High-temperature components: compressor, refrigerant pipe, and electric heater.
High-pressure components: compressor and refrigerant pipe.
To avoid frostbite caused by refrigerant leaks, take protective measures such as wearing
antifreeze gloves when handling refrigerant.
Low-temperature component: evaporator.
Cables must be laid out and installed only when the temperature is higher than 0° C.
Cables previously stored at subzero temperatures must be stored at room temperature for
at least 24 hours before they are laid out.
Handle cables with caution, especially at a low temperature. Do not drop cables from
vehicles to the ground.
Cables must be routed with a distance of at least 30 mm between the cables and the DC
busbar, shunt, and fuse. This prevents damage to and decelerates deterioration of the
insulation layer of the cables. Cables must be flame-retardant and must not be routed
behind the air inlets or outlets of the cabinet. The air inlets and outlets must not be
blocked.
Ensure that the equipment is not located near heat sources or directly exposed to
sunlight.
To avoid explosion or refrigerant leaks, keep sources of ignition and high-temperature
objects far away from the equipment. This is especially important for equipment
containing high-pressure nitrogen or refrigerant.
