Safety instructions

General safety instructions 

Protect the unit against moisture, dirt and any kind of damage during transport, storage 
and operation. Do not operate the unit outside the specified technical data.

Never open the housing. If not otherwise specified, install in closed housing (e.g. 
distribution cabinet). Earth the unit at the terminals provided, if existing, for this purpose. 
Do not obstruct cooling of the unit. Keep out of the reach of children.

Life threatening voltages are present within and around an open control cabinet.

When installing this product in a control cabinet or any other areas where dangerous 
voltages are present, always switch off the power supply to the cabinet or equipment.

Risk of fire if not installed and operated properly.

Follow all applicable electrical safety standards, guidelines, specifications and regulations 
for installation, wiring and operations of this product.

The Raspberry Pi board could generate a substantial amount of heat when the software 
forces the CPU and/or GPU to operate at high load levels. Ensure that the product is 
properly installed and ventilated to prevent overheat.

The connection of expansion devices to this product may damage the product and other 
connected systems, and may violate safety rules and regulations regarding radio 
interference and electromagnetic compatibility.

Use only appropriate tools when installing this product. Using excessive force with tools 
may damage the product, alter its characteristics or degrade its safety.

Battery and external rechargeable battery 

This product uses a small lithium non-rechargeable battery to power its internal real time 
clock (RTC). It also optionally uses an external rechargeable lead-acid battery for the 
uninterruptible power supply.
