2   Mounting and installation 

BU 0750 GB 

Technical design subject to change 

21

 

 

2.9.1  Mains connection (PE, L1, L2, L3) 

There is no  need for special protection  on the  inverter mains input, but standard 
line protection (cf. Section 9, Technical data) and a master switch/master contac-
tor are recommended anyhow.  

Note: 

For this frequency inverter type to be connected to an 

IT-net

 only slight 

modification will be required. Please consult your supplier. 

 
 
 

2.9.2  Electromagnetic brake (+Br, -Br, PE) 

An  output  voltage  is  generated  by  the  frequency  inverter  at  the  terminals 
+Br/-Br to actuate an electromechanical brake (see Chap. 2.9 Electrical con-
nection power section).  
This  is  dependent  on  the  supply  voltage  present  in  the  frequency  inverter. 
The allocation is as follows: 

Mains input voltage (AC) 

Brake coil voltage (DC) 

400V ~ 

180V = 

460V ~ ... 480V ~ 

205V = 

230V ~ 

105V = 

Note:

  

The allocation of the correct brake or brake coil voltage must be taken into account in the design 
with reference to the frequency inverter mains voltage. 

 
 

2.9.3  Braking resistor connection (+B, -B, PE) 

When  a  three-phase  motor  is  dynamically  decelerated  (the  frequency  re-
duced),  electric  energy  is  fed  back  to  the  inverter.  This  could  result  in  an 
overvoltage situation, followed by automatic disconnection of the inverter. To 
prevent  this  from  happening,  a  braking  chopper  is  integrated  in  the  device 
which  ensures  that  the  surplus  of  recovered  energy  will  be  converted  into 
heat, provided that an external brake resistor is connected.  
The  connection  between  inverter  and  brake  resistor  should  be  as  short  as 
possible, and a shielded cable should be used.  
The switching of this connection is allowed only in the state free of voltage! 

Important:

  

The brake resistor should be rated to allow for maximum heating.  

 
 

2.9.4  Motor cable (U, V, W, PE) 

The motor cable must 

never

 be 

longer 

than

 150m in all

 (as the EMC limit values 

– Section 10.4 – will also be affected by the cable length). A 

maximum length of 

50m

 is allowed if a shielded motor cable  is used or the metal cable duct is thor-

oughly earthed.  
The switching (shooter or engine guard counter) at the output (U, V, W), while the 
frequency inverter current delivers, is not allowed! 
 

Note:

   When  the  inverter  controls  several  motors  at  a  time,  the  sum  of  the 

lengths of the individual cables is considered to be the total cable length. If 
the sum of the various cable lengths exceeds the value allowed, the inter-
nal optional motor filter should be included in the order as well.
