Installation Instructions

FOR 7500 SERIES MODELS ONLY
7. Make all wire connections by using appropriate UL-listed electrical
connectors and techniques.
8. Select the applicable wiring situation and follow the instructions accordingly:
•1-Phase 220-240 VAC
When connecting the Zoneline to a single-phase circuit for
230V applications:
Connect the white and black leads of the Zoneline power supply kit to the branch
circuit L1 and L2 leads. (The white lead of the power supply kit should be
identified by the installer using electrical tape with some color other than green or
white.) Connect the green lead of the power supply kit to the power supply and
branch circuit ground.
3-Phase 208 VAC
When connecting the Zoneline to a three-phase circuit for
208V applications:
Connect the white and black leads of the Zoneline power supply kit to the branch
circuit L1 and L2 leads. (The white lead of the power supply kit should be
identified by the installer using electrical tape with some color other than green or
white.) Connect the green lead of the power supply kit to the power supply and
branch circuit ground.
3-Phase 208 VAC with “Crazy Leg”
When connecting the Zoneline to a three-phase circuit with “Crazy
Leg” for 208V applications:
Connect the white and black leads of the Zoneline power supply kit to the branch
circuit Neutral and L1 leads. (The white lead of the power supply kit should be
connected to neutral.) Connect the green lead of the power supply kit to the
power supply and branch circuit ground.
9. Be sure that all wire leads are inside the junction box and not pinched
between the box and the unit. The green insulated ground wire from the
Zoneline MUST be connected to the branch circuit ground wire.
10. Plug the 9-pin connector into the 9-pin receptacle in the junction box.
11. Replace the junction box cover by replacing the two screws removed
earlier.
12. Replace the case front panel by replacing the four front screws and
the two top screws. Replace the filter.
