2.2 Safety Information
This section contains safety information that must be observed at all times when working on or with
the product. To prevent personal injury and property damage and to ensure long-term operation of
the product, read this section carefully and observe all safety information at all times.
Danger to life from electric shock due to live voltage
High voltages are present in the live components of the product. Touching live components results
in death or serious injury due to electric shock.
• Wear suitable personal protective equipment for all work on the product.
• Do not touch any live components.
• Unless live voltage is absolutely necessary, always disconnect the product from voltage
sources before performing any work (see Section 8 "Disconnecting and Reconnecting",
page 46).
Danger to life from electric shock due to live DC cables
DC cables connected to PV modules that are exposed to sunlight are energized. Touching live
cables results in death or serious injury due to electric shock.
• Prior to assembling the DC cables, ensure that the DC cables are voltage-free.
• Wear suitable personal protective equipment for all work on the product.
Danger to life from electric shock due to ground fault
If there is a ground fault, system components that are supposedly grounded may in fact be live.
Touching incorrectly grounded components results in death or serious injuries from electric shock.
• Before working on the system, ensure that no ground fault is present.
• Wear suitable personal protective equipment for all work on the product.
Danger to life from electric shock due to damaged product
Operating a damaged product can lead to hazardous situations that result in death or serious
injuries due to electric shock.
• Only operate the product when it is in a flawless technical condition and safe to operate.
• Check the product regularly for visible damage.
• Make sure that all external safety equipment is freely accessible at all times.
• Make sure that all safety equipment is in good working order.
• Wear suitable personal protective equipment for all work on the product.
