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 in 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 are warnings relating to the installation and
start-up of the controller. Be sure to heed these warnings
to prevent personal injury or equipment damage.
WARNING
Depending on power module used, the circuit
powering the controller is 120–240Vac at 50/60
Hz (if a NPB-PWR-UN-H/U), 24Vac at 50/60 Hz
or 24Vdc (if a NPB-PWR-H/U), or from 100–
240Vac at 50/60 Hz (if a NPB-WPM-US/U).
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 controller’s microprocessors
and associated circuitry 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 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.
Battery Precautions
CAUTION
The optional NiMH battery used in this device
may present a risk of fire or chemical burn if
mistreated. Do not disassemble, heat above
122ºF (50ºC), or incinerate. Replace battery
pack with type NPB-BATTERY/U only. Use of
another battery may present a risk of fire or
explosion.
• Dispose of used battery promptly. Keep away
from children. Do not disassemble and do not
dispose of in fire.
• Replace external backup battery with Listed
Power Source Battery Only.
MOUNTING
Before mounting the controller, install any option card(s).
See “About Option Cards” on page 5. Also see “RS-485
Biasing” on page 11. Then mount the controller in a
location that allows clearance for wiring, servicing, and
module removal.
NOTE: This product is for indoor use only, altitude to
2,000m (6,562 ft.) maximum.
Depending on installed options, the allow-
able temperature range varies. See “Environ-
mental Requirements” below.
Avoid mounting the controller in a manner
that would make it difficult to operate the dis-
connect device. See “Physical Mounting” for
more details.
Environmental Requirements
• Do not expose the unit to ambient operating
temperatures outside the range:
0°C (32°F) to 60°C (140°F), providing the unit:
— Is not powered by the AC line input NPB-PWR-
UN-H/U module
a
, and
— The optional NiMH battery pack is not installed.
Otherwise, 0°C (32°F) to 50 (122°F) is the ambient
operating temperature range.
• Relative humidity range is 5% to 95% non-condensing.
• Pollution Degree III.
• Supply (mains) voltage requirements are as follows:
— Allowable voltage fluctuation to -15%, +10%,
Temporary overvo/- 15%.
— Transient overvoltages: Overvoltage Category II.
a
Powering the controller with the wall mount adapter
(NPB-WPM-US/U) at 60°C (140°F) is supported, how-
ever, at 60°C its output is derated 50%, i.e. 15V at 0.5A
(7.5W). No IO modules are supported.
