For those that saw my issue regarding my AUX powered ELK-WSV noticed my solution was to connect the OPII Ground to Altronix Ground. This lead me to another question to make sure I have my earth grounds and DC grounds all correct.
Here is my equipment:
OmniProII (OPII)
Expansion Enclosure #1 (EE1)
Expansion Enclosure #2 (EE2)
Altronix OLS180 Power Supply (OLS 180)
Altronix PD16W Power Distribution (PD16W)
Here is how I am understanding the ground related connections for each and attempt to delineate between EARTH GROUND AND DC (-).
Assumptions:
1. My OPII, EE1 and EE2 are all powered via 120VAC ELK Transformer with 2 AC connection and Ground Connections.
2. My home wiring is new with ground wire at all receptacles. Home was built in 2012.
3. Both Leviton 42" metal Cans are earth grounded to a grounding block connected to my electrical panel's ground.
EARTH GROUND Connections to be made:
OPII "EARTH GND" Terminal ---> ELK Transformer #1 GND Terminal (from grounded receptacle)
EE1 "EARTH GND" Terminal ---> ELK Transformer #1 GND Terminal (from grounded receptacle)
EE2 "EARTH GND" Terminal ---> ELK Transformer #1 GND Terminal (from grounded receptacle)
Altronix OLS180 "G" Terminal ---> Plug ground (from grounded receptacle)
DC (-) Connection to be made:
OPII GND Terminal ---> EE1 GND Terminal ***(I understand this can be any of DC GND Terminals, for example Switch GND or AUX GND???)
EE1 GND Terminal ---> EE2 GND Terminal ***(I understand this can be any of DC GND Terminals, for example Switch GND or AUX GND???)
EE2 GND Terminal ---> Altronix PD16W "N" Terminal by "XFMR Input"
Questions:
1. Do Cans need connected directly to earth ground or the fact that all tie to same grounding block at breaker panel sufficient?
2. I DO NOT cross connect the EARTH GROUNDS to any DC Ground, correct?
3. To link DC GNDs for OPII, EE1, EE2 the switch GND, AUX GND and for that matter all other GNDs on the board are all tied together on the PCB correct?
