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). Page 6 Optima 820 Series... -
Page 7: Operation
2. If the unit is equipped with the UCP Control Mode switch, whether there is a remote EPO panel connected to the unit or not, toggle the switch to the up position labeled EPO Only . (The label has changed over the years, but the up position always functions the same way.) 2.1 This switch position is required if there is no EPO panel. 2.2 If there is a remote panel, this puts the PDU into a local control mode, ignoring the remote On/Off controls, but allowing the EPO signal.) 3. If there is a facility disconnect switch for the PDU inlet, switch that off. 4. 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. 4.1 At this point, the PDU control system is energized. Outlets will not have power, because the PDU’s Main Power breaker is off, but the software will begin its startup process. The default factory setting configures the software to switch the outlet relays on, however, while the main breaker is off, power is not actually delivered to the outlets. Allow about a minute for the software to switch on the relays. 5. Switch the PDU’s Main Power breaker to the On position, and the indicator will be lit. This indicator does not necessarily mean power is applied to the outlets. It simply means the main breaker is on and power is available to Page 7 Optima 820 Series... -

Telnet, SSH, HTTP, SNMP, and RESTful API. The Ethernet connection supports 10/100 Base-T, IPv4 DHCP and manual addressing. It is recommended to use a manual address, or DHCP in conjunction with MAC ID reservations so that the IP address stays consistent. The Serial interface is RS-232 implemented in an RJ45 connector. A protocol conversion cable with a USB connection at one end and an RJ45 at the other end is ideal for connecting a computer to the Serial port. Marway offers these cables as part number 311118-000. They can also be found on many online cable retailer web sites. Breaker Controls 3.3.1 Main Breaker The Main Breaker enables/disables power to all PDU outlets. When Main Breaker is switched on, the Main Power indicator labeled will be lit. If the PDU is equipped with the UCP Control Mode mode switch, the Off position will disconnect power from the outlets even if the main breaker is on. 3.3.2 Branches All models use a 2-pole main breaker. However, that breaker is used a couple of different ways across the product line. The following descriptions should help to explain the ratings table above. 12/15 A Rated Units (Group 1) All models with a 12/15 A inlet rating have both line and neutral connected to the breaker. All outlets are on a single branch. Therefore, the total continuous load for the whole PDU is 12 Amps. With 5-15R outlets, any one outlet can carry Page 8 Optima 820 Series... - Page 9 UCP Control Mode Optima RCM Ethernet Serial Aux 1 Aux 2 Values Branch 1 J 10 Enable Disable Return Branch 2 For Group 6 units with 5-15R outlets, each breaker branch is rated for 12/15 A. Any one outlet can carry a continuous load up to 12 Amps (with no draw on other outlets), or a combination of outlets on one branch can draw a total of up to 12 Amps. The total for the whole PDU is 24 amps (the rating of the inlet connector, which happens to coincide withe the sum of the branches). For Group 7 units with 5-20R outlets, each breaker branch is rated for 16/20 A. Any one outlet can carry a continuous load up to 16 Amps (with no draw on other outlets), or a combination of outlets on one branch can draw a total of up to 16 Amps. The total for the whole PDU is 24 amps (not 32!) which is the rating limit of the inlet connector. For Group 8 units with C13 outlets, each breaker branch is rated for 12/15 A. Any one outlet can carry a continuous load up to 10 Amps (with no draw on other outlets), or a combination of outlets on one branch can draw a total of up to 12 Amps. The total for the whole PDU is 24 amps (the rating of the inlet connector, which happens to coincide withe the sum of the branches). Page 9 Optima 820 Series...

Page 10: Controls Breaker
• Normal (down position) is the normal operating mode. Outlets 1–8 are subject to the remote panel On/Off/EPO controls (and, of course, the internal software-controlled relays). • Outlets Off (center position) causes an internal contactor to disengage power from outlets 1–8. Outlet 9 is not affected. The PDU will ignore the On/Off/EPO commands of the remote panel. Therefore, Off disconnects power to outlets 1–8 even if the main breaker is switched on, and even if the internal software-controlled relays are switched • EPO Only (up position) causes the PDU to ignore the On/Off commands of the remote panel. The EPO signal is still allowed. When there is not a remote control panel connected: • EPO Only (up position) is the normal operating mode. Effectively, this is a Local Control mode. • Outlets Off (center position) causes an internal contactor to disengage power from outlets 1–8. Outlet 9 is not affected. The PDU will ignore the On/Off/EPO commands of the remote panel. Therefore, Off disconnects power to outlets 1–8 even if the main breaker is switched on, and even if the internal software-controlled relays are switched • Normal (down position) will behave like Off. (With no remote control panel connected, this label is a bit of a misnomer as this would not be the normal position.) Page 10 Optima 820 Series... -

Breaker UCP Control Mode Optima RCM Ethernet Serial Aux 1 Aux 2 Values The display will default to showing the amperage being drawn by the system as a whole (all 9 outlets, plus the internal control system). It will update approximately every 3 seconds. The keypad can be used to navigate through power values for volts, amps, watts, voltamps, voltamps reactive, power factor, and Hertz. For complete display and keypad details, refer to the document Optima RCM User Guide : Software and Basic Controls Reference located on our website at http://www.marway.com/docs. Obtain that document, and review the Display and Keypad Operation chapter. EMI Filter Option There are no control associated with the EMI filter. It is a passive device working at all times to reduce common mode and differential mode noise on the incoming power lines. Page 12 Optima 820 Series... -

Circuit breaker for internal control circuitry. (7) Ethernet, RS-232 serial console, and auxilary connections. All are RJ-45. Auxilary connectors are for Marway Temperature/Humidity sensors. Mounting brackets. May be mounted in one of three locations to yield a “flush,” recessed, or rear- facing position of the chassis relative to the rack’s mounting flanges. May also be removed for table top operation, or adaptation of end user’s own custom brackets.

Questions and answers
what are the key functional differences between the 820105-psw-001 and 820105-psw-000
The key functional difference between the Marway Optima 820105-psw-001 and 820105-psw-000 is the type of remote Emergency Power Off (EPO) circuit:
- 820105-psw-000 has a Normally Open (N.O.) EPO type.
- 820105-psw-001 has a Normally Closed (N.C.) EPO type.
Both models have inlet power monitoring and outlet switching capabilities (PSW).
