INSTALLATION GUIDE-GENERATION 2 INVIZILITE
The information in this section will help you determine the design and layout of the Invizilite Generation 2 Low-Voltage Lighting System.
Operating Temperatures
As with every lighting system, the Invizilite Generation 2 will generate heat during operation. Sufficient ventilation is required to dissipate the heat generated during operation. The Invizilite Generation 2 system is not intended to be installed in area where air flow is restricted. The surface the Invizilite Generation 2 is mounted to must not exceed 90 degree C (194 degree F).
Low Voltage Transformers
A low voltage transformer is required to power the Invizilite Generation 2 system. There are two types of low voltage transformers: electronic and magnetic. To guarantee safety, always use a UL listed or UL recognized transformer.
Electronic Transformers
Electronic transformers have smaller profiles than magnetic transformers. They are available in sized with single outputs of 60-300 watts. Transformers have short circuit and auto-reset thermal cut-off protection at 125 degree C. Electronic transformers may cause RFI (Radio Frequency Interference). If RFI is present, reposition the transformer by rotating it (plug it in the opposite way) changing the direction of the magnetic field. RFI can be eliminated by using a magnetic transformer which does not cause RFI.
Magnetic Transformers
Magnetic transformers are typically larger and weigh more than an electronic transformer. They are available in 300watt or 600watt, Toroidal or E.I. lamination. The 12volt transformers have four multi taps 12, 13, 14, 15 or 24, 26, 28, 30 for the 24volt models. These magnetic transformers have an auto reset in-line primary overload protection and an in-line secondary magnetic breaker to protect against short circuit. All of our magnetic transformers may be loaded up to 100% when mounted horizontally.
Dimming Transformers
Invizilite Generation 2 may be dimmed. When dimming this system, it is recommended that the dimmer be installed on the line voltage (primary) side of the transformer. When using a magnetic transformer, it is recommended to use a low voltage dimmer suitable for use with a magnetic transformer. When using an electronic transformer, it is recommended that you use a low voltage electronic dimmer.
Switching
For installations that require switching on the low voltage (secondary) side, it is important that the switch being uses is rated for the amperage that the Invizilite Generation 2 system is drawing through it. You can calculate amperage using the following equation: Amps (amperage) = Total Watts divided by Voltage. If there is confusion about which switch to use, use a switch with a minimum rating of 25amps and this will cover the maximum rating of the Invizilite Generation 2 system.
Transformer Placement
Transformers should be placed as close as possible to the start of the Invizilite Generation 2 run to help compensate the voltage drop that may occur. Electronic transformers are more susceptible to voltage drop and it is recommended that electronic transformers are not used for long runs or used in a remote mounting application.
Remote Mounting Transformers
When remote mounting a magnetic transformer, it is important to select the correct wire gauge for use between the transformer and the beginning of the Invizilite Generation 2 runs. Use the chart below to establish the correct wire gauge.
Voltage Drop
When the first lamp in the run is brighter than the last lamp in the run, this difference is known as voltage drop. Voltage drop can be minimized by selecting the correct wire gauge between the remove transformer and the start of the run.
Reducing Voltage Drop
1. Use a multi-tap transformer.
2. Use the correct gauge wire from transformer to the start of the run.
3. Place the power feed in the center of the run.
