Safety Precautions
The following items are warnings of a safety nature relating to the installation and start-up of the NXS controller. Be
sure to heed these warnings to prevent personal injury or equipment damage.
A 120Vac or 240Vac circuit powers the 24Vdc module (Power Supply) powering the NXS.
Warning •
Disconnect power before installation or servicing to prevent electrical shock or equipment
damage.
Make all connections in accordance with national and local electrical codes. Use copper
•
conductors only.
To reduce the risk of fire or electrical shock, install in a controlled environment relatively free
•
of contaminants.
This device is only intended for use as a monitoring and control device. To prevent data loss or
•
equipment damage, do not use it for any other purpose.
Static Discharge Precautions
Static charges produce voltages high enough to damage electronic components. The microprocessors and
associated circuitry within a NXS controller are sensitive to static discharge. The following items are cautionary notes
that will help prevent equipment damage or loss of data caused by static discharge.
Work in a static-free area.
Caution •
Discharge any static electricity you may have accumulated. Discharge static electricity by
•
touching a known, securely grounded object.
Do not handle printed circuit boards (PCBs) without proper protection against static discharge.
•
Use a wrist strap when handling PCBs. The wrist strap clamp must be secured to earth ground.
General Precautions
Do not install any expansion options (memory, PC/104 modules) apart from those already in the device,
