Connection To The Electropump; Earth Connection; Figure 2: Earth Connection - DAB MCE-30/C Installations- Und Wartungsanleitungen

ATTENTION: The thermal magnetic circuit breaker and the power cables of the MCE-55/C and of the pump
must be of a size suited to the system; if the indications given in the manual do not agree with the regulation
in force, use the regulation as reference.
5.2

Connection to the Electropump

The connection between the MCE-55/C and the electropump is made with a 4-core screened cable (3
phases + earth).
At output an electropump must be connected to a three-phase power supply with the characteristics
specified in Table 1.
The output terminals are the ones marked with the words PUMP UVW and with an arrow leaving the
terminals, see Figure 1.
The rated voltage of the electropump must be the same as the MCE-55/C power supply voltage.
The utility connected to the MCE-55/C must not absorb a current higher than the maximum that can be
supplied, indicated in Table 1.
Check the data plates and the type of connection (star or delta) of the motor used to respect the above-
mentioned conditions.
The incorrect connection of the earth lines to a terminal other than the earth terminal
may cause irremediable damage to the whole equipment.
The incorrect connection of the power supply line to the output terminals intended for
the load may cause irremediable damage to the whole equipment.
It is recommended to install a differential switch to protect the system, which must
have correct dimensions, such as: Class A (AS for models with three-phase power
supply), with adjustable leakage current, selective, protected against sudden tripping.
The automatic differential switch must be marked with the following two symbols:

Earth Connection

The earth connection must be made with cable lugs tightened as shown in Figure 2:
