Safety requirement EN ⚫ Operating: Below +30°C: ≤ 95%RH (without condensation) +30°C to +40°C: ≤ 75%RH (without condensation) ⚫ Non-operating: +40°C to +50°C: ≤ 45%RH (without condensation) Below 65°C: ≤ 95% RH (without condensation) Warning: To avoid short circuit or electric shock, do not operate the device in a damp environment. Altitude Operating: below 3 km Non-operating: below 15 km Installation (Overvoltage) Category This product is powered by mains conforming to installation (overvoltage) category II. Warning: Ensure that no overvoltage (e.g. from lightning) reaches the product. Otherwise, the operator may be in danger of receiving electric shock.
Installation (Overvoltage) Category Definitions Installation (overvoltage) category I refers to signal level which is applicable to equipment measurement terminals connected to the source circuit. Among these terminals, precautions are done to limit the transient voltage to a low level. Installation (overvoltage) category II refers to the local power distribution level which is applicable to equipment connected to the AC line (AC power). Pollution Degree Pollution Degree 2 Pollution Degree Definition ⚫ Pollution Degree 1: No pollution or only dry, nonconductive pollution occurs. The pollution has no effect. For example, a clean room or air-conditioned office ⚫ Pollution Degree 2:
Normally only nonconductive pollution occurs. Temporary environment. conductivity caused by condensation is to be expected. For example, indoor environment. ⚫ Pollution Degree 3: Conductive pollution or dry nonconductive pollution that becomes conductive due to condensation occurs. To be found in industrial environment or construction sites (harsh environments). For example, sheltered outdoor environment. ⚫ Pollution Degree 4: The pollution generates persistent conductivity caused by DPO7000 Quick Guide Copyright © Qingdao Hantek Electronic Co., LTD 4
