Helios Rectifier 25/48 Installation and User Manual

Installing the AC power

Permanent AC connection to the MPS75 power shelf is done using two

armored cable conductors, RW-90 or equivalent, as listed in Table 2. One

must be routed to L1, and the other one to L2 and to the safety shelf frame

ground (FR GND). The cabling must comply to the local electrical code. The

power shelf is equipped with a strain relief to terminate the conduit. The

cable length should be minimized and be properly secured.
