• Before installing an AC input power cable, ensure that the upstream AC input switch is turned
off and a prominent label indicating "Do not operate" is set.
• AC switches (with a capacity of 40 A) must be installed for phases L and N of the iSitePower-
M AC input. The AC switches are delivered with the iSitePower-M. Do not use a Type D circuit
breaker because it cannot effectively protect products.
