訂貨須知 Order note
1. 用戶需延時1-5min產品出廠整定為5min；需延時6-10min產品出廠整定為10min。如需延時10min以上產品訂貨時請注明。
2. 額定電壓如有特殊要求請注明。
例：若需訂購立式安裝的DED51-LED防爆視孔燈，額定電壓為AC110。由燈體開關控制延時5min關斷，則訂貨型號為DED51-LED-AC110/B5L。
1.  Factory default for products with time delay 1-5min is set as 5min; for products with time delay 6-10min is set as 10min. Please specify clearly if require the time delay more than 10min.
2. Please specify clearly for special requirements on rated voltage.    e.g: if need a vertically installed DED51-LED explosion-proof inspection hole lamp, rated voltage is AC110, with lamp body switch control, turn off after a delay of 5min, then the order model should be DED51-LED-AC110/B5L.
