    6. Facility Power Source: The three-phase facility power source for this product must include an overcurrent protective device with a maximum rating of 30 Amps. The Optima 533 is a heavy product. The flange mounting ears are designed to hold the PDU  securely against the rack mounting rails, but are NOT designed to support the weight of the PDU  vertically. The end user is responsible for ensuring the PDU’s weight is properly supported by the  rack’s infrastructure (which may involve adding support rails).

    C indicators will be lit. All branch circuits are ready for use. As each branch breaker is switched on (e.g. CB1 ,  CB2 , etc.), the indicator above it will be lit. If there is not an EPO panel connected to the PDU, leave the switch in the up  Local/On position. If there is remote EPO panel connected to the PDU, such as Marway’s Commander UCP 5000, flip the  Outlet Control Bus switch to the down Remote position. 3.2 Breaker Controls The PDU has three distinct groups of controls: the main breaker, the branch breakers, and the remote EPO system.

    There is a small pop-out breaker protecting the control system components. This isn’t used during normal operation. If it were to pop out, try pressing it back in. If it fails to stay in, there may be  failure in one of the controls which is shorted, or  is drawing excessive current. This would likely indicate the need for an RMA repair. Contact Marway support. 3.3 EPO Controls All Optima 533 PDUs include the controls to interface to Marway’s Commander UCP 5000 Remote On/Off/EPO panels ...
  • Page 9: Remote Bus Connectors

    Remote Bus connectors have two different numbering systems depending on the model. (Why? A convention from the military equipment realm is that all connectors are labeled sequentially. Since some models have 8 outlet junctions, and  some have 9 outlet junctions, the subsequent connectors for the Remote Bus have labels of either J9, J10, J11, J12, or  J10, J11, J12, J13.) Models with J1 through J8 Outlets The standard enable connectors are J9, J10, J11. These are all wired in parallel. The delay connector is J12. When used, the On signal from the remote panel is delayed by about 2 seconds. Models with J1 through J9 Outlets The standard enable connectors are J10, J11, J12. These are all wired in parallel. The delay connector is J13. When used, the On signal from the remote panel is delayed by about 2 seconds. Page 9 Optima 533 Series...
