| Mounting the Power Supply | |
| Mount the power supply directly to the wall with #8 or #10 pan head screws. The power supply must be mounted in a wall ventilated area that allows for accessibility after installation and must not be adjacent to combustible materials or in an area that exceeds temperatures of 50°C (122°F). Mount the power supply indoors, out of the weather, and do not leave it exposed to rain or water. For outdoor or wet locations, the power supply can be enclosed inside of a raceway, inside the channel letter itself, in a UL listed for wet locations transformer box, or in a NEMA 3R box with ventilation. Some acceptable boxes for power supplies being mounted outdoors are Hoffman p/n A12R126, Westrim TC 18SO-UL or equivalent. A Class 2 power supply can also be used for outdoor or wet locations. | |
| Connecting the Primary | |
| After securely mounting the power supply, have the primary connected by a licensed electrician in accordance with local and national codes. For the 40Watt Remote Power Supply simply plug the AC power cord into a standard 3 prong grounded outlet. | |
| Connecting the Output | |
| LED power supplies have Class2 DC outputs. For reliability and performance, the following loading is not to be exceeded. | |
| Power Supply Part Number | Outputs | Input Voltage (Volts-AC) | Output Power (Watts) | Output Voltage (Volts-DC) | Maximum Output Current (Amps) |
| TR3A | 1 | 100-240 | 40 | 12 | 3.3 |
| LP1020-12 | 1 | 90-264 | 20 | 12 | 1.6 |
| LP1040-12 | 1 | 90-264 | 40 | 12 | 3.3 |
| LP1060-12 | 1 | 90-264 | 60 | 12 | 5 |
| Table 2- Power supply outlet schedule. |
It is recommended that the current be checked on each power supply output after loading is complete. The current drawn by each leg should not exceed the current rating on the power supply label. If the measured current does exceed the rated current, reduce the nuber of LED modules on that leg until the current is below the rated output. The total number of modules per power supply is not to exceed the schedule as shown in Table 1.
|
| Routing Secondary Wires |
| When wiring the secondary outputs of the power supply, all routing through walls must be sealed with outdoor rated caulk to protect the sign and building from water damage and the cable from chafing. The power supply leads and letter-to-letter jumpers can be routed through walls, inside and outside without conduit. It is recommended that all connections be enclosed in a UL listed junction box with strain relief. |
| Extension of Power Supply Leads |
| If a longer lead wire from the power supply to the modules is needed, an extension can be used. The extension should be kept as short as possible (under 15 feet for 18 AWG UL listed, or under 50 feet for 14 AWG UL listed.) |
| WARNING: CHECK POLARITY |
| After all wiring is complete and the lighting modules are connected to the power supply, RECHECK THE POLARITY OF ALL CONNECTIONS. Reverse polarity connections may damage the LED modules and voids the product of warranty. |
