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.
