6.2 Assembling the u-control station
WARNING
Explosion risk!
▶ Prior to starting work, make sure that
there is not a potentially explosive atmos-
phere!
WARNING
Dangerous contact voltage!
▶ All work on the u-control station must be
carried out with the power supply discon-
nected.
▶ Make sure that the place of installation
(switch cabinet etc.) has been discon -
nected from the power supply!
ATTENTION
The product can be destroyed by elec-
trostatic discharge!
The components in the u-control series can
be destroyed by electrostatic discharge.
▶ Please make sure that personnel and work
equipment are adequately earthed!
Please note that for failure-free operation the end
brackets delivered with the controller have to be
installed necessarily to achieve a permanent set
of the u-control station.
▶ On the left side of the installation site, place an end
bracket on the DIN rail with the exterior of the bracket
facing left and screw it down tightly (using a 3-mm
screwdriver).
Attaching the end bracket
When installing u-control products and u-remote
products, make sure that you listen for the double
click:
1. When snapping onto the DIN rail
2. When pushing together with the neighbouring
module.
The modules are in the correct position and the
connection is made only when both snapping
noises are heard.
ATTENTION
Improper installation may prevent
earthing!
The earthing of the controller and modules is
only ensured if the FE spring at the bottom is
in contact with the DIN rail.
▶ During installation, make sure that both
release levers on the controller and all
release levers on the modules are closed
before snapping onto the DIN rail.
