5. INSTALLATION
Carefully follow all recommendations in this chapter to achieve correct electrical, hydraulic and mechanical
installations.
Before working on the electrical or mechanical part of the system, always turn off the
mains voltage. Wait at least five minutes after the power supply to the machine has
been switched off before opening the appliance. The capacitor of the continuous
intermediate circuit remains charged with dangerously high voltage even after the
mains voltage has been switched off.
Only firmly wired mains connections are admissible. The appliance must be earthed
(IEC 536 class 1, NEC and other relevant standards).
Ensure that the voltage and frequency values on the MCE/C data plate correspond to
those of the power mains.
The MCE/C is cooled by the motor cooling air, therefore it is necessary to make sure
that the motor's cooling system is in good working condition.
5.1 Fixing the unit
The MCE/C must be securely anchored to the motor by means of an adequate fixing system. The fixing
system must be selected according to the size of the motor to be used.
The MCE/C can be mechanically fixed to the motor in 2 ways:
1. Fixing with tie rods
2. Fixing with screws
5.1.1 Fixing with tie rods
Special shaped tie rods are supplied for this fixing system; the tie rods feature a male-female connection on
one side and a hook with a nut on the other. The kit also includes a dowel to center the MCE/C, which must
be screwed into the central hole of the cooling fin using thread locking adhesive. The tie rods must be
uniformly distributed around the circumference of the motor. The male-female connection side of the tie rod
must be inserted in the special holes on the MCE/C's cooling fin, while the other side hooks onto the motor.
The nuts of the tie rods must be tightened until the MCE/C and the motor are tightly fixed together and
centered.
5.1.2 Fixing with screws
The kit for this fixing system includes a fan cover, "L" shaped brackets to fix the inverter to the motor and
some screws. To install the inverter remove the motor's original fan cover and fix the "L" shaped brackets to
the stud bolts on the motor casing (position the "L" shaped brackets so that the hole to fix the inverter to the
fan cover is in line with the centre of the motor); then fix the fan cover supplied to the MCE/C cooling fin
using the screws and thread locking adhesive. Now fit the fan cover-MCE/C assembly on the motor and
insert the special anchoring screws between the brackets mounted on the motor and the fan cover.
