Installation
The installation of the Network Clock Device 8030HEPTA/NCD is described below.
5.1
Network Clock Device 8030HEPTA/NCD in 1U Housing
5.1.1 Installation of the 19 Inch Rack
The System is assembled in a 1U/84HP 19" housing for control cabinet installation (measure-
ment see
Chapter 2.1 19 inch Rack 1U/84HP (Slim Line)
).
The following steps are to be carried out:
•
Place the rack in the control panel and fix to the mounting brackets on the front side of
the rack using 4 screws.
The side ventilation apertures on the right and left hand sides must not
be covered. Otherwise ventilation will not be effective and lack of con-
vection and / or thermal coupling with surrounding equipment may give
rise to an excessive equipment operating temperature.
•
Ensure that there is sufficient space between the back of the rack and the control panel
to allow connection and data lines with the system
5.1.2 Earthing
The Network Clock Device 8030HEPTA/NCD is usually earthed via the PE cable of the power
supply.
An additional earth cable for surge protection purposes can be connected by means of the
earth screw located on the rear side of the System housing.
5.1.3 AC Power Supply
The Systems’ standard AC power supply unit is described here. However, the connection data
on the nameplate of the respective unit is always applicable.
Attention should be paid to the following when connecting the power supply:
•
Correct voltage type (AC or DC)
•
Voltage level
The power feed is via an input connector with EMI filter compliant with IEC/EN 60320-1/C14
I O
•
Check that the mains power switch is in position "
0
" (= off).
•
Plug the input connector into the System’s mains
power inlet.
•
Connect the input connector to the mains power
supply and switch the line circuit breaker on.
The Network Clock Device 8030HEPTA/NCD can be damaged if incorrect
voltage is connected.
