1 Safety Information
Do not work when devices are energized!
High voltage can cause electric shock or burns.
Switch off all power to the device prior to performing any installation, repair or main
-
tenance work.
Live parts are likely to be touched!
The party setting up the device is responsible for providing appropriate touch guards.
The installation regulations must be observed for each individual application.
Hot surface!
The surface of the housing can become hot during operation. Under high ambient
temperatures, there is a danger of burns when the device is touched. If the device was
operated at high ambient temperatures, allow it to cool off before touching it!
Select conductor cross sections as required for current load!
In the event of a fault, the output current of a power supply can be up to 1.5 × I
OUT
.
Only use conductor cross sections designed for this current load.
i
Only valid in conjunction with the device‘s manual!
These instructions are only applicable in conjunction with the device‘s manual!
You will find this manual on the Internet at www.wago.com/
<OrderNumber>
.
In addition, please observe the information provided on the device’s housing.
Please especially observe the following:
• The device described in these instructions shall only be installed by a qualified electrician
according to both EN 501101/2 and IEC 60364.
• Before startup, check the device for any damage that may have occurred during shipping.
The device shall not be put into operation in the event of mechanical damage.
• Observe the applicable laws, standards and regulations.
• Observe the current, accepted technology standards and practices at the time of installation.
• Only install this device in dry indoor rooms.
• Do not install the devices on or in the vicinity of easily flammable materials.
• Only use this device in a controlled enviroment.
• The device is an open system. The device must be installed in a suitable electrical and fire
enclosure. This enclosure must:
- guarantee that the max. permissible pollution degree is not exceeded
offer adequate protection against direct or accidental contact,
guarantee mechanical stability over the entire operating temperature range
• Ensure proper handling to protect device during shipping and handling. Particularly during
transport and handling, ensure that no parts are bent and that electrical spacing remains
constant.
• Keep sufficient distance from adjacent components to avoid interfering with the cooling!
• The operator must provide a mains isolator in the device supply line. The
OFF
position must
be clearly marked on this isolator. The isolator must be located near the device where it can be
operated.
This product may only be used as described in this note and in the complete instructions. Use
other than this may represent a risk to safe, intended use and will nullify the warranty or guarantee.
WAGO Kontakttechnik GmbH & Co. KG is not liable for damage resulting from nonintended or
improper use.

4 Mounting/Removal
Avoid electrostatic discharge!
The devices are equipped with electronic components that you may destroy by
electrostatic discharge when you touch. Please observe the safety precautions against
electrostatic discharge in accordance with EN 6134051/3
.
Pay attention while hand
-
ling the devices to good grounding of the environment (persons, job and packing).
Do not cover the ventilation openings!
To ensure adequate air circulation, the ventilation openings must be kept clear.
Keep at least 50 mm from the ventilation openings to adjacent surfaces.
4.1 Mounting Positions
• As nominal mounting position applies (see also presentation under “View”):
Front (d), ventilation openings (a) top and bottom.
• Other mounting positions are permitted. In this case, observe the modified conditions of use
(see table “Ambient Conditions”).
• The device may be operated directly next to other components.

4.2.1 Installation to the DIN Rail
Install the device by snapping it into the DIN rail according to EN 60715 (see figure “Mounting”):
1. Place the device with its DIN rail guide on the top edge of the DIN rail.
2. Press the device onto the DINrail [A] while simultaneously pulling on the latch (g) [B] until it
locks into place.
3. To ensure secure fastening on the DIN rail, fit end clips on either side of the device (e.g., Order
No.
249-197
).
4.2.2 Removal from the DIN Rail
1. To remove (see Figure “Removal”), pull down the latch (g) [C].
Use a screwdriver or an operating tool for this.
2. Tilt the device forward [D] and detach it from the DIN rail.
5 Wiring
You can use the push-buttons of the corresponding clamping unit to connect or disconnect the
conductors.
To open the clamping unit via the respective pushbutton, use an operating tool or a screwdriver.
All terminals use pushin technology for toolless wiring by plugging them in directly. Please note:
• Finestranded conductors must have a ferrule (insulated or uninsulated). Corresponding
conductor sizes are found in the “Wiring – Dimensions” table.
• You can plug solid conductors in directly even without a ferrule.
