3 About the Product
3.1 About CEDD®
CEDD®is an innovative contactless energy and communication technology. Energy and data transport are
combined in a two-wire cable system, a basestation, and contactless user points. With this structured cable
concept, lighting on airfields can easily be installed or replaced without making electrical contact with the
power or data cable.
The CEDD®system has been specifically designed for the operation of Airfield Ground Lighting (AGL)
systems on airports, with the highest possible reliability.
3.2 About the CEDD® HPS Basestation
The CEDD®HPS Basestation is a key component of the CEDD®AGL system.
The CEDD®HPS Basestation distributes energy to the CEDD®AGL LED fixtures and communicates
bidirectionally by means of the CEDD®cable. Bidirectionally means that the CEDD®HPS Basestation sends
assignments to the fixtures and the fixtures send information about their status back to the CEDD®HPS
Basestation. Each fixture is connected to the CEDD®cable without galvanic contact.
HPS means High Power System. The CEDD®HPS Basestation has been designed to supply a power up to
2.3 kW to the connected circuit.
The CEDD®HPS Basestation is typically controlled remotely but for maintenance purposes can also be
operated locally.
Refer to our website http://www.tkh-airportsolutions.com to see all the available CEDD®products.
3.2.1 Position in the CEDD® AGL System
A typical CEDD®AGL system consists of a CEDD®HPS Basestation that provides power to the CEDD®
AGL LED fixtures, and bidirectional communication to all the CEDD®AGL LED fixtures connected to the
CEDD®cable. A CEDD®HPS Terminator at the end of each CEDD®cable matches the characteristic
impedance of the CEDD®cable with the connected CEDD®AGL LED fixtures.

• Allow ample room for maintenance, panel accessibility, and cover removal.
• Protect equipment with safety devices as specified by applicable safety regulations.
• If safety devices must be removed for installation, re-install them immediately after
installation has been completed and check them for proper functioning prior to
returning power to the circuit.
• Always tighten the bolts to the recommended torque. Use a calibrated torque wrench
and apply the recommended locking agent.
• Failure to observe the above warning can cause the bolts to loosen, which will
damage and potentially loosen the equipment. This can lead to highly dangerous
situations with potentially fatal consequences.
• Condensation damages the CEDD®HPS Basestation and can cause serious injury or
death. See Acclimatization on page 17 on how to prevent condensation.
16 Installation and Maintenance Manual - CEDD®HPS Basestation
©TKH Airport Solutions 2022. All rights reserved. All specifications subject to change without notice.
5.2 Installation Requirements
5.2.1 Location Requirements
• The CEDD®HPS Basestation must be installed by qualified personnel in a restricted
access location.
A restricted access location is an area for equipment where access can only be gained:
• by qualified and authorized users
• by use of a special tool, lock and key which is controlled by the authority responsible
for the location
The CEDD®HPS Basestation must be installed in an environment meeting international requirements for
Protection rating IP-54 or better (according to IEC-60529) and pollution degree II or better (according to
IEC-61010-1). This sheltered environment must protect against water, oil, explosive vapors, smoke, dust,
salt content, corrosive substances, earthquakes, air blast, vibration, and impact.
For adequate cooling of the equipment, the recommended ambient air operating temperature in the location
is +20 °C to + 30 °C (68 °F to 86 °F).
• For safety reasons the CEDD®HPS Basestation must only be operated from a fixed
mains connection, that is, permanenty connected to the AC mains power supply.
• According to safety class 1 (IEC-61140) requirements, all parts of the cabinet and
chassis of the CEDD®HPS Basestation are connected to the protective earth
terminal of both power connectors. It is required to connect the earth terminals to the
protective earth.
• Make sure that the CEDD®HPS Basestation is properly connected to the protective
earth before connecting mains power. The CEDD®HPS Basestation is a system
with a high touch current. It is highly recommended to connect the CEDD®HPS
Basestation cabinet to the protective earth using the cabinet's protective earth
connection.
• Do not disconnect the protective earth either inside or outside of the CEDD®HPS
Basestation.
5.2.2 Acclimatization
The CEDD®HPS Basestation must be gradually acclimatized to the surrounding environment to prevent
condensation on the inside and outside surfaces of the equipment.
When the equipment is brought indoors, it must be allowed to gradually reach thermal equilibrium with the
indoor environment before removing the sealed shipping bag. If sufficient time is allowed for the hardware
to gradually acclimatize to the indoor environment, there should be no issues with long-term reliability of the
product.
Follow these guidelines to properly acclimatize the CEDD®HPS Basestation:
• Before installation store the equipment in the sealed shipping bag, preferably in the full packaging, to
minimize condensation.
• Move the equipment to the final installation location, and wait until the location requirements for
temperature and humidity are met. Do not place the equipment close to perforated tiles or other direct
sources of forced air convection.
Installation and Maintenance Manual - CEDD®HPS Basestation
©TKH Airport Solutions 2022. All rights reserved. All specifications subject to change without notice. 17
• Allow the packaged equipment to acclimatize for 24 hours. If there are visible signs of condensation after
24 hours, remove the shipping bag and acclimatize the equipment for a further 12 to 24 hours until no
visible condensation remains.
