UL1741. If a ground fault occurs, the inverter will disconnect and will not
restart until the fault has been cleared.

GROUNDING THE AC CIRCUIT

A Protective Earth (PE) feedthrough terminal block is available in the AC connection
area. The gauge of the AC grounding conductor must be sized in accordance with
Table 250.122 of the NEC.
• Establish an AC ground connection at no more than one of the GND marked
terminals before connecting to the grid.

Heat Hazard

The AE 3TL cabinet surface and heat sink can reach temperatures up to 75°C
(167°F).
WARNING:
Risk of burn. The inverter components can become extremely hot during
normal operation. Use caution when working around the heat sink area.
AVERTISSEMENT:
Risque de brulure. Certaines parties de l'onduleur peuvent atteindre des
températures considérables durant une exploitation normale. Soyez prudent
durant les travaux autour du puits thermique.
