Important installation information!
Installation and commissioning may only be done by an authorised
electrician. Mains power (230V~/50 Hz) to electrical equipment
must be switched off during installation. Applicable laws and
standards of the country in which the device is operated must be
observed!
Fixing
D MLS2001AHBF
Depth required behind ceiling: 62mm from front flange plus an al-
lowance for the minimum bend radius of the cable. Sinking box fits
into a 89mm diameter hole in ceiling tile or plasterboard ceiling.
Note: If the sinking box is being fitted to a hard substrate such as
metal, increase the hole size to 91mm. To avoid damage to ceiling
tile, do not overtighten. No access above the ceiling is required..
D MLS2001AHBSM
The housing may be secured to a hard surface or a BESA box. The
unit fits into the housing with a simple bayonet action.

Note:
When operating in ‚Regulating Photocell' mode, a closed feedback
loop is formed by the luminaire, the reflective surface beneath,
and the photocell. For this control loop to function correctly, the
photocell must have a good view of the reflected light only from
the luminaire(s) under its control – NOT from adjacent luminaires
not under its control. This means that the higher the detectors are
mounted, the further apart they must be in order to ensure that they
see mostly ‚their own light'. Therefore, it is recommended that de-
tectors are mounted on a pitch not less than 50% of the mounting
height when using the regulating photocell function.
Connection
A 10A type C MCB is recommended for the supply. A means for
disconnection must be incorporated in the fixed wiring according
to the wiring regulations.
The MLS Bus must be connected to the MLS Bus Network. An
MLS Bus Power Supply is required for each network of up to 200
MLS devices. Refer to the MLS Bus Power Supply Installation
Instructions before commencing any bus wiring. It is imperative
that the MLS Bus is wired in the correct type of cable. Normally
this will be 1.5mm² unscreened twisted pair. See Application Note
AN4001 for details. Do not connect mains to the MLS Bus wiring.
