PROLiNK PA40-120 Operation Manual Download Page 4

An all-pole mains switch with a contact separation of at least 3 mm in each pole shall be incorporated in

the electrical installation of the building.

When Installing the Unit

    Never  plug  in  nor remove the power  supply  plug

    with  wet  hands,  as  doing  so  may cause electric

    shock.

    When unplugging  the  power  supply cord, be sure

    to grasp the  power  supply  plug; never  pull on the

    cord  itself.  Operating   the  unit   with  a  damaged

    power  supply  cord  may  cause  a  fire  or  electric 

    shock.

    When moving the unit, be sure to remove its power 

    supply cord  from the  wall  outlet.  Moving  the unit

    with the  power  cord  connected  to  the outlet may

    cause damage to the power cord, resulting in fire or 

    electric shock. When  removing the power cord,  be

    sure to hold its plug to pull.

  Do not block the ventilation slots in the unit's cover.

  Doing so may cause heat to build up inside the unit 

  and result in fire.

  Avoid installing the unit in humid or dusty locations,

  in locations exposed to the direct sunlight, near the 

  heaters, or in locations generating  sooty smoke or

  steam  as  doing  otherwise  may  result  in  fire  or 

  electric shock.

When the Unit is in Use

    Do not place heavy objects on the unit as  this  may

    cause   it  to  fall  or  break   which   may   result   in 

    personal   injury    and/or    property    damage.   In

    addition,  the  object  itself  may  fall  off  and  cause

    injury  and/or  damage.

    Make  sure   that   the  volume   control   is   set   to

    minimum  position   before  power  is  switched   on.

    Loud noise produced at high volume when power is 

    switched  on  can  impair  hearing.

    Do not operate  the  unit  for an  extended  period of 

    time with  the sound distorting. This  is  an indication

    of  a  malfunction,  which  in  turn  can cause heat to

    generate and result in a fire.

    Contact  your 

 dealer  as  to the  cleaning. If  

    dust  is  allowed  to accumulate  in  the  unit  over  a  

    long  period of  time, a  fire  or  damage  to  the  unit  

    may  result.

prolink

  If dust accumulates on the power supply plug or in

  the  wall  AC  outlet,  a  fire  may  result.  Clean  it 

  periodically. In addition, insert the plug in the wall 

  outlet securely.

  Switch off  the  power, and unplug the power  supply

  plug  from the  AC outlet  for  safety  purposes when 

  cleaning  or  leaving the unit unused for  10  days or 

  more. Doing otherwise  may cause a fire  or  electric 

  shock.
