Ensure that wiring conforms to all applicable local and national electrical codes and install
unit(s) according to relevant national and local safety codes.
Electrical power must be disconnected from explosion proof models before
the cover is removed. Failure to do so could result in severe personal injury
or substatnial property damage.
1. Remove housing cover.
2. Observe applicable electrical codes and recognized wiring practices.
3. Remove two mounting screws and slide out PC board to expose green
ground screw (Internal Primary Equipment Ground/Earth) in base of housing.
4. Connect green line ground wire to green ground screw on base of housing.
(Ground wire should be a minimum of 18-AWG.)
5. Reposition PC board, replace and tighten mounting screws. Ensure that
banana plug on sensor lead wire is secure in sensor jack.
6. Connect hot line power wire (typically black) to L1 position on the terminal block.
7. Connect neutral line power wire (typically white) to N position on the
terminal
block.
8. Replace cover.
9. Apply power as desired.
1. Perform Steps 1 through 6 above.
2. Connect second hot line power wire (typically red) to L2 position on the
terminal
block.
3. Replace cover.
4. Apply power as desired.
1. Perform Steps 1 through 5 above if a case or equipment ground wire is
provided for connection to earth ground.
2. Connect positive line power wire to the terminal marked (+).
3. Connect negative line power wire to the terminal marked (–).
4. Replace cover.
5. Apply power as desired.
