• Free-standing:

If the unit is to be free standing, it is strongly advised that the four low-profile rubber 
feet (supplied) be attached to the underside of the unit close to the dimpled mounting 
holes. This will help prevent the unit sliding about and also stop any surface on which 
it is placed being marked.

• Wiring:

All  connecting  cables  should  enter  the  unit  via  the  black  16mm  ‘blind’  grommets 
located in the sides of the unit. These blind grommets are designed to be pierced 
by a suitable tool to allow the cables to pass through them. These grommets should 
always  be  removed  from  the  case  before  attempting  to  make  any  form  of  hole  in 
them which will prevent damaging the circuit board and any existing wiring.

Safety note:

 To prevent injury, extreme care must always be exercised when using 

any sharp or pointed implement to pierce these grommets. Alternatively, the blind 
grommet can be removed and replaced with a standard 16mm ‘open’ grommet or 
any other form of suitable cable entry device if deemed more appropriate (e.g. M16 
cable glands, etc).

Note:

 It is strongly advised that the unit installation is fully functionally tested using 

the supplied memory stick before replacing any of the files with new ones.
If  you  have  any  concerns  regarding  the  installation  of  this  unit  please  contact  our 
technical department.

Installation procedure:

• Important:

• Please  read  the  Important  Notes  section  at  the  beginning  of  these  instructions 
  before installing this device.
• Do  not  connect  power  to  the  device  until  all  the  installation  wiring  and  all  the 
  connections have been completed.

The  LB-5A  is  supplied  in  a  painted  metal  enclosure  that  can  be  used  as  a 
free-standing unit or secured to a flat surface by means of the four dimpled mounting 
holes located in the corners of the base of the unit. To gain access to the unit, unscrew 
the four lid retaining screws and remove the lid.

• Permanent Fixing:

Important note: When permanently fixing the unit to a surface the circuit board must 
first be removed from the base by unscrewing the six mounting screws which will 
give full access to the mounting holes. Attempting to secure the unit with the circuit 
board still in place could lead to inadvertent damage to the unit and invalidate the 
warranty.