• Failure to follow these guidelines may result in serious personal injury or death and/or
damage to the CEDD®HPS Basestation.
5.2.3 Power Supply Requirements
The CEDD®HPS Basestation has two mains power supply inputs: Power AC mains and Logic AC mains.
• Power AC mains in: supplies power to the CEDD®nodes (for example LED fixtures).
• Logic AC mains in: supplies power to the control electronics.
In most operation states the Logic AC mains requires far less power than the Power AC mains. The separate
power inputs enable the installer to supply the control electronics with a low power UPS. In case of short
mains power failure or voltage dips, short downtimes of the lighting can be achieved, because the control
electronics continue operation. This may result in a lighting downtime as short as 0.5 seconds longer than
the duration of the power failure or the voltage dip.
If no UPS is applied, a short power failure may result in a restart of the control electronics. This will result in a
downtime of the lighting of 20 to 30 seconds (typically 25 seconds).
• Each power cable used for power supply to the CEDD®HPS Basestation must be
protected against overload and short circuit current by a circuit breaker. The circuit
breakers must have a nominal current of 16 A and be type B according to IEC 60898.
• The use of a disconnecting device is mandatory. This device has to simultaneously
switch and isolate the Power AC mains in and the Logic AC mains in. The neutral
contact must be made first and broken last to prevent live contacts being connected
without neutral contact. The Power AC mains in and the Logic AC mains in must have
a common neutral connection and a common protective earth connection.
• Within the power supply circuit both protective earth conductors must have equal
potential and both null conductors must have equal potential.
5.2.4 Mounting Requirements
The CEDD®HPS Basestation Printed Circuit Board Assemblies (PCBAs) are mounted inside a rugged
protecting cabinet. The operational position is vertical. The CEDD®HPS Basestation must be mounted
against a wall or on U-profiles that support all four corners of its cabinet. The wall must be able to support the
weight of the equipment (see Wall-mounting instructions).
• Use the CEDD®HPS Basestation only in the vertically mounted operating position.
Do not use the CEDD®HPS Basestation in a horizontal position as this may cause
thermal and condensation problems.
• Do not mount a CEDD®HPS Basestation vertically above another. This will adversely
affect the cooling air flow for the equipment, as the upper equipment will take in warm
air from the outlet of the lower equipment.
The CEDD®HPS Basestation must have sufficient airflow to ensure adequate cooling.
18 Installation and Maintenance Manual - CEDD®HPS Basestation
©TKH Airport Solutions 2022. All rights reserved. All specifications subject to change without notice.
Back-to-back mounting
In a back-to-back arrangement it is recommended to mount the CEDD®HPS Basestations on an H-profile
structure. This allows cool air to flow into the base of the equipment, and warm air to flow out of the top of
the equipment; the middle horizontal bar (6 in the drawing below) blocks the return of warm air from the back
of the equipment. There should be no horizontal bars blocking air flow to the top or bottom of the equipment.
Wall mounting
When mounted on a wall, minimum clearances are required (see table below). Clearance from the wall must
be created by mounting on vertical constructive profiles, leaving the space (minimum 80 mm) between the
cabinet and the wall at the top and bottom open for airflow. The cabinet should not be mounted on horizontal
profiles, which would reduce airflow around the intake and outlet.
Clearances for adequate airflow
Pos. Description Values
1 Top and bottom clearance Min. 250 mm
2 Left and right clearance Min. 100 mm
3 Distance from the wall Min. 80 mm
4 Hot air exhaust 50 mm
5 Cool air intake 90 mm
6 Airflow block Needed to prevent recirculation of warm air from
outlet to inlet
• The CEDD®HPS Basestation's cooling air intake and outlet areas must be kept free
from obstruction.

5.3 Installation Instructions
5.3.1 Wall-mounting Instructions
• The suspension materials and the structure supporting the CEDD®HPS Basestation
must be capable of supporting a weight of 80 kg.
• Ensure that the structure supporting the CEDD®HPS Basestation provides adequate
strain reliefs for all the connected cables. These are typically mounted on a mounting
plate below the cabinet.
• The rigidity of the support structure must meet the requirements of the electrical
safety standard IEC 61010-1 and applicable local regulations.
Ensure that all mounting materials are appropriate for the weight of the CEDD®HPS
Basestation and the material that it is mounted on.
The following tools are needed:
• Open ended wrench 10 mm
• Metric tap set 6 mm
• Drill with drill bit 5 mm
The example below is a guide to mounting the CEDD®HPS Basestation on a metal
structure. Other support structures may require different actions and materials.
1. Drill four holes at the distances specified in Dimensions on page 13 and tap the holes using M6 taps.
Make sure you apply the clearances required for adequate airflow; see Wall-mounting Clearances.
2. Drill holes for attaching the strain reliefs of all the connecting cables. The strain reliefs should be
mounted as close as possible to the CEDD®HPS Basestation.
