
Personnel using heart pacemakers should obtain expert advice on the
possible risks
before operating this equipment or being close to the
equipment during operation.
Safety in Using the SG System
Never assume that either the SG32-1500M High Voltage Output Cable or
the Cable Specimen is de-energized. Always treat exposed conductors and
connections as potential electric shock hazards.
The SG32-1500M and the Cable under test are both sources of
instantaneously lethal levels of electrical energy.
 Do not use this equipment to locate faults on any cable that may be close
enough to an energized cable to allow a burn-through of the insulation of
the energized cable.

Do not operate the SG unit if it has not first been stabilized and in an
upright position.

Remain a safe distance from all parts of the High-Voltage circuit, including
all connections, unless the equipment is de-energised and all parts of the test
circuit are earthed/grounded. Be aware that any voltage applied to the Cable
Specimen will be present at the remote end(s) and at any other exposed part
of the cable, often out of sight of the operator.

Use the grounding and connection procedures. If other manufacturers'
equipment is used with the SG unit, the user is responsible for verifying that
the grounding and interconnections between the systems comply with each
Manufacturer's Instructions.

Use Industry Accepted practices for making reliable, low-impedance
connections, capable of carrying large surge currents.

Maintain adequate air clearances between the exposed High-Voltage
conductor and any adjacent grounds to prevent spark-over. An uncontrolled
spark-over can create a safety hazard.

Megger recommends the use of appropriately rated rubber gloves when
connecting and disconnecting to High-Voltage terminals.
 An Interlock circuit is provided (and its use is highly recommended) to
enable the operator to safely control access to the complete high-voltage
circuit.
