S-DRIVE - WARNING SUMMARY                   PG DRIVES TECHNOLOGY 
SK76745/10 
2.21  Inhibit 3 Speed 
If the Inhibit Speed is greater than 0 then the controller will not enter an inhibit state. Chapter 2 
section 4.12.2. 
2.22  Drive Motors 
The scooter manufacturer is responsible for ensuring that the controller is matched to the motor 
resistance.  Failure  to  do  this  may  result  in  poor  control  characteristics,  which  in  extreme 
instances can make a scooter uncontrollable and potentially unsafe. PGDT accepts no liability for 
losses of any kind arising from failure to comply with this condition
.
 
The  scooter  manufacturer  is  responsible  for  always  ensuring  that  any  replacement  motors  or 
gearboxes  are  fully  compatible  with  the  originals  that  the  controller  was  designed  to  match. 
Failure to do this may result in poor control characteristics, which in extreme instances can make 
a scooter uncontrollable and potentially unsafe. PGDT accepts no liability for losses of any kind 
arising from failure to comply with this condition. 
Users  or  service  personnel  must  not  move  a  controller  from  one scooter  type  to  install  it  on  a 
different  scooter  type.  Controllers  with  different  part  numbers  may  have  both  hardware  and 
software  differences  to  ensure  that  they  are  compatible  with  the  electrical  and  dynamic 
characteristics of their specific target vehicles. The characteristics of one type of controller may 
not  be  compatible  with  a  different,  unauthorized  scooter.  Failure  to  observe  this  warning  could 
result  in  an  unsafe  setup  for  the  scooter  user  and  may  create  a  fire  hazard  depending  on  the 
motors, wiring, connectors and circuit breakers installed on the unauthorized chair. PGDT accepts 
no  liability  for  losses  of  any  kind  arising  from  failure  to  comply  with  this  condition.  Chapter  2 
section 5. 
2.23  Freewheeling 
It is the responsibility of the scooter manufacturer to ensure that adequate precautions are taken 
to warn the user against the hazards of freewheeling the scooter at excessive speeds. It is also 
the responsibility of the scooter manufacturer to utilize a suitable freewheel mechanism to reduce 
these  risks. PGDT  accepts  no  liability  for  losses  of  any  kind  resulting from  excessive  freewheel 
speeds of a scooter. Chapter 2 section 5.2. 
2.24  Charger Connections 
Do not exceed the maximum charging current of 9 A rms. Always use the PGDT specified charger 
connectors.  Failure  to  observe  these  conditions  could  result  in  poor  contact  resistance  in  the 
charger  connector  resulting  in  overheating  of  the  charger  plugs.  This  presents  a  potential  burn 
hazard  for  the  user.  PGDT  accepts  no  liability  for  losses  of  any  kind  arising  from  failure  to 
comply with this condition. Ensure that the charger plug  pins are of the correct. 
The scooter manufacturer must install a suitable fuse to protect the scooter’s wiring. PGDT recommends 
that the fuse is fitted as close as possible to the 4-way Molex connector. Failure to comply with this 
could result in a fire hazard. PGDT accepts no liability for losses of any kind arising from failure to 
comply with this condition. Chapter 2 section 6.
