1 SAFETY
3. Grounding (Earthing)
▪
INGVAR can be used only in electrical systems with
single Ground. User must verify before connecting
this unit to power, 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.
▪
Always use a grounded mains cable to connect the
Control Unit to the mains. Always ground INGVAR
using a separate ground cable.
4. Mains cord protective conductor
▪
INGVAR is equipped with a power cord with integral
safety ground pin.
▪
The equipment must be connected to a grounded
mains outlet.
▪
Do not defeat the safety ground in any manner.
5. Separate ground wire
▪
The INGVAR case must also be grounded by the
separate protective ground wire with connection
to the Protective Conductor Terminal on top of the
INGVAR. Check the continuity of the protective
ground wire before each use. Make sure the
connector is fastened properly to the INGVAR
Protective Conductor Terminal. Make sure the
connection point at the ground system is fastened
properly. Route the wire so that it is unlikely to be
walked on or that it may loosen accidentally by
someone or something moving near it.
▪
The protective ground wire must not be loosened
while any input connector is attached to the contacts
of a high voltage circuit breaker or another device
being subject to inductive or capacitive coupled
interference from surrounding high voltage wires.
6. Placement
▪
INGVAR must be situated away from any heat
sources such as radiators, heat registers, stoves, or
other products that produce heat.
Do not place the INGVAR in areas with excessive
dust, mechanical vibration or shock
▪
Do not use INGVAR near water.
▪
Do not expose the INGVAR to rain or moisture.
▪
Do not touch the plug with wet hands. Doing so may
result in electrical shock.
7. Use
▪
Do not use the instrument for any purpose other
than indicated by the manufacturer.
▪
Do not use any accessories/cables not recommended
by the INGVAR manufacturer as they may cause
hazards.
8. EMC Warning
▪
INGVAR can generate radio frequency energy. If not
installed and used in accordance with this manual
it may cause interference to radio communications.
INGVAR has been tested and found to comply with
the limits for measurement equipment designed
to provide reasonable protection against such
interference when used in an industrial environment.
Operation of INGVAR in a commercial or residential
area is likely to cause interference, at which case,
the user, at his own expense, will be required to take
whatever measures that may be required to correct
the interference.
9. Cables
▪
Use only approved mains detachable cable set with
INGVAR. Main supply cables shall be rated for the
maximum current for the equipment and the cable
shall meet the requirements of IEC 60227 or IEC
60245. Mains supply cables certified or approved
by a recognized testing authority are regarded as
meeting this requirement.
▪
To conform to the CE requirements for high
frequency radiation, shielded cables or cables with
added ferrite filters must be used for connection to
the inputs/outputs.
▪
Connecting cables must be routed so that they are
not likely to be walked on nor pinched by items
placed upon or against them. Do not pull on or tie
them. Pay particular attention to the connectors.
▪
To disconnect a cable, unlock the retainer (in case of
an XLR connector), grasp the connector firmly and
pull.
▪
If an input- or output cable becomes damaged, stop
using it. Use of a damaged cable may result in fire or
electric shock.
