Power Supply
Do not power up the EM20-85 until it is properly connected. Be sure the power is cut off before connecting a cable to or
disconnecting a cable from the host interface connector. Hot-plugging could damage the engine.
Unstable power supply or sharp voltage drops or unreasonably short interval between power-ons may lead to unstable
performance of the engine. Do not resupply the power immediately after cutting it off.
