Installation instructions V2.5
MICO 4.6 Art.-No.: 9000-41034-0100600
Safety instructions:
Warning: This equipment is only suitable for the operation on +24V DC (protection low voltage). The direct
connection of this equipment may cause death, severe bodily injuries and considerable property
damage.Only competent and qualified personnel may work on this equipment or in its proximity. The perfect
and safe operation of this equipment requires the appropriate transportation, professional storage, erection
and installation.
Attention:
- Only trained personnel shall open this equipment. Electrostatic sensitive device (ESD).
- During service work when manually disconnecting MICO, the operating company shall ensure that the
system is protected against unintended reconnection (according to the currently applicable provisions BGV
A3 (Trade Association Ordinance) or. EN 50110-1).
- Parallel switching of multiple load branches for increase of power is not permitted.
- Series connection of several MICO module to produce selective switch-off-characteristic is
not allowed.
- A generated voltage at output is not allowed to be durably higher than the input voltage.
Notice: The GND connection of the equipment merely serves to supply the internal electronics. The 0
voltage of the consumer shall be conducted directly to the power supply through separate lines.
The conductor cross-sections and line lengths must be adapted to the adjusted current range.
Recommendation: - Adjust the current range only if the channel is disconnected (red LED).
- Lay GND wire as near and parallel as possible to the 24V lines.
Installation
: For the installation the pertinent DIN/VDE regulations or country-specific rules must be
complied with. Assemble on support bar TH 35 pursuant to EN 60715. Due to operation-related heating the
equipment must be assembled vertically so that the input terminals are on top. A free space of 30 mm above
and below the equipment should be complied with. The connection of the supply voltage (24V DC) must be
performed in accordance with VDE 100 and VDE 0160 and shall only be connected to a power supply with
"safe separation" (SELV/PELV) corresponding to EN 60950-1 or 61558-2-6.
Condition at delivery: - Minimum current range of
each channel
- Channel disconnected
Accessories: - Bridging set: (see bridging set) / - Designation labels: Art.No.: 996067
ON-Restart inputs: The Re-start – input is provided in double; it provides the user with the possibility of
reconnecting load circuits disconnected by excess current by placing a defined signal at the input, e.g. 0V...
5V for "OFF" min. 1s long and 10V - 30V for "ON" min. 20ms long. This does not apply to manually
disconnected channels. They may only be activated through the button (2) at the module.
Summation message:
The summary output message is motivated by a potential-free message output
(terminals 13 and 14); it opens as soon as a channel has been disconnected or short-circuit released by
overload. The message output is capable of switching 30 VAC/DC at 100mA and is suitable to drive SPS
inputs.
