8 WM Eco-POWER METER NOTES. Avoid ocations subject to fammabe or corrosive gases, excessive dust, oi, vibrations, or excessive shocs.. Athough the case is made from fireproof resin, do not mount it next to fammabe materias. Aso, avoid pacing it directy on top of materias that catch fire easiy.. f the operating power suppy surge exceeds the foowing vaue, the interna circuit coud be destroyed, so be sure to use a surge absorption eement. Surge votage,000v Standard surge waveform The vaues in the graph right are the surge-votage resistance at ±(. 0)µs of singe-poarity fu-wave votage. Surge wave form [±(. 0) µs uni-poar fu wave votage] Externa noise of up to the eve shown beow is treated as noise votage, but eves higher than this coud ead to mafunctioning or damage to the interna circuit.
