Note on UL approval for 600 V:
The conductor entry is for field and factory wiring and meets spacing requirements for 600 V UL (Use Group C). The solder
pins are for factory wiring only. The suitability and spacing shall be evaluated in the end-use equipment, based on relevant
end-product standard.
