•
Only permanently-wired input power connections are allowed. This equipment must be
grounded (IEC 536 Class 1, NEC and other applicable standards).
•
Only type B ELCBs should be used with Frame Size A to Frame Size F. 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 - see DIN VDE 0160, section 5.5.2 and
EN50178 section 5.2.11.1).
•
The following terminals can carry dangerous voltages even if the inverter is inoperative:
•
The power supply L/L1, N/L2, L3 resp. U1/L1, V1/L2, W1/L3. the motor terminals U, V,
W resp. U2/T1, V2/T2, W2/T3. and depending on the frame size the terminals DC+/B+,
DC-, B-, DC/R+ resp. C/L+, D/L-
