•
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.
