The recommendations in this table are guidelines only and are superseded by local regulations and codes of practice where applicable:
1.Recommended cable sizes are 75C (THW) wire at 86°F (30°C) ambient.
2.For continuous operations not at 86°F (30°C), Emerson recommends selecting the appropriate cable type based on the particular installation requirements.
3.The ground conductor should be sized according to the fault rating, cable lengths, type of protection, etc. The ground cable connecting the UPS to the main ground system must follow the most direct route possible.
4.When laying the power cables, do not form coils. Coiling power cables increases the likelihood of electromagnetic interference.
