Optima 529 Series
1.5 General Description
The Optima 529 Series (model numbers MPD 529XXX) is a family of 16 power distribution units (PDUs) designed for use
with a single-phase supply power of either 120 Vac, 110–240 Vac, or 200–240 Vac.
Each PDU receives mains power through an inlet located at the bottom. Power is distributed to all outlets on one, two, or
three branches depending on the model. A variety of inlet and outlet connectors is available.
All models include a circuit breaker with indicator. All models are constructed of a steel chassis, are designed for xed
mounting within a 0U rack space in an EIA-310 compliant rack enclosure, and include tool-less buttons and congurable
mounting brackets for exibility in mounting.
1.6 Product Models
Models are primarily organized by size (full height and half height), then by the outlet congurations. Marway’s Standard
Products Catalog includes more detailed tables with exact model number congurations with inlets, outlets, and options
identied.

2 Installation
2.1 Installation Notes
The following guidance must be followed for proper
installation of the product.
1. Mounting: This product is designed for mounting
in an EIA-310 compliant 19” rack. The user is
responsible for ensuring the mounting method
provides adequate structural support for the
product, and any attached cables. The user
is also responsible for ensuring the mounting
location provides adequate ventilation to
dissipate heat generated during operation of the
product. Ensure the product is securely mounted
before applying power.
2. There are multiple mounting congurations
derived from the relocatable positioning of the
optional mounting plates, or the use of tool-less
mounting buttons without plates (concentric
circles shown in red). Model-specic details are
available from the web site Product Selector.
3. Chassis ground: The rear of the chassis includes
a redundant chassis ground screw and ground
wire. If desired for your installation location,
connect the chassis ground wire to the rack
cabinet using an appropriate fastener.
4. Optionally, connect the appropriate cables between the PDU outlets and the equipment being powered by the PDU.
This may be done later according to the startup procedures suitable to the end-user’s equipment and application.
5. If applicable, connect the cabling between the PDU and remote EPO control panel.
6. PDU Main Breaker: Ensure the Main Breaker on the front of the PDU is in the off position before connecting the
PDU’s inlet cable to the facility power source. (It is best to switch all breakers to the off position.)
7. Facility Power Source: The single-phase facility power source for this product must include an overcurrent protective
device capacity as dened in the table below.

3 Operation
3.1 Startup
Switch the breaker(s) on the PDU chassis to the off position.
Insert the PDU’s inlet connector into the facility mains power source. If there is a facility power disconnect, switch that to
the On position. At this point, the PDU is energized, though the indicator lamps will be off.
Switch the PDU’s breaker(s) to the On position, and the indicator(s) will be lit. All outlets are now powered.
3.2 Breakers
Various models have one breaker or three breakers.
When there is a single breaker, in effect this behaves like a main breaker, protecting the whole unit, and providing on/off
control for the whole unit.
When there are three breakers, each breaker protects one group of outlets. Outlets are organized into identical groups.
Following the length of the PDU from the inlet, the rst breaker operates the rst group of outlets, etc.
Each breaker has it’s own indicator. When lit, power is being supplied to the correlating outlet group.
All models use 2-pole breakers with both line and neutral routed through the breaker.

Inlet Voltage Options
• 120 Vac, 50/60 Hz, single phase
• 100–240 Vac, 50/60 Hz, single phase
• 200–240 Vac, 50/60 Hz, single phase
• All voltages are listed as nominal input sources.
Current Capacity Options
• 12 A continuous load / 15 A maximum
• 16 A continuous load / 20 A maximum
• 24 A continuous load / 30 A maximum
• Based on NEC regulations, traditional load ratings are de-rated to
80% for continuous duty. For example, a traditional 30 A maximum
rating is now interpreted and labeled as a 24 A continuous duty
rating. Optima current ratings are shown with continuous/maxi-
mum rating values.
Overload Protection (standard)
• All models include UL 489 two-pole circuit breakers.
• All single-phase models are wired with both line and neutral
passing through the two-pole circuit breaker.
• All multi-breaker models are wired with one outlet group per
breaker.
Environment
• Operating Temperature: 32°F to 122°F
• Maximum Altitude: 6,562 feet
