F and F LK-703K-110 Indicator Lamp Instructions

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

Functioning:
When voltage is present on a phase, the corresponding LED in the circuit of that phase will illuminate, indicating the presence of voltage.

Frequently Asked Questions (FAQ)

Q: What should I do if the indicator lamp does not light up?
A: Check the wiring connections and ensure that the power supply is correctly connected. Verify that there is voltage in the phases being tested.
Q: Can I use a fuse greater than 6A in the lamp connection circuit?
A: No, when an overcurrent fuse equal to or greater than 25A is installed upstream of the lamp connection point, the lamp connection circuit must be fused with a fuse no greater than 6A 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.
