3: System Installation
3.1 General
NOTE: ABB POWER recommends that the Maintenance Bypass Panel is installed above the top-most
827E Inverter Shelf (refer to Figure 3-1). ABB POWER recommends leaving one rack mounting space
between the MBS and the first Inverter shelf as well as from Inverter shelf to inverter shelf to allow air
flow between units for proper heat dissipation (refer to Figure 3-1).
CABLING:
A. Remove the maintenance bypass panel from the shipping container.
B. Install the panel as follows:
1. Ensure there is proper clearance in the rack to install the maintenance bypass panel.
2. Put the panel into position and secure with the screws located at each outside corner (four screws total).
NOTE: The maintenance bypass panel is designed to be either flush or mid mounted.
