Field Power Supply
Field Control Wiring
NOTES:
1. Factory wiring is in accordance with UL 1995 standards. Field
modifications or additions must be in compliance with all appli-
cable codes.
2. All units or modules have single point primary power connec-
tion. Main power must be supplied from a field or factory-sup-
plied disconnect.

3. Wiring for main field supply must be rated 75 C. Use copper
conductors only.
4. Incoming wire size range for terminal block with MCA (minimum
circuit amps) up to 175 amps is 14 AWG (American Wire Gage)
to 2/0.
5. Incoming wire size range for terminal block with MCA from
175.1 amps to 420 amps is 2 AWG to 600 kcmil.
6. Incoming wire size range for non-fused disconnect with MCA
up to 100 amps is 14 AWG to 1/0.
7. Incoming wire size range for non-fused disconnect with MCA
from 100.1 amps to 200 amps is 6 AWG to 350 kcmil.
8. Incoming wire size range for non-fused disconnect with MCA
from 200.1 amps to 450 amps is 3/0 to 500 kcmil.
9. Terminals 1 and 2 of the LVT are for the alarm relay. The maxi-
mum load allowed for the alarm relay is 5 va sealed and 10 va
inrush at 24 v. Field power supply is not required.
10. Refer to certified dimensional drawings for exact locations of
the main power and control power entrance locations.
11. Terminals 24, 25, and 2 of the LVT are for control of the field-
supplied LLSV. The maximum load allowed for each LLSV is
40 va at 24 v. Field power supply is not required.
12. All discrete inputs are 24 vac.
13. LLSV (24-v) should be 40 va maximum per valve as required.
14. Installation of fan status switch (FS1) is recommended.
15. The contacts for remote ON/OFF, fan status, and demand limit
options must be rated for dry circuit application capable of han-
dling a 24-vac load up to 50 mA.
