3.2.7 Wall Mounting
3.2.7 Wall Mounting
When wall mounting the main unit, use the included screws.
WARNING
• Make sure that the wall that the unit will be attached to is strong enough to support
  approximately 5 times the weight of the unit. If not, it is necessary for the wall to be reinforced.
• Only use the wall-mounting equipment (screws and washers) included with the PBX.
• Be careful not to drop any components. Dropping components may damage them or cause an
  injury.
• Proper earthing (connection to earth) is very important to reduce the risk to the user of
  electrocution or to protect the PBX from the bad effects of external noise in the case of a
  li
htnin
 strike. 
See "3.2.4 Frame Earth Connection".
CAUTION
• Make sure to install all necessary optional service cards in the PBX before performing the wall mounting
  procedure. If it is necessary to install or remove a card, make sure to detach the PBX from the wall
  before installing or removing the card.
• Do not block the openings of the PBX. Allow space of at least 20 cm above and 10 cm at the sides of
  the PBX.
• Make sure that the surface behind the PBX is flat and free of obstacles, so that the openings on the
  back of the PBX will not be blocked.
• If the PBX is not installed properly using the securing correct methods, the PBX may fall causing serious
  damage.
• When drivin
 the screws into the wall, be careful to avoid touchin
 an
 metal laths, wire laths or 
lates
  in the wall.
• When this product is no longer in use, make sure to detach it from the wall.
