Instruction manual

CI-ControlWaveLP Installation / 2-3
- The rear of the ControlWaveLP’s Mounting Plate must mount to the selected
enclosure’s backplate.
- The unit must be positioned so that the front of the assembly (exposed side of MFI/OB
Board) is visible and the unit is accessible for service, i.e., installation of an option or
replacement of the RAM Battery, Fuse or a PCB.
2.2.1 Temperature & Humidity Limits
The ControlWaveLP is designed to operate over a -40 to +158 °F (-40 to +70 °C)
temperature range and a 0% to 95% Relative Humidity range. Make sure that the ambient
temperature and humidity at the measuring site remains within these limits. Operation
beyond these ranges could cause output errors and erratic performance. Prolonged
operation under extreme conditions could also result in failure of the unit.
2.2.2 Vibration Limits
Check the mounted enclosure for mechanical vibrations. Make sure that the ControlWave-
LP is not exposed to a level of vibration that exceeds those given in the specifications. The
ControlWaveLP’s vibration limits are 1g for 10 - 150 Hz & .5g for 150 - 2000 Hz.
2.2.3 ControlWaveLP Grounding
A # 14 AWG ground wire must be run from the ControlWaveLP’s PSSM Terminal TB2-3
(Chassis Ground) to a known good Earth Ground (see Figure 2-3). In lieu of a direct
connection to Earth Ground, it is recommended that the unit’s Chassis Ground Terminal be
connected to a conductive mounting panel or plate, a user supplied Ground Lug or a user
supplied Ground Bus. The panel, lug or bus in turn must be connected to a known good
Earth Ground via a #4 AWG wire.
The following considerations are provided for the installation of the ControlWaveLP
system ground:
• Ground Lug, Ground Bus or Mounting Panel/Plate to Earth Ground wire size should be
#4 AWG. It is recommended that stranded copper wire is used and that the length should
be as short as possible.
• This ground wire should be clamped or brazed to the Ground Bed Conductor (that is
typically a stranded copper AWG 0000 cable installed vertically or horizontally).
• The wire ends should be tinned with solder prior to insertion into the Chassis Ground
Lug. Note: Use a high wattage Soldering Iron.
• The ground wire should be run such that any routing bend in the cable has a minimum
radius of 12-inches below ground and 8-inches above ground.
