2.1 Mounting
The support structure needs to be sturdy enough to support the weight of the light bars and any ad-
ditional equipment. The power cord cannot be used to support the weight of the unit.
Air must be able to ow freely around the SIERA light bar and power supply unit, they are cooled using
passive, convection cooling.
The SIERA heat sink is designed to support your chosen bracket or standard DIN M6 screw/bolt (or
local equivalent), by way of the T-slot, to attach to your shelving unit
Once mounted verify that it is secure and hanging at the recommended mounting height.
2. Installation

2.2 Connecting light bars to
the power supply unit
Your SIERA light bars need to be connected to the SIERA power supply unit with the power cables
provided in the SIERA power supply unit box. The illustrations below illustrate how to remove the
protective caps that come on the ports and then attach the cables. If some of the ports are not in use,
please replace the cap on it to prevent moisture entering the power supply unit.
The SIERA power supply unit has four ports. The SIERA light bar should be connected in series.
No more than ve SIERA light bars can be connected to each connection port and no more than
twelve, in total, can be connected to the SIERA power supply unit.
The status LED indicator on the front of the SIERA power supply unit will change from green to red
if there is an issue e.g. if you attach too many bars to the power supply, or to any of the connection
ports. To resolve this, disconnect the SIERA power supply unit from the main power source and
remove the extra light bars, before turning it back on.
Do not attach the light bars when the power supply unit is turned on, if you do this the
SIERA power supply unit may shut down to protect itself. If this happens disconnect from
the mains power and then re-connect to reboot the power supply unit.

2.3 Electrical installation
Heliospectra AB requires that the electrical installation is conducted by a locally licensed
electrician or electrical engineer and completed according to local electrical standards.
The SIERA power supply unit runs on the main power voltage between 100 and 240 VAC, depending
on your country’s specic standard.
The SIERA power supply unit is delivered with a power cable (three wires; one blue neutral, one brown
live and one yellow and green ground) with an in-line connector on the end. Your electrician can use
this connector to attach the power supply unit to a mains power cable in the most suitable and safest
way.
The second cable coming from the SIERA power supply unit includes two wires (brown + and
blue - ), this is a 0-10V dimming control signal input. The cable comes with an in-line connector on the
end for simple connection to your chosen dimming solution. What dimming solutions supported and
how to connect them are described on the next page.
NOTE!
Only use the SIERA power supply unit to power the SIERA light bars.
Any unauthorized connections to other systems could damage or signicantly reduce
the lifespan of the products.

2.4 Surge protection
Heliospectra AB requires that the xtures are installed with adequate surge protection according to
the local recommended practice. In North America IEEE 1100-2005 contains the recommended prac-
tice for powering and grounding electronic equipment. In Europe the applicable standard is IEC 62305
– Protection Against Lightning. If you are outside of North America or Europe please use your local
standard.
All installations should utilize surge protection devices (SPDs), to provide maximum protection
regardless of the source of the surge. The three zones include:
• The rst zone is at the service entrance where the most robust SPD is placed to divert surges com-
ing from external sources such as lightning. SPDs installed here are listed as Type-1, SPD devices.
• The second zone of protection is within the facility at locations identied as susceptible to surges.
SPDs at these locations are listed as Type-2, SPD devices and are installed on equipment such as
switchboards, panel-boards, motor-control centers.
• The third zone of protection is at the outlet or point of use. SPDs installed here are listed as Type-3,
SPD devices.
It is strongly recommended that a professional engineer, experienced with surge suppression tech-
nology, be retained to design the protection system for your facility to ensure all SPDs are properly
sized and coordinated.

4. Maintenance
4.1 Cleaning
To ensure optimal performance and lifespan of the lamp it is important to clean regularly. If you see a
build up of dirt or residue anywhere on the SIERA lamp, this needs to be cleaned.
To clean the SIERA most effectively please follow these simple steps.
1. Make sure the xture is turned off and not connected to the mains power.
2. Light dust and dirt can be cleaned with low-pressure compressed air.
3. More heavily polluted xtures could be cleaned with a soft cloth using water and soap.
4. Wipe everything dry, or let the xture dry fully by itself before reconnected to the mains
power.
DO NOT (!) disassemble the SIERA light bar or SIERA power supply unit in order to clean it,
disassembling them will invalidate your warranty.
The SIERA light bars are static spectrum xtures. You can use a dimmer, attached to the signal cable
on the power supply unit, to control the intensity of light emitted.
The xture can be connected to a timer, to set the photo-period which the xtures are to be active
within.

6.2 Terms and Conditions
Heliospectra requires that the installation of the Product is conducted by a licensed electrician with
adequate surge protection according to the requirements below. If the surge protection requirement
is not implemented, a proof of electrical quality reading must be performed by a third party and pre-
sented as proof of adequate electrical quality.
6.2.1 Electrical Installation Quality
Requirements and Conditions
Heliospectra does not give any warranty for third party software (meaning herein software created by
other parties than Heliospectra) and Heliospectra shall not be liable for any damages possibly caused
by failures in third party software or caused by changes in the software by the Buyer or anyone other
than an authorized Heliospectra technician.

6.2.2 Surge Protection Requirements
NORTH AMERICA
Heliospectra requires that Products are installed with adequate surge protection according to the
IEEE 1100-2005 recommended practice for Powering and Grounding Electronic Equipment. Consid-
ering that surges can originate from both internal and external sources, surge protection devices
(“SPDs”) are to be installed to provide maximum protection regardless of the source location. The
three zones include:
• The rst zone is at the service entrance where the most robust SPD is placed to divert
surges coming from external sources such as lightning. SPDs installed here are listed as Type-1,
SPD devices.
• The second zone of protection is within the facility at locations identied as susceptible to surg
es. SPDs at these locations are listed as Type-2, SPD devices and are installed on equipment
such as switchboards, panelboards, motor-control centers.
• The third zone of protection is at the outlet or point of use. SPDs installed here are listed as Type-3,
SPD devices.

6.2.3 Warranty Limitations
EUROPE
Heliospectra requires that all xtures should be protected by adequate surge protection, in accor-
dance with the following standard: IEC 62305 – Protection Against Lightning.
This standard stipulates the following:
• PDs (Surge Protection Devices) should be installed when crossing from one lightning protection
zone to another
• Lighting is not the only threat; switching of loads, which are more frequent than lightning
strikes, also create high voltage transients that can damage electrical or electronic equipment
over time.
• Risk assessments are required to be carried out to assess the requirements of any building
for SPDs.
• Ensure that the 3 Lightning Protection Zones (LPZ) zones and types 1, 2, 3 of Surge Protection
Devices are used correctly.
For other installation locations, please advise local electrical standards that are equivalent.
