MASTERseries Quick Start Guide
2-Slot Chassis Installation
If You are Using Redundant Power
Supplies...
Power must be connected to both A and B
feeds. Attach the leads to the appropriate
terminals as indicated in the diagram at the
right.
If You are Using a Single Power
Feed with Dual Power Supplies...
If you only power the A feed and are using
two power supplies, you need to jumper
between Input A and Input B and also
between Return A and Return B. Make this
jumper the same gauge as the feed. Attach the
leads to the appropriate terminals as
indicated in the diagram at the right.
Ferrite Bead
A ferrite bead is required on the power cable. Install a ferrite bead (part number 010-0051) on the
power cable with a loop as shown below. It is recommended that the ground wire be included in the
ferrite bead.
