The temperatures are set at the beginning of the test and maintained constant during the test. Test voltage shall be as specified in Table 1. It is set at the beginning of the test and maintained constant during the test. The environmental conditions during the test shall be as specified in Tables 1 and 2 of EN 14511-2:2011. Air flow rates shall be the same as that used for rating capacity test, as specified in EN 14511-2:2011. Deviation between individual values and set values shall be between:  zero and minus twice the permissible deviation according to Table 2 of EN 14511-3:2011, for the upper limit of use;  zero and plus twice the permissible deviation according to Table 2 of EN 14511-3:2011, for the lower limit of use. Uncertainty of measurement shall be as specified in Table 1 of EN 14511-3:2011. 4.2.2 Test at maximum operating conditions (cooling mode) When operated at conditions stated in Table 2 during 1 h, then switch off for 5 min, and then switched on again for 1 h, the unit shall meet the following requirements:  the unit motor shall operate continuously for the first hour without tripping of the motor overload protective devices;  after the shut-down period of 5 min, the unit shall restart automatically no more than 5 min after restarting of the compressor;  the unit motor shall operate again continuously for the rest of the second hour without trippin
