3. ELECTRICAL INSTALLATION
3.1. Power terminals
Symbol Name Description
L1/R, L2/S, L3/T Main power inputs
Connect the 3-phase input power lines
Input voltage for F1S-4: 380-460V AC 50/60Hz
Input voltage for F1S-2: 200-230V AC 50/60Hz
U, V, W Inverter outputs Connect a 3-phase motor
R0, T0 Auxiliary power input
For a backup of the control circuit power supply, connect AC power lines same as that of
the main power input
P1, P(+) DC reactor connection
Connect a DC reactor (DCRE) for improving power factor (an option for the inverter whose
capacity is 55 kW or below)
P(+), N(-) DC link bus An optional PWM regenerative converter may be connected to these terminals
R1, T1 Auxiliary power input for the fans
Auxiliary power input for the fans for 55KW or above inverters (400V AC series) or 45KW or
above inverters (200V AC series)
Grounding terminals for the inverter’s chassis (or case) and motor. Earth one of the
G x 2 Ground terminals
terminals and connect the grounding terminal of the motor. Inverters provide a pair of
grounding terminals that function equivalently
3.2. Control terminals
The FRENIC-Eco has 7 digital inputs, 3 transistor outputs, 2 relay outputs and 2 analog outputs. All of them are programmable.
