Installation & Connection
3.1
Installation
Inverter should be installed vertically, as shown in Fig 3-1. Sufficient ventilation space should be ensured in
its surrounding. Clearance dimensions (recommended) are available from Table 3-1 for installing the
inverter.

Connection
In case of 3-phase input, connect R/L1,
S/L2 and T/L3 terminals (L1/R and
L2/S terminals for single-phase) with
power source from network and
/PE/E to earthing, U, V and W terminals to motor.
Motor shall have to be ground connected. Orelse electrified motor causes interference.
For inverter power lower than 15kw, braking cell is also built-in. If the load inertia is moderate,
it is Ok to only connect braking resistance.

Note: power terminals L1/R, L2/S of single-phase 230V 1.5KW and 2.2KW are connected
to 230V of power grid; L3/T is not connected.
The inverters below 11kw have no the terminal “
