订货须知 Order note
1. 用户需延时1-5min产品出厂整定为5min；需延时6-10min产品出厂整定为10min。如需延时10min以上产品订货时请注明。
2. 额定电压如有特殊要求请注明。
例：若需订购立式安装的DED51-LED防爆视孔灯，额定电压为AC110。由灯体开关控制延时5min关断，则订货型号为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.
