8 NETWORK CONTROLLER 3E & 6E MOUNTING AND WIRING GUIDE |
Mounting
Before mounting the controller, install any option card(s). See “About Option Cards,”
page 11. Also see “RS-485 Biasing,” page 20. 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 allowable temperature range varies.
See “Environmental Requirements” below.
Avoid mounting the controller in a manner that would make it difficult to
operate the disconnect 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 module
1
, 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 overvoltages +/- 15%.
— Transient overvoltages: Overvoltage Category II.
• If mounting inside an enclosure, that enclosure should be designed to keep the
unit within its required operating range considering a 20-watt dissipation by the
controller, plus dissipation from any other devices installed in the same enclosure.
This is especially important if the controller is mounted inside an enclosure with
other heat producing equipment.
• Do not mount the unit:
— in an area with excessive moisture, corrosive fumes, or explosive vapors.
— where vibration or shock is likely to occur.
— in a location subject to electrical noise. This includes the proximity of large
electrical contactors, electrical machinery, welding equipment, spark igniters,
and variable frequency drives.
Physical Mounting
The following information applies about physically mounting the unit.
• You can mount the controller in any orientation. It it not necessary to remove the
cover before mounting.
1. Powering the controller with the wall mount adapter (WPM-XXX) 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.
