2. COMMISSIONING
2.1 HANDLING
Lifting handles can be used to move the equipment. Please ensure the equipment is handled carefully and
that it is not dropped.
2.2 INSTALLATION
The fans on the front panel provides the forced cooling the unit needs to work efficiently. Hence care must
be taken to ensure nothing blocks the fan and the air outlet.
The unit is designed to provide a protection conforming to IP20 level and is intended for indoor use only.
2.3 CONNECTIONS
An auxiliary/control voltage is required for the operation of the fans, meters and some internal controls.
A steady 230Vac 5A or 115Vac 5A (Based on Model Selected as per Table-1) source can be connected on
the front panel marked Aux Supply with the cable provided.
2.4 SAFETY
oIt is suggested that the unit is operated by a competent person who has received adequate training.
oNever connect or disconnect the load cables under testing. Perform a full shutting down of the load as
per 3.3 before disconnection
oNever exceed the maximum test voltage of the unit.
oExtra care must be taken when relocating the load bank, dropping the unit could damage the functionality
of the unit.

3. LOAD CONTROL
3.1 CONTROL PANEL - FFLB1KW
MASTER LOAD (Green Indicator): Indicates load is in ON condition and load step switches can be activated
OVER TEMPERATURE (Red Indicator): Indicates an over temperature in the unit.
CIRCUIT BREAKER: Protects the load unit from over current & short circuit.
STEP CONTROL SWITCHES (Toggle switches): The switches control the defined power steps. The total power
of the system will be the sum of the activated steps.
LOAD OUTPUT TERMINALS (P, N & E): The test source, Phase (P), Neutral (N) and Earth (E) should be connected
to these terminals
VOLTAGE: These terminals are to be used if an external voltmeter is to be connected.
CURRENT: These terminals are to be used if an external ammeter is to be connected. The shorting link can be
removed before using an external ammeter. The link must be in place to function without an externally connected
ammeter.

MASTER LOAD (Green Indicator): Indicates load is in ON condition and load step switches can be activated
OVER TEMPERATURE (Red Indicator): Indicates an over temperature in the Unit.
CIRCUIT BREAKER: Protects load unit from over current & short circuit.
STEP CONTROL SWITCHES (Toggle switches): The switches control the defined power steps. The total power
of the system will be sum of the activated steps.
LOAD OUTPUT TERMINALS (P, N & E): The Phase (P), Neutral (N) and Earth (E) of the test source are to be
connected to these terminals
DIGITAL METERS: Meters will show the voltage and current readings.
