Installation Instructions
Secure Racking
If Secure Racked units are installed in a closed or multi-unit rack assembly, they may
require further evaluation by Certification Agencies. The following items must be
considered.
1. The ambient within the rack may be greater than room ambient. Installation
should be such that the amount of air flow required for safe operation is not
compromised. The maximum temperature for the equipment in this environment is
60°C. Consideration should be given to the maximum rated ambient.
2. Installation should be such that a hazardous stability condition is not achieved due
to uneven loading.
Input Supply
Check nameplate ratings to assure there is no overloading of supply circuits that could
have an effect on overcurrent protection and supply wiring.
Grounding
Reliable earthing of this equipment must be maintained. Particular attention should
be given to supply connections when connecting to power strips, rather than direct
connections to the branch circuit.
No Serviceable Parts Inside; Authorized Service Personnel Only
Do not attempt to repair or service this device yourself. Internal components must be
serviced by authorized personnel only.

• LithiumBattery
CAUTION:Dangerofexplosionifbatteryisincorrectlyreplaced.Replace
onlywithsameorequivalenttyperecommendedbythemanufacturer.
Discardusedbatteriesaccordingtothemanufacturer'sinstructions.
Disconnect Power
If any of the following events are noted, immediately disconnect the unit from the outlet
and contact qualified service personnel:
1. If the power cord becomes frayed or damaged.
2. If liquid has been spilled into the device or if the device has been exposed to rain
or water.

ii
Warnings and Cautions
Two Power Supply Cables
Note that some NPS series units feature two separate power inlets and a separate
power supply cable for each power inlet. Make certain to disconnect all power supply
cables from their power source before attempting to service or remove the unit.
15 Amp Starter Cable(s)
Depending on your specific model, some NPS Series units may be shipped with either
one or two 125 VAC, 15 Amp "Starter" Cables. These Starter Cables will allow you to
connect the NPS to power for bench testing and initial start up and are adequate for
applications that only require 15 Amps. For 20-Amp power switching applications,
please refer to the WTI Power Cable guide supplied with the unit, or use appropriate
20-Amp cables.
