See the Specification (Appendix A) for information on connection ratings.
5.1 Power Supply
To avoid a fire hazard from the NL-200 or the power supply consider the implica-
tions of overheating in the unlikely event of a fault in the NL200. The power dissipa-
tion in the NL-200 in a fault condition can be up to:
<Power supply voltage> * <max current delivered by power supply>
Either limit the power supply output current so that not more than 30W can be dissipated in the
NL200, or mount the unit in a fire enclosure.
Choose a PSU that limits its output current by design, by setting the current limit on the supply (if
this feature exists) or use fuses. Remember to derate the fuse, if mounted in an enclosure, as the
temperature will be higher than ambient. The external power supply will need to be able to supply at
least the average output power for all active channels.
The use of a regulated power supply with 100% short circuit protection is recommended. If however a
non-regulated power supply is used, then the maximum ripple voltage of this power supply must not
exceed 10% of the actual DC value.
Route low voltage and mains wiring separately. If they must be loomed together ensure that low volt-
age insulation rating is sufficient or that supplementary insulation is used.

1 +24V to +48V

5.2 Lighting Output
The lighting connections can exceed 46.7V but should not exceed 70V DC.
Pulse peak voltages above 46.7V are considered hazardous. The lighting
connections must be shielded from being touched along the whole length of
the cable and in the light.
Make sure you set the current or voltage rating for a light before connecting it. See the Light -
ing Setup (Section 7) for details on this.
Light output is on 4-way pluggable screw terminal sockets. It is possible to use two 2-way connectors
in a 4-way socket. Connectors LED34, LED56, LED78 are only fitted on the NL8xx models.
The lighting output connections must not be commoned or grounded in any way.
