Fig. 22: Dismantling the circuit board.
Remove the smartboard upwards out of the rails.
Proceed as follows if the space is tight:
Loosen and remove the centre screw in the module hous-
ing
1
.
Turn the retaining bracket with rail
2
to the left.
Remove the smartboard
3
to the front.
Carry out the electrical wiring and install the smartboard.
Install the smartboard including the module housing in
the reverse order to dismantling them.
Important:
After completion of the electrical wiring, do not
push the cables through the motor guard close to the fan!
Observe these points in the following installation diagrams with KaControl:
Comply with the details on cable types and cabling with due consideration of VDE 0100.
Without *: NYM-J. The requisite number of wires, including PE conductor, is stated on the cable. Cross-sections are not
stated, as the cable length is involved in the calculation of the cross-section.
With *: J-Y(ST)Y 0.8mm. Lay separately from high voltage lines.
With **: Lay UNITRONIC BUS LD 0.22 mm² or similar separately from high voltage lines.
If other types of cables are used, they must be at least equivalent.
Length of Bus line from the KaController to unit 1: max. 30 m.
Maximum number of parallel units: 2 units. With a CAN bus card type 3260301 (see Accessories) needed for each unit
and a terminal resistor on the first and last unit, maximum 30 no.
Length of Bus line from unit 1 to unit 2 max. 30 m. With each unit, requisite CAN bus card type 3260301 (see Accessor-
ies), maximum 500 m.
Length of cable for room sensor and switching contact maximum 30 m, 1 mm², maximum 100 m
The terminals on the unit for the mains power supply are suitable for a maximum wire cross-section of 2.5 mm².
When using residual current circuit breakers, they need to be at least mixed frequency-sensitive (type F) for types 44xx5x
and 45xx56, and all current-sensitive (type B) for all other types. When the power supply to the unit is switched on,
pulsed charging currents of the capacitors in the integrated EMC filter can cause residual current safety devices to trip.
The electrical data needs to be respected when rating the in-situ mains power supply and fusing.
