sure trouble-free operation of the device and protection of persons and
material. It is therefore of utmost importance to observe and compliance
with these regulations.
If these are not complied with, then no claims may be made under the
terms of the warranty. No liability will be assumed for any ensuing dam-
age.
Safety of the device
This device has been manufactured in accordance with the latest techno-
logical standards and approved safety regulations
The device should only be put into operation by trained and qualified staff.
Care must be taken that all cable connections are laid and fixed in position
correctly. The device should only be operated with the voltage supply in-
dicated on the identification label.
The device should only be operated by qualified staff or employees who
have received specific instruction.
If a device must be opened for repair, this should only be carried out by
employees with appropriate qualifications or by hopf Elektronik GmbH.
Before a device is opened or a fuse is changed all power supplies must
be disconnected.
If there are reasons to believe that the operational safety can no longer
be guaranteed the device must be taken out of service and labelled ac-
cordingly.
The safety may be impaired when the device does not operate properly
or if it is obviously damaged.
CE-Conformity
This device fulfils the requirements of the EU directive 2014/30/EU "Electro-
magnetic Compatibility" and 2014/35/EU "Low Voltage Equipment".

1 Network Clock Device 8030HEPTA/NCD
The Network Clock Device 8030HEPTA/NCD consists of a Network Time Client 8030NTC and
a Network Time Server 8030NTS/M. Module 8030NTC acts as time source for the application,
module 8030NTS/M as NTP Stratum 1 Server or as PTP Grandmaster.
Module 8030NTC supports the following network protocols as synchronization source:
•NTP (incl. SNTP)
•IEEE 1588 Precision Time Protocol (PTP) (Activation Key required)
Module 8030NTS/M can output the following network protocols:
•NTP (incl. SNTP)
•Daytime
•Time
•SINEC H1 time datagram (Activation Key necessary)
•IEEE 1588 Precision Time Protocol (PTP) (Activation Key necessary)
Front Side
Rear Side
The Network Clock Device 8030HEPTA/NCD is integrated into a 1U/84HP 19" rack and char-
acterized by its easy and simple operation. Some of these practice-oriented functionalities are
e.g.:
•Complete parameterisation via protected WebGUI access
All required settings for operation can be executed via a password protected WebGUI.
•LCD-Display and Status-LEDs in the front panel
The LCD-Display and the Status-LEDs make rapidly and easily substantial information
for commissioning, on the operating status and for support matters available if a prob-
lem occurs, even without WebGUI access.
•Automatic switch-over of summer/winter time (initial setting required)
After initial commissioning there is no user intervention for a correct summer/winter
time changeover for the following years required.
•Automatic handling of the leap second
In case of announcing a leap second via the sync source of Network Clock Device
8030NTS/NCD, this leap second will automatically be inserted.
•Customized extensions possible
The new designed housing concept allows customized system extensions for addi-
tional signal outputs (processed ex-works) easily and fast.
