Optima 320 Series
1.5 General Description
The Optima 320 Series (model numbers MPD 320XXX) is a family of 11 power distribution units (PDUs) designed for use
with a single-phase supply power of either 120 Vac or 100–240 Vac.
Each PDU receives mains power through an inlet located at the rear of the 1U chassis. Power is distributed to all outlets
on one or two branches depending on the model. A variety of inlet and outlet connectors is available.
All models except the 320001 include surge suppression, an EMI lter, an indicator for each circuit breaker, and an
external chassis ground lug. For models with cords, a 10 foot cord is included. All models are UL and CE certied.
All models are constructed of a steel chassis, are designed for xed mounting within a 1U rack space in an EIA-310
compliant rack enclosure, and include removable/reversible mounting brackets.

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. 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.
3. 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.
4. 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.)
5. 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.

2.2 Installation Mounting
EN — These products are heavy. The ange mounting ears are designed to hold the PDU securely
against the rack mounting rails, but are NOT designed to support the weight of the product
vertically. The end user is responsible for ensuring the product’s weight is properly supported by the
rack’s infrastructure (which may require adding support rails).
FR — Ces produits sont lourds. Les oreilles de montage à bride sont conçues pour maintenir
solidement l’unité de distribution de l’alimentation contre les rails de montage, mais NE sont
pas conçues pour soutenir le poids du produit verticalement. Il incombe à l’utilisateur nal de
s’assurer que le poids du produit est correctement supporté par l’infrastructure du bâti (ce qui peut
nécessiter l’ajout de rails de support).
(A) The mounting ears, highlighted in blue, can be positioned ush with the front, or recessed from the front. They can also
be ipped (not shown) to mount the rear panel ush or recessed from the rear of the PDU.
(B) The PDU should be supported by rails (not provided). The PDU is too heavy to mount only with the ears.

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 two circuit breakers. The 320001 does not have a circuit breaker.
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 two breakers, each breaker protects one group of outlets. Outlets are organized into identical groups. The
breaker on the front panel protects the outlets on the front panel, and the breaker on the back panel protects the outlets
on the back panel. (The back panel is the one with the inlet connection.)
Each breaker has it’s own indicator. When lit, power is being supplied to the correlating outlet group.
3.3 Digital Meter
Some models include the monitoring and digital display of volts and amps. The meter will auto rotate every 5 seconds
between the volts and amps values. Volts are shown as whole numbers. Amps are shown with one decimal place. Both
values are ≤ ± 2%, and are recalculated every 15 seconds.

4 Specications
Inlet Voltage Options
• 120 Vac, 50/60 Hz, single phase
