Range of DB Units covered by this Manual
Table 1-1 shows the full range of DB Units available for MV3000e drives. There is one DB Unit
for each frame size at each available supply voltage rating. Electrical data, dimensions and
weights are provided in Section 2.

Range of Standard Braking Resistors supplied by Converteam
Converteam
produces a range of standard braking resistors designed to allow each internal
DB Unit to produce the maximum possible braking effort. Section 2.1 shows the braking
resistor model number associated with each DB Unit. The maximum permitted sizes of resistor
connecting cables are given in Section 3.7.
Instruction Sheet T1947 provides detailed installation instructions for these resistors.
1.5 Identity
Codes
The code used to identify DB Units is explained in Figure 1-2 below. The figure shows the
code for a standard duty DB Unit rated at 92 Amps and with a maximum supply voltage of 525
V.

Use of Metric Units
The ALSPA MV3DB range of DB Units has been designed to IEC standards using SI units. In
this manual approximate values for inches, lb and hp are also included for convenience.
