General safety rules
Safety is important. Observe and follow these safety precautions during all installation and maintenance work.
The ST90 system operates on 115 VAC and/or 230 VAC at 50/60 Hz. This voltage is lethal! You must never work alone on high-voltage equipment!
The hull unit is powered by a 3-phase high voltage.
This equipment must be installed, adjusted, and serviced only by qualified electrical maintenance personnel familiar with the construction and operation of the equipment and the hazards involved. Failure to observe this precaution could result in bodily injury.
- Personnel requirements
All personnel must be trained in relevant installation and maintenance work.
- Personal protection
Installation personnel must wear suitable work clothes. The work clothes must not contain sufficient static to ignite. Always wear a hard hat and suitable protective footwear while handling heavy objects.
- Power and ground
You must always turn off all power before installing or maintaining the ST90 system. Disengage the main circuit breaker.
For safety reasons, two persons must always be present during troubleshooting with power turned ON.
All ST90 system units must be properly grounded.
- First aid
Read and understand the applicable first aid instructions related to electric shock.
A first aid kit must be available whenever installation or maintenance work is in progress.
- Weight
The various parts of the system may be heavy. Make sure that the appropriate tools and certified lifting equipment are available. Always wear a hard hat and suitable protective footwear while handling heavy objects.
- Cables
Each electric cable must be handled carefully. This is important to avoid damage to the cable. This is also important to avoid electric shock in the event that the cable is unintentionally connected to a power source.
- Cabinets
Do not open racks or cabinet doors while sailing in rough seas. Doors and/or cabinet parts may suddenly swing open and cause damage or injury.
