4.2.5.3 Test method
At an ambient room temperature (20 ± 5) °C, discharge the fully charged EPAC
battery to the discharging limit specified by the EPAC or ESA manufacturer at the
maximum current allowable by the system and record it. Measure the cable and plug
temperatures and ensure, by examination, that there is no deterioration of the
insulation on either assembly.
The increase of outer surface temperature of parts that can be touched shall be ≤ 60
K while in use on performance test rig.
4.2.6 Wiring
Requirements on wiring shall be checked according to the following sequence at an
ambient room temperature (20 ± 5) °C.
a) Wire ways shall be smooth and free from sharp edges.
b) Wires shall be protected so that they do not come into contact with burrs, cooling
fins or similar sharp edges that may cause damage to their insulation. Holes in
metal through which insulated wires pass shall have smooth well-rounded
surfaces or be provided with bushings.
c) Wiring shall be effectively prevented from coming into contact with moving parts.
Compliance with a), b), c) shall be checked by inspection.
d) Separate parts of the EPAC that can move in normal use or during user
maintenance relative to each other, shall not cause undue stress to electrical
connections and internal conductors, including those providing ground continuity.
If an open coil spring is used to protect wire, it shall be correctly installed and
insulated. Flexible metallic tubes shall not cause damage to the insulation of the
conductors contained within them.
Compliance with d) shall be checked by inspection and by the following test method.
If flexing occurs in normal use, the appliance is placed in its normal operational
position and is supplied at rated voltage under normal operation.
The movable part is moved backwards and forwards through the largest angle
permitted by its construction, so that the conductor is flexed.
For conductors that are flexed in normal use, flex movable part for 10 000 cycles at a
test frequency of 0,5 Hz.
For conductors that are flexed during user maintenance, flex the movable part for
100 cycles at the same frequency.
