The safety instructions (

Sec. 2, P. 6) must be strictly observed during the electrical installation!
3.1
Installation instructions
●
Run power cables and electronic leads in separate cable ducts.
●
Power cable: based on the input current I
mains
at rated load
(Data
→
Sec. 6).
●
Motor cable: based on output rated current I
N
(Data
→
Sec. 6).
●
The input fuses must be installed at the beginning of the power cable, directly after the busbar
junction (Wiring diagram
→
Sec. 3.3: F11).
●
An earth leakage circuit-breaker is not permissible as the sole protection device. Leakage
currents > 3.5 mA can occur in normal inverter operation.
●
Alternate operation of two motors from one inverter: a changeover contactor must be provided
for each of the two motor cables. Changeover contactors may only be actuated when the inverter
is inhibited!
●
Only an inductive/resistive load (motor) may be connected at the inverter output, no capacitive
load!
●
For jogging, use the commands clockwise STR / counterclockwise STL.
The mains contactor K 11 must not be used for jogging, but only for switching the inverter on
and off!
●
Recommendation: after power-down, wait minimum 30s before powering the inverter up again!
●
The binary and analogue outputs are isolated by optocouplers. However, they are neither
short-circuit-proof nor external-voltage-proof and can be destroyed by short-circuits or if an
external voltage source is connected!
●
Brake chopper: Loop in NC contact (TL. 7/8) in inverter power supply line (Connection
→
Se. 3.3).
Cross-section based on the inverter rated current (Data
→
Sec. 6). Under rated conditions supply
leads to the brake chopper carry high DC voltages (approx. 500V).
