Emerson ControlWave - Power Supply;Sequencer Module (PSSM)

ControlWave Instruction Manual (CI-ControlWave)
Revised Nov-2010 Installation 2-7
Note: After you install the PSSM in the housing, as an added
precaution we recommend that you run a #14 AWG wire from
the TB2-5 power connection (chassis ground) to the same known
good earth ground.
Additional grounding guidelines include:
 Use stranded copper wire (#4 AWG) for the housing to earth
ground, and keep the length as short as possible.
 Clamp or braze the ground wire to the ground bed conductor
(typically a stranded copper AWG 0000 cable installed vertically or
horizontally).
 Tin the wire ends with solder (using a high-wattage soldering iron)
prior to inserting the wire into the housing ground lug.
 Run the ground wire so that any routing bend in the cable has a
minimum radius of 12-inches below ground and 8-inches above
ground.

Before we actually install the PSSM it in the housing, we’re going to
discuss some general information about how it works.
