3.4.a Electrical Requirements
WARNING - Failure to heed the following may result in injury or death.
The information contained in this section is intended for use by qualified electricians familiar with electrical
l
service-industry safety standards and methods.
Locate the equipment disconnect as near to the chiller as possible. Always satisfy applicable codes and
l
standards.
Never mount power-disconnects directly to the chiller.
l
In sizing power wiring, be especially aware of up-sizing requirements necessary due to wiring distances. Always
l
satisfy applicable codes and standards.
Multiple chillers installed at the same site may benefit from automatic sequencing controllers (ASC) to avoid
l
excessive power drops at start-up. See "Available Accessories" on page 27.
