Installation
Installation must only be performed by competent personnel observing
all the applicable safety regulations. This also applies to any local
safety regulations and accident prevention regulations not mentioned
in these operating instructions.
4.1 Assembly and connections
The UM-X measurement analysis system is intended for wall mounting. It can only
be mounted and connected while it is open:
• Undo the four cover screws.
• Carefully remove the cover. It is still connected to the printed circuit board with
two ribbon cables.
• Unplug the connectors in order to be able to completely remove the cover.
• Now you can mount the measurement analysis system.
The measurement analysis system must be installed outside the
potentially explosive area. Sensors for the potentially explosive
atmosphere can be connected to the UM-Ex and UM-O Ex devices.
• Connect the cables for the auxiliary power and the filling level sensor to the
measurement analysis system after it has been mounted. An external
acknowledgement button and external control units can optionally be
connected.
See Section 4.2 "Pin assignment" in this Chapter.
Close the measurement analysis system again after mounting and connection of
all electrical cables.
• First, plug the wide ribbon cable back into its holder which has reverse polarity
protection.
• Now, connect the narrow ribbon cable back to the membrane keypad. Pay
particular attention here to the correct seating of the socket as this does not
have reverse polarity protection.
• Close the measurement analysis system using the four cover screws.
