ISO 7176-14 requires you to provide protection against short circuits in the battery
wiring and the power loom or the extremely unlikely event of a short circuit in the
controller.
Place a suitable circuit breaker in series with the battery supply, for example in the link
between two 12V batteries. If your batteries are held in separate enclosures, you must
provide a circuit breaker with each of them.
The rating of the circuit breaker must match the capacity of the wiring specified in
section 3.5. For Egis 70A models the circuit breaker rating should not exceed a 40A
maximum rating. For Egis 110A models the circuit breaker rating should not exceed
70A.
ISO 7176-14 states that the minimum operating time for the circuit breaker when the
scooter is stalled is 15 seconds.
It is recommended that the battery positive and negative wiring to the Egis is kept as
short as possible
The scooter manufacturer must install a suitable circuit
breaker to provide protection against short circuits in the
battery wiring, power loom or the control system. 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.
3.3 Motor Connections
If a circuit breaker is fitted in series with the motor, it is essential that the scooter assumes
a safe condition the moment the circuit breaker operates. You must therefore fit a
circuit breaker with an auxiliary switch which inhibits the scooter from driving, see section
7.1.
3.4 Brake Connections
The solenoid brake should be a 24V type with a maximum current rating of 2A.
If the controller switches the solenoid brake and the current is less than 12mA or greater
than 5A, the controller will detect a solenoid brake Trip.
