Safeties and precaution
- Over and under protections for the load (both AC & DC) and if frequency is varied.
- Manual emergency stop.
- Auto cutoff on low oil pressure, temperature of coolant and the engine.
- Intake air restriction indication and alarm
- Auto shut down in 30 sec of idle running when stopped.
- Can be switched safely between IDLE and Run modes.
- Cable stowage unit with connectors’ stowing socket and safety for inadvertent vehicle movement.
- RPM limit safety.
- Battery isolator switch with removable key.
- Minimum coolant temperature set to go from Idle to Run mode. (By pass possible)
- Push Type emergency stop switch.
- Safety interlocks to prevent vehicle’s starting until GPU is shut down and all power cables and adopters/connectors are properly stowed in appropriate places.
