Precautions
This document uses the following warning and caution conventions:
Caution
Cautions remind the reader to be careful. They alert readers to situations where there is a chance
that the reader might perform an action that cannot be undone, might receive unexpected results, or
might lose data. Cautions contain an explanation of why the action is potentially problematic.
Warning
Warnings alert the reader to proceed with extreme care. They alert readers to situations where there
is a chance that the reader might do something that can result in personal injury or equipment
damage. Warnings contain an explanation of why the action is potentially dangerous.
Safety Precautions
The following items are warnings of a general nature relating to the installation and start-up of the T-600
controller. Be sure to heed these warnings to prevent personal injury or equipment damage.
Warning
•
Depending on power module used, the circuit powering the T-600 is 90–263Vac at 50/60 Hz (if
using NPB-PWR-UN), 24Vac at 50/60 Hz or 24Vdc (if using NPB-PWR), or from 100–240Vac
at 50/60 Hz (if using WPM-
XXX
). 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 T-600 controller are sensitive to static discharge. Follow these precautions when
installing, servicing, or operating the system:
Caution
•
Work in a static-free area
.
•
Discharge any static electricity you may have accumulated. Discharge static electricity by
touching a known, securely grounded object.
•
Do not handle the printed circuit board (PCB) without proper protection against static discharge.
Use a wrist strap when handling PCBs. The wrist strap clamp must be secured to earth ground.
