4.1 Electromagnetic Compatibility (EMC)
MCE/C inverters respect standard EN 61800-3, in the C2 category, for electromagnetic compatibility.

5. INSTALLATION
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 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.
5.2 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.
6. ELECTRICAL CONNECTIONS
Always switch off the mains power supply before working on the electrical or mechanical part of the system. Before opening
the equipment, wait at least 15 minutes after disconnecting it from the power supply. The capacitor of the direct current
intermediate circuit remains charged with dangerously high voltage even after the mains power has been turned off.
Only firmly cabled mains connections are admissible. The appliance must be earthed (IEC 536 class 1, NEC and
other applicable standards).
Ensure that the voltage and frequency on the data plate of the MCE-C are the same as those of the power mains.
