➔Before performing visual inspections, tests, or maintenance on this equipment, disconnect all sources
of electric power. Assume that all circuits are live until they have been completely de-energized,
tested, and tagged. Pay particular attention to the design of the power system. Consider all sources of
power, including the possibility of backfeeding.
➔Turn off all power supplying the ZDI and the area in which it is installed before working on it.
➔Always use a properly rated voltage sensing device to confirm that all power is off.
➔Before closing all covers and doors, inspect the work area for tools and objects that may have been
left inside the equipment or panel.
➔When removing or installing metering or other equipment, do not allow it to extend into an energised
bus.
➔The successful operation of this equipment depends upon proper handling,
➔Neglecting fundamental installation requirements may lead to personal injury as well as damage to
electrical equipment or other property.
➔Before performing Dielectric (Hi-Pot) or Megger testing on any equipment in which the energy meter
is installed, disconnect all input and output wires to the ZDI.
➔High voltage testing may damage electronic components contained in the ZDI.
➔Failure to follow these instructions will result in death or serious injury.
➔EpiSensor equipment should be installed, operated, serviced and maintained only by qualified
personnel. EpiSensor does not assume any responsibility for any consequences arising out of the use
of this equipment.
➔Fuse for neutral terminal is required if the source neutral connection is not grounded.
➔Clearly label the device’s disconnect circuit mechanism and install it within easy reach of the operator.
➔The fuses / circuit breakers must be rated for the installation voltage and sized for the available fault
current.
