F and F LK-703K Indicator Lamp Owner's Manual

Purpose
The LK-703K indicator lamp is used to visually signal the presence of voltage in individual phases of a 3-phase network. It is designed for space-saving installation in switchgear.

Functioning
The presence of voltage on a phase is indicated by the illumination of the corresponding LED in the circuit of that phase.

Mounting

Check the phase sequence.

Disconnect the power supply.
Fix the indicator lamp on the rail.

Connect according to the provided wiring diagram.
Switch on the power supply.

Check for correct operation.

FAQ

Q: What should I do if the indicator lamp does not illuminate?
A: Check the power supply connection, ensure correct wiring as per the diagram, and verify the presence of voltage in the phases.

Q: Can I use a fuse greater than 6 A in the lamp connection circuit?
A: No, if an overcurrent fuse equal to or greater than 25 A is installed upstream of the lamp connection point, the lamp connection circuit must be fused with a fuse no greater than 6 A to ensure safe operation.

Purpose
The LK-703K indicator lamp is used to visually signal the presence of voltage in individual phases of a 3-phase network. The small size of the housing (width 6.2 mm) allows space-saving installation in the switchgear.

Functioning

The presence of voltage on a phase is signalled by the illumination of the corresponding LED included in the circuit of that phase.

Where an overcurrent fuse equal to or greater than 25 A is installed upstream of the lamp connection point, the lamp connection circuit must be fused with a fuse no greater than 6 A.

Mounting

Check the phase sequence.
Disconnect the power supply.

Fix the light on the rail.
Connect according to the diagram.

Switch on the power supply.
Check for correct operation.
