S-DRIVE – APPENDIX - A                    PG DRIVES TECHNOLOGY 
SK76745/10 
10.4  On/off indicator 
S-Drive  products  support  on/off  indication  in  conformity  with  the  standard  if  a  suitable  indicator  is  provided  by  the  scooter 
manufacturer. 
10.5  Connectors 
The S-Drive does not have connectors intended for use by the occupant or assistant. 
10.6  Audible noise 
S-Drive  products  do  not  make  any  contribution  to  the  overall  noise  produced  by  the  scooter  in  the  drive  test  or  the  ancillary 
equipment test. 
10.7  Acoustic warning device 
Not applicable to S-Drive products. 
11.1  Control device fatigue 
This requirement does not apply directly to S-Drive products. However, throttle controls fitted by the scooter manufacturer for use 
with the S-Drive should conform to the requirement. 
11.2  Switch cycle life 
This requirement does not apply directly to S-Drive products. However, switches fitted by the scooter manufacturer for use with the 
S-Drive should conform to the requirement. 
11.3  Connector cycle life 
No connectors provided on S-Drive are intended for daily use. 
12.1  Connector interchange 
The smaller S-Drive products (S-45, S-70 and S-90) have motor and battery connectors that are interchangeable. However, they 
are not intended for use by the occupant or assistant. 
12.2  Wire routing 
This requirement does not apply directly to S-Drive products, but it does apply to the way they are installed. All wiring used with S-
Drive products should be fitted in accordance with this requirement. 
12.3  Wire colours 
This requirement does not apply directly to S-Drive products. However, battery wiring fitted by the scooter manufacturer for use 
with the S-Drive should conform to the requirement. 
12.4  Battery tapping 
Not applicable to S-Drive products. 
13.1  Substance/liquid ingress 
S-Drive  products  meet  IPX4  as  specified  in  IEC  60529.  This  implies  they  meet  or  exceed  the  requirements  of  ISO  7176-9 
concerning ingress of liquids.  
13.2  Substance leakage 
S-Drive products contain small quantities of liquid electrolyte in electrolytic capacitors. The risk of leakage is negligible due to the 
sealing provided, and the products meet requirement b). 
13.3  EMC 
S-Drive products are designed and tested meet the requirements of ISO 7176-21:2003 in typical scooter installations. Since the 
EMC performance is dependent on the properties of the scooter 
in which the S-Drive is installed, it is necessary for the scooter manufacturer to confirm that the complete vehicle meets the EMC 
requirements. 
Note that a new edition of ISO 7176-21 has been published in 2009. The new edition of EN 12184 requires conformity with the 
previous (2003) edition of ISO  7176-21. The  requirement in EN 12184:2009 is treated as taking  precedence  over the  undated 
reference to ISO 7176-21 in ISO 7176-14:2008.
