LV halogen dimmer insert for inductive load

Operating instructions

Art. no. MTN572599

For your safety

¼

DANGER

Risk of fatal injury from electrical current.

All work on the device should only be carried out by trained and skilled electricians. The countryspecific regulations must be followed.

¼

DANGER

Risk of fatal injury from electrical current.

The outputs may carry an electrical voltage even when the dimmer is switched off. Always disconnect the fuse in the incoming circuit from the supply before working on connected loads.

LV halogen dimmer insert introduction

Using the LV halogen dimmer insert (referred to below as dimmer ) enables you to switch and dim the following ohmic and inductive loads with a rotary knob:

– Incandescent lamps or halogen lamps 20 – 500 VA

– Low-voltage halogen lamps with dimmable, inductive transformer 20 – 500 VA

½

CAUTION

Damage to the device.

The dimmer requires a minimum load of 20 VA for operation. If this is not met, the dimmer may be damaged.

½

CAUTION

Damage to connected devices.

Connected devices can be damaged if you connect capacitive loads.

½

CAUTION

Damage to the device.

When transformers are used: Only connect dimmable, wound transformers to the dimmer.

| If you do not install the dimmer in a single, standard flush mounting box, the maximum permissible load is reduced as follows, due to the restricted heat dissipation:

| Do not use dimmers on socket-outlets! The risk of overloading and the risk of unsuitable appliances being connected is too high.

Completing the dimmer

Complete the dimmer with a frame and a central plate for rotary dimmer inserts up to 600 VA (art. nos.

MTN5699.., MTN5670.. MTN5720..).

DANGER

Risk of fatal injury from electrical current.

The outputs may carry an electrical voltage even when the dimmer is switched off. Always disconnect the fuse in the incoming circuit from the supply before working on connected loads.

1 Wire up the dimmer for the application.

Applications:

– Dimmer as a one-way switch or instead of a twocircuit switch:

Operating the dimmer

You can switch ( A ) and dim ( B ) the loads using the rotary knob.

What should I do if there is a problem?

The electrical load does not light up.

Replace the fuse. Reduce the connected load before repeating.

The dimmer dims independently in the operating state.

Allow the dimmer to cool down and reduce the connected load.

The dimmer buzzes during operation.

Buzzing during operation may occur depending on design, and does not signify a malfunction.

Replacing the fuse

¼ DANGER

Risk of fatal injury from electrical current.

Switch off the mains voltage.

– Dimmer as a two-way switch:

| A neutral conductor is not required.
