Floor loading capacity
The weights of the units require a minimum floor loading capacity. However, since these weights do not act upon the entire support surface but at points on the support surface, these support points must have adequate load bearing capacity. The individual weights can be obtained from the tables. A base is available as optional equipment.

NOTE For the water cooling option the weights of the hood and the cooling aggregate should be added to the respective system. For the filter cabinet option the weights shown in the last table added to the respective system.
In the case of the mains/load cabinets and the cooling cabinets, the weights of the individual system components act on the feet and in the case of the converter cabinet on the floor rails. For all systems the compressive loads per unit area under the support points are shown in the table below.

The floor loading capacity is an important factor in the overall strength of the supporting surface. It specifies the ratio between the weight of the unit and the installation area and is shown in the following table for all sizes of unit.

Openings are provided in the roof and bottom of the AC input and load cabinets for cable entries and outlets.
NOTE The dimensions of the cable entries in the AC input and load cabinets are shown on the drawings Fig. 1 - Fig. 9.
The connecting terminals are located at the following points: ! UB-SF 180 – UB-SF 625:
Mains 1 lower and upper part at the back row left side
Outgoing feeder lower and upper part at the back row right side ! UB-SF 1000
Mains 1 in centre and bottom of AC input cabinet Outgoing feeder in bottom of load cabinet
All unused cable entries should remain closed to prevent the ingress of foreign objects. The used openings should be sealed with suitable materials.
IMPORTANT The cable entries should be sealed on completion of the electrical installation to prevent bypass air entering the system.
Attaching the connecting cables
The cables should be connected to the brackets of the respective terminal bars with bolts, nuts and two plain washers.
IMPORTANT Please note that in aluminium-copper connections the two metals form an electrochemical element under the influence of an electrolyte (e.g. moisture), which results in the aluminium being dissolved. If an aluminium-copper bond if formed when the UNIBLOCK is connected up, suitable corrosion protection measures must be taken at the connecting point.
Bolt sizes:
! M12 x 35 property class 8.8
Bolt tightening torque:
! UB-SF 180 – UB-SF 1000: 60 Nm
All cables should be fitted with DIN 46 234 cable lugs.
IMPORTANT Please ensure that the phase of AC connections are correct since incorrect connections can cause damage to the system. (Direction of rotation of MG-set: counter clockwise, viewed from above).
NOTE If there is sufficient space alongside the set, it is recommended that the side panels of the cabinets be removed when making connections. This will make work easier.
Cable ratings
Cable sizes may be varied by local regulations.
IMPORTANT Cables have to be specified by local contractor.
For reasons of symmetry, if possible, and where permitted, cable type NYCWY 3-core (sleeve with full cross-section) and a separate protective conductor should be used at the output.
