Be careful to prevent injury when moving heavy objects.
It is recommended that tools such as a pallet truck be used to transport the heavy PDC.
Power cables should be laid out or installed only when the temperature is higher than
0° C.
Store power cables for at least 24 hours at room temperature before laying out them if
they were previously stored at sub-0º C.
Handle power cables with caution, especially at a low temperature. Do not drop the
power cables directly from the vehicle.
