Notes:
1 . All wiring to be in accordance with National Electrical Code and any local codes.
2 . Auxiliary equipment must be powered from other sources as the chiller control panel power supplies are sized for the chiller loads only.
(a) Ground lug for a unit-m ounted solid state starter or wye-delta starter is sized to accept 14 AWG solid to 8 AWG strand wire. For AWG/ MCM equivalents

, refer to
Table 12, p. 47. If local codes require different lug size, it must be field-supplied and -installed.
(b) Refer to submittal and ship-with wiring schem atics for voltage requirements.
(c) Must be separated from 120 Vac and higher wiring.
