wiring the NSO, follow the guidelines below.
Don’t do this Do this
Don’t make sharp bends in the cables Do make drip and service loops
Don’t run cables in a way that allows water
to fl ow down into the connectors
Do tie-wrap all cables to keep them secure
Don’t route the data cables in areas adja-
cent to radar, transmitter, or large current
carrying cables
If cables are shortened, lengthened, or re-
terminated, do seal and protect all wiring
connections
Do leave room at the back to install and
remove cables
Before starting the installation, be sure to turn electrical power off. If power
is left on or turned on during the installation, fi re, electrical shock, or other
serious injury may occur. Be sure that the voltage of the power supply is
compatible with the system
The NSO has a voltage rating of 12 V DC or 24 V DC. (9 V DC - 32 V DC max
range). SimNet is 12 V DC only
The red wire should always be connected to (+) DC V using a fuse or thermal
breaker (10 Amp)
