8. Mounting
Danger from electrical voltage
The unit must be mounted by specialist personnel (qualified electricians). The personnel must ensure that the
cabinet is disconnected from the electrical supply for the duration of the mounting operation. Therefore take the
cabinet out of operation, following the relevant instructions before mounting work commences.
Danger through incorrect work on the unit. Only specialists are allowed to put the unit into operation.
Mounting preparations
Several points must be checked before the unit can be mounted. These checks must be made to ensure safety
and the trouble-free operation of the unit. These checks must be carried out with absolute thoroughness to
ensure that the unit works perfectly.
Transport damage check
On delivery the carton containing the unit must be examined for signs of transport damage. Any transport
damage to the carton could indicate that the unit itself has been damaged in transit which in the worst case
could mean that the unit will not function.
Location and space requirements
The location of the cabinet must allow for sufficient air circulation to and from the unit. The unit should be
mounted roughly horizontally. It is therefore advisable to check that the cabinet is in a horizontal position. The
max. deviation from the vertical or horizontal should not excess 20 degrees.
Sealing
To guarantee that the unit works perfectly ensure that, the control cabinet is completely sealed (min. NEMA 12)
and a good seal exists between the control cabinet and the unit. If necessary the cabinet mounting surface
should be reinforced.
