safety
• As the installer of the system, you are responsible for ensuring the necessary touch-
proof protection. Follow the installation guidelines for the specific application.
• The surrounding air temperature for operation indicated in the technical data applies to
the nominal mounting position. Different mounting positions may affect the permissible
surrounding air temperature for operation.
• Cooling of the product must not be impaired. Ensure air can flow freely and that the

• Before startup, please check the product for any damage that may have occurred dur-
ing shipping. Do not put the product into operation in the event of mechanical damage.
• Do not open the product housing.
• Replace any defective or damaged devices.
• The product is an open-type device and is designed for installation in an additional en-
closure, which supplies the following safety aspects:
– Restrict access to authorized personnel and may only be opened with tools.
– Ensure the required pollution degree in the vicinity of the system.
– Offer adequate protection against direct or indirect contact.
– Offer adequate protection against UV irradiation.
– Prevent fire from spreading outside of the enclosure.
– Guarantee mechanical stability.
2.4 Thermal Safety
• The surface of the housing heats up during operation. Under special conditions (e.g., in
the event of a fault or increased surrounding air temperature), touching the product
may cause burns. Allow the product to cool down before touching it.
• The temperature inside the additional enclosure must not exceed the surrounding air
temperature permitted for the mounted product.

3.1 Introduction
The 2787 Series WAGO Power Supplies Pro 2 are compact switched-mode
Power supplies with a wide range of uses. The Power supplies can be fitted on a DIN-rail.
The Power supplies can be configured directly via buttons on the product or via the inte-
grated communication interface. For this purpose, the connection is established either via
the WAGO USB configuration cable or via an attached communication module. It is also
possible to record and evaluate various output parameters via the WAGO Interface Con-
figuration software, which is available separately.
The pluggable connection technology uses WAGO pluggable connectors. These allow
pre-wiring for quicker installation, as well as quicker and easier product replacement.
LEDs indicate various diagnostic messages (see section 8Indicators [}16]).

3.8 Communication interface
The communication interface is covered with a cap. Remove this cap to use the commu-
nication interface.
!
NOTICE
Avoid destruction of the product by electrostatic discharge!
The contacts of the communication interface are very sensitive to electrostatic discharge
(ESD). If the contacts remain open continuously, the product can be destroyed!
• Remove the cap only when using the communication interface!
Note
Save cap!
Save the cap so you can re-close the communication interface after use. This prevents
contamination or foreign matter from getting into the open communication interface.
You can communicate with the product through the communication interface. The follow-

The WAGO USB Communication Cable is intended exclusively for parameterization and
is not designed for continuous communication. Use a corresponding communication mod-
ule for continuous communication!
If you use a communication module, the corresponding communication module is de-
scribed in the & Product Manual.
To connect to a PC with the WAGO USB Communication Cable, perform the following
steps:
1. Remove the cap.
2. Connect the USB connector of the WAGO USB Communication Cable to your PC.
3. Carefully insert the plug for the communication interface straight into the communi-
cation interface in such a way that the keying tab fits into the lower recess.
ð The plug is seated correctly once it has been inserted into the interface up to the
stop. However, since the contours of the housing and plug differ, the plug does
not sit completely flush with the surface of the housing.
You can now connect to your product with the WAGO Interface Configuration software
and configure it (see section 8Configuration [}37]).
