Work on the device/system by unqualified personnel or failure to comply with 
warnings can result in severe personal injury or serious damage to material. 
Only suitably qualified personnel trained in the setup, installation, 
commissioning and operation of the product should carry out work on the 
device/system. 

 

Only permanently wired input power connections are allowed. This equipment 
must be grounded (IEC 536 Class 1, NEC and other applicable standards). 

 

If a Residual Current-operated protective Device (RCD) is to be used, it must 
be an RCD type B. 

 

Machines with a three-phase power supply, fitted with EMC filters, must not be 
connected to a supply via an ELCB (Earth Leakage Circuit-Breaker EN50178 
Section 5.2.11.1). 

 

The following terminals can carry dangerous voltages even if the inverter is 
inoperative: 
- power supply terminals L1, L2, L3 
- motor terminals U, V, W 
- additionally the terminals DC+, DC- 

 

Always wait 5 minutes to allow the unit to discharge after switching off before 
carrying out any installation work. 

 

This equipment must not be used as an ‘emergency stop mechanism’ (see EN 
60204, 9.2.5.4) 

 

The minimum size of the earth-bonding conductor must be equal to or greater 
than the cross-section of the power supply cables. 

 

 

CAUTION 
The connection of power and motor cables to the inverter must be carried out as 
shown in Figure 2-10 to prevent inductive and capacitive interference from 
affecting the correct functioning of the inverter.
