NOTES:
1. The 538S units contain a 24-v transformer; additional transformers
are not required.
2. All motors and compressors contain internal overload protection.
3. In compliance with NEC requirements for multimotor and combina-
tion load equipment (refer to NEC Articles 430 and 440), the over-
current protective device for the unit shall be fuse or HACR breaker.
4. Motor RLA values are established in accordance with UL (Underwrit-
ers’ Laboratories) Standard 1995.
