5. 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-150/C are the
same as those of the power mains.
5.1 Connection to the Power Supply Line
The connection between the three-phase power supply line and the MCE-150/C must be made with a 4-core
cable (3 earth). The characteristics of the power supply must satisfy the indications in
Table 1 .
The input terminals are the ones marked with the words LINE RST and with an arrow entering the
terminals, see Figure 1 .
Figure 1: Electrical connections
The minimum section of the input and output cables is 6 mm2 to guarantee correct tightening of the cable
clamps, while the maximum section accepted by the terminals is 16 mm².
