Warnings and Cautions
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.
Two Power Supply Cables
Note that some VMR series and NPS series units feature two separate power circuits,
and a separate power supply cable for each power circuit. If your VMR or NPS unit
includes two power supply cables, make certain to disconnect both power supply
cables from their power source before attempting to service or remove the unit.
Detached 15-Amp “Starter” Cable(s)
If the VMR or NPS unit includes a detached, 125 VAC, 15 Amp “Starter” Cable(s,) this
allows you to connect the VMR or NPS to power for bench testing and initial start up and
is 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.
Units with Attached Power Supply Cable(s)
For units with fixed Power Cords the socket-outlet shall be installed near the equipment
and shall be easily accessible.
