Safety notes for use in the low voltage area
Notes for personnel
WARNING:
INTERFACE Relay and
INTERFACE Cabling products must only be used
by qualified personnel (qualified electricians or
persons instructed in electrical engineering).
Phoenix Contact cannot guarantee the suitability of the
procedures or the circuit suggestions described for the
relevant application.
The products are to be classified as "not short-circuit-proof"
in case "short-circuit-proof" or "conditionally short-circuit-
proof" are not specified in the product description. For the
dimensioning of the overload protection devices take into
account the connection cross-sections and the documented
maximal continuous current (limiting continuous current).
2.3
Removing or replacing components
WARNING: Dangerous contact voltage
If live parts become freely accessible due to the
removal, replacement or absence of components
(e.g., fuses, connectors, etc.), if voltage is
present (≥ SELV/≥ 25 V AC;
≥
60 V DC) it should
be assumed that dangerous contact voltage is
present.
WARNING:
Before removing, replacing or fitting
components, disconnect the power to the
application and ensure that it cannot be switched
on again.
WARNING:
Make sure the entire application is
reassembled before switching the power back on.
If these instructions are not followed, there is a
danger of damage to health or even of a
life-threatening injury.
Observe the notes in the product-specific
documentation.
2.4
Electrostatic discharge
–
–
An electrically skilled person who because of their
training, experience and instruction, and knowledge of
relevant standards, can assess any required operations
and recognize any possible dangers. (Definition
according to DIN VDE 1000-10)
An electrically instructed person is someone who has
been instructed and, if necessary, trained by an
electrically skilled person in their required tasks and the
possible dangers caused by incorrect handling and
who has also been informed of the necessary safety
equipment, personal safety equipment and safety
measures. (Definition according to DIN VDE 1000-10)
Installation and startup
WARNING:
The power supply must be
disconnected when carrying out any work
(installation, maintenance, cleaning, etc.).
Observe the national regulations and standards.
WARNING:
During operation, this equipment
may have dangerous, live parts.
They can therefore cause considerable damage
to health or equipment, e.g., due to the
unauthorized removal of protective covers or
inadequate maintenance.
Observe the notes in the product-specific
documentation.
2.2
It is prohibited for unqualified personnel to work on the
products, on the machine or in their vicinity.
When working on the products and the system, you must
always keep the operating instructions and other items of
product documentation to hand and observe the information
therein.
The application notes and the circuit details presented in the
product-specific documentation should be understood in a
general sense and the relevant application should be tested
to see if they apply.
All items to be protected against ESD are supplied in an
ESD bag.
Only qualified personnel should pack, unpack, mount, and
remove an item while observing the ESD regulations.
NOTE: Electrostatic discharge
The device contains components that can be
damaged or destroyed by electrostatic discharge.
When handling the device, observe the
necessary safety precautions against
electrostatic discharge (ESD), according to
EN 61340-5-1 and
DIN IEC/TR 61340-5-1 VDE 300-5-2.

Installation
WARNING: Shock protection
Products with IP00 and IP20 protection
(≥ 25 V AC/≥ 60 V DC) are designed for use in a
closed control cabinet or control box
(terminal box) with IP54 protection or higher.
2.7
Overheating
WARNING:
Overheating can cause burns and
can damage the device.

Protection in case of indirect contact
If no secure separation or reinforced insulation is
available between voltages dangerous to the touch and
safety extra-low voltages you must handle the safety
extra-low voltage like a voltage dangerous to the touch.
During installation, observe any product-specific
special requirements such as the use of insulating
plates for certain voltage ranges, derating, mounting
positions, the minimum bending radius of cables, and
electrical safety, etc.
Against adjacent modules in the support rail direction at
least one functional insulation is complied with. If the
application has higher requirements of the insulation
(base or reinforced insulation), then you have to realize
these by means of suitable measures (e.g. separator
plates).
Observe the applicable directives and regulations
inside the control cabinet.
Observe the ambient temperatures and any other
special requirements (such as derating) specified in the
data sheets and package slips.
Observe the notes in the product-specific
documentation.
•
During installation, observe any product-specific
special requirements, such as derating and mounting
positions.
Provide a fuse depending on the load.
Observe the notes in the product-specific
documentation.
2.8
Grounding
A distinction is made between functional earth ground (FE)
and protective earth ground (PE). Functional earth ground is
only used to increase interference resistance. It does not
provide shock protection for people.
Protective earth ground is a low-impedance current path
that minimizes the risk to the operator in the event of an
error. Errors include high-voltage errors and/or current
errors between an electrical circuit and ground. Protective
earth ground is largely used outside the SELV area.
Protective earth grounding (PE)
Protective earth grounding protects people and machines
against hazardous voltages.
To avoid these dangers, correct installation, taking the local
conditions into account, is vital.
WARNING:
If a product has a PE connection
terminal block, this must be connected.
Observe the notes in the product-specific
documentation.

2.6
Device replacement
WARNING:
Do not replace devices while the
power is connected.
•
•
Before removing an item from or inserting an item in the
application, disconnect the power to the entire
application.
Make sure the entire application is reassembled before
switching the power back on.
Function earth grounding is used to increase resistance to
interference. Functional earth ground (FE) is only used to
discharge interference. It does not provide shock protection
for people.
For additional notes, please refer to the product-
specific data sheets and package slips.
2.9
Demands on the power supply
WARNING: Dangerous contact voltage
Only use power supply units that ensure safe
isolation between the primary and secondary
circuits according to EN 50178.
