⇒ The devices are not allowed to be modified or otherwise altered in any way.

Pepperl+Fuchs GmbH is not liable for any resulting damages.

⇒ Please study the “

Technical Manual” carefully prior to starting up the devices.

⇒ The most recent version of the “Technical Manual” is always valid. It is available on the

Support page of our web site (Internet address: http://www.pepperl-fuchs.com).

⇒ The operating voltage of the devices must not exceed the limits indicated in the

"Technical Manual" under Technical data.
In the event of failure to comply, Pepperl+Fuchs GmbH is not liable for any resulting
damages.

⇒ The relevant specifications for hazardous areas (e.g. EN 50178, EN 60079,

EN 50014 - 50039) and accident prevention regulations (e.g. UVV) must be observed.

⇒ Only connect circuits to the device when the voltage of these circuits does not exceed the

values of a safety extra-low voltage (SELV) or a protective extra-low voltage (PELV).

⇒ The device must be installed and operated only in surrounding enclosures that

• comply with the requirements for surrounding enclosures according to IEC/EN
60079-0,

• are rated with the degree of protection IP54 according to IEC/EN 60529

Alternatively, it is permitted to install and operate the device in a monitored environment
that ensures a pollution degree 2 according to IEC/EN 60664-1.

⇒ The installation instructions in accordance with IE

C/EN 60079-14 must be observed.

⇒ Close all unused connections with the corresponding covers to ensure the degree of

protection

⇒ The technical data specified for the hazardous area corresponds to the certified values for

the European EEx approval. The user is responsible for ensuring that the devices are
suitable for their intended application and for the prevailing ambient conditions. No
warranty can be given by Pepperl+Fuchs GmbH in this connection.

⇒ The external power supply used for ENT-DC-30 supply must meet the overvoltage

2 Initial Operation

This description for initial operation refers to those issues that must be considered with respect to the power
supply ENT-DC. Information with respect to operation of the peripherals connected to the ENT-DC power
supply can be found in the appropriate manual.

For operation proceed as follows:

 Switch off system or machine.

 Make sure that the assembly area is non-hazardous during the initial operation in case voltages are wired or

devices will be opened that are not intrinsically safe.

 Connect Exi power supply ENT-DC. Refer to the chapter “Wiring” for the appropriate connections.

 Connect protective ground wire to the power supply ENT-DC.

Warning

The protective ground wire runs along the housing. The
housing itself must be grounded. The wire for
connecting to ground must have a cross section of at
least 2.5 mm² and should be as short as possible.

 Connect power supply.

 Verify all functions.

 Switch on system or machine.

 Verify functions of the entire system or machine.

Warning

In case the ENT-DC has not been connected correctly
or its configuration is incorrect, malfunctioning of your
system/machine is possible.

Warning

The power supply ENT-DC is exclusively designed to
be integrated into a different machine. Operation may
not be initiated until conformity of the final product with
regulation 89/336/EC and 89/392/EC has been
established and the unit has been approved by a
specialist according to EN 60079 and EN 50014
respectively.

TDOCT-4038_ENG / 2015-01 5

3 ENT-DC Power Supply

The Exi power supply ENT-DC can be used in safe areas as a power supply for components in zone 1 and
zone 2. The ENT-DC provides up to 3 feed circuits and one 20 mA CL-interface. The ENT-DC can used to feed
all hazardous components which meet the interface specifications of the ENT-DC.

3.3 Pin Assignment

For the top hat rail and full housing version of the ENT-DC-2 all connections are made in the front. For the 19"­version connections can be made in the front and in the rear. All connections can be reached from the front and
the back.
The connections X2, X3 and X4 are carried out as terminal screw-/plug-in terminals. The connection X1
constitutes a D-Sub jack. If the power supply operates with one feed circuit the connection X3 has four contacts.
If 2 or 3 feed circuits are in use the connection X3 has 8 contacts.
