2.2 Safety instructions
1.
Single ground system
- This equipment can
be used only in electrical systems with single
ground. Before connecting this unit to power
you must verify that High Voltage Ground
and Low Voltage Protective Ground create a
single protective ground with no measurable
voltage potential existing between these ground
systems. If a voltage potential is found between
the ground systems please consult local safety
regulations.
2.
Mains cord protective conductor
- The
instrument is equipped with a power cord with
integral safety ground pin. Do not defeat the
safety ground in any manner. The equipment
must be connected to a grounded mains outlet.
3.
Ground lead
- The first connection made, and
last removed is the connection of instrument
Protective conductor terminal to station ground
using the separate ground lead.
Make sure ground lead is checked for continuity
and securely fastened.
4.
Use an easily accessible power outlet
- This
will ensure that you can disconnect the power
quickly in case of a problem. The instrument
should be operated only from the type of power
source indicated on its nameplate.
5.
Connecting
- It is very important not to
connect any leads on top of or too close to
one another. Take the necessary precautions
to as-sure one lead falling off will not take a
second lead with it. Never connect the test
equipment to energized equipment. Never make
any connection or disconnections while the test
equipment is generating or discharging.
6.
Testing
- When applying current to a
transformer with very high inductance,
additional care should be taken not to remove
current leads while current is still flowing.
Removal of terminals while current flowing
may generate an arc that may result in lethal
injury: electrical, thermal or by fall. Ensure that
the transformer to be tested is completely de-
energized. check every winding. Ensure that all
terminals of the transformer are disconnected
from line or load at the transformer.
connections to ground may be left in place.
