Safety Information
DANGER
HAZARD OF ELECTRIC SHOCK,
EXPLOSION, OR ARC FLASH
· This product must be installed inside a
suitable fire and electrical enclosure.
· Follow safe electrical work practices. See
NFPA 70E in the USA, or applicable local
codes.
· This equipment must only be installed and
serviced by qualified electrical personnel.
· Do not use this product for life or safety
applications.
· Do not install this product in hazardous or
classified locations.
· Read, understand and follow the instructions
before installing this product.
· Turn off all power supplying equipment
before working on or inside the equipment.
· Product may use multiple voltage/power
sources. Disconnect ALL sources before
servicing.
· Use a properly rated voltage sensing device
to confirm that power is off. DO NOT depend
on this product for voltage indication.
· Current transformer secondaries (current
mode) must be shorted or connected to a
burden at all times.
· Products rated only for basic insulation must
be installed on insulated conductors.
· Replace all doors, covers and protective
devices before powering the equipment.
· The installer is responsible for conformance
to all applicable codes.
Failure to follow these instructions will result in
death or serious injury.
A qualified person is one who has skills and know-
ledge related to the construction and operation of
this electrical equipment and installations, and has
received safety training to recognize and avoid the
hazards involved. NEC Article 100
If this product is used in a manner not specified by
the manufacturer, the protection provided by the
product may be impaired. No responsibility is as-
sumed by the manufacturer for any consequences
arising out of the use of this material.
Provide a disconnect device to disconnect the
meter from the supply source. Place this device
in close proximity to the equipment and within
easy reach of the operator, and mark it as the
disconnecting device. The disconnecting device
shall meet the relevant requirements of IEC 60947-
1 and IEC 60947-3 and shall be suitable for the
application. In the US and Canada, disconnecting
fuse holders can be used. Provide overcurrent
protection and disconnecting device for supply
conductors with approved current limiting devices
suitable for protecting the wiring.
Control system design must consider the potential
failure modes of control paths and, for certain criti-
cal control functions, provide a means to achieve a
safe state during and after a path failure.
Examples of critical control functions are emergen-
cy stop and over-travel stop.
For Janitza measurement devices and compo-
nents, use
only
current transformers intended for
measuring purposes (“transformers”)!
“Transformers”, unlike “protection transformers”,
go into saturation at high current peaks. “Pro-
tection transformers” do not have this saturation
behavior and can therefore significantly exceed
the rated values in the secondary circuit. This can
overload the current measurement inputs of the
measurement devices!
Furthermore, please note that Janitza measure-
ment devices and components are
not
to be
used for critical switching, control or protection
applications (protective relays)! Observe the safety
and warning information in the “Installation” and
“Product safety” chapters!
WARNING
LOSS OF CONTROL
·
Assure that the system will reach a safe state
during and after a control path failure.
·
Separate or redundant control paths must be
provided for critical control functions.
·
Test the effect of transmission delays or
failures of communication links.
1
·
Each implementation of equipment using
communication links must be individually and
thoroughly tested for proper operation before
placing it in service.
Failure to follow these instructions may cause
injury, death or equipment damage.

For additional information about anticipated
transmission delays or failures of the link, refer to
NEMA ICS 1.1 (latest edition). Safety Guidelines
for the Application, Installation, and Maintenance
of Solid-State Controls or its equivalent in your
specific country, language, and/or location.
