750 XTR Series
Use an end stop for vertical installation!
For vertical installation, always mount an end stop below the node to prevent it from slip-
ping off.

5.2.6 DIN-Rail Characteristics

All components of the system can be snapped directly onto a DIN-rail per EN 60715
(TS 35, DIN-rail 35).
WAGO supplies standards-compliant DIN-rails that are ideal for use with the WAGO I/O
System.
If you want to use non-WAGO DIN-rails, WAGO GmbH & Co. KG must perform a techni-
cal inspection and approve them.
DIN-rails have different mechanical and electrical characteristics. For optimal setup of the
system on a DIN-rail, the following boundary conditions must be met:
• The material must have high corrosion resistance.
• Most of the components must have a discharge contact with the DIN-rail to discharge
electromagnetic interference. In order to prevent corrosion, this tin-plated DIN-rail must
not form a galvanic element that is capable of generating a differential voltage of more
than 0.5 V (saline solution of 0.3 % at 20 °C/68 °F).
• The DIN-rail must provide optimal support for the EMC measures integrated into the
system and the shielding via the I/O module connections.
• Select a sufficiently stable DIN-rail and, if applicable, use multiple mounting points (ev-
ery 20 cm) for the DIN-rail to prevent bending and twisting (torsion).
• In order to ensure that the components are held securely in place, the DIN-rail geome-
try must not be altered. The DIN-rail must not be squeezed or bent, especially when
shortening and installing it.
• The snap-in mounting foot of the components extends into the profile of the DIN-rail.
For 7.5 mm high DIN-rails, mounting points (screw connections) under the node must
be countersunk in the DIN-rail (countersunk screws or blind rivets).
• The medal springs on the bottom of the housing must have a low-impedance contact
with the DIN-rail (wide contact surface is possible).
WAGO DIN-rails meet the electrical and mechanical requirements.
