Using the DP120 Safely Using the DP120 Application of Testing an Adjustable ® To use the differential voltage probe, do the following: In this manual a Warning identifies conditions and actions that pose Speed Drive Timing Circuit hazards to the user. Symbols used on the DP120 and in this One of the tasks of the control circuitry in an adjustable speed drive instruction sheet are explained in the next table. (ASD) is timing of the output inverter switching. The voltage waveform of the pulse width modulated (PWM) output inverter is a See explanation in Conformité series of pulses of constant magnitude (height), but varying width. manual Européenne DP120 The control circuitry manages the timing of these pulses. Double Insulation UL3111 listed Differential Voltage Probe (Protection class) Recycle Instruction Sheet Warning Introducing the DP120 Do the following to avoid electrical shock or fire if the The DP120 is a safety designed differential voltage probe for probe is connected to more than 42V peak (30V rms): floating high voltage measurements. The probe can be used on electronic high-power converters, motor speed controls, switch • Use only Fluke power adapter, model PM8907 mode power supplies, and other high voltage circuits.
