RT9 Powershelf Rectifier Technologies 1. General Warnings 1. This equipment has been designed to be used only in restricted access areas. 2. This equipment must only be serviced by authorised and qualified service personnel. 3. Operators should not attempt to repair faulty units. There are no operator serviceable parts inside.
Rectifier Technologies 2. Configuration 2.1 General Description RT9 Powershelf systems are turn-key DC uninterruptible power supply solutions (DC UPS) for powering 24VDC or 48VDC telecommunications and industrial equipment. Powershelf provides integrated battery management functions for a range of battery types (VRLA, flooded Lead-acid, NiCd, Ni-MH, Li-polymer) to enable easy commissioning of a DC UPS or it can be used as a standalone DC source when no batteries are used.
RT9 Powershelf Rectifier Technologies 3. Installation 3.1 Mounting the Powershelf The Powershelf is mounted into a standard 19” rack using M5 or M6 screws and cage nuts. For systems larger than 4U (rack units) in height, multiple standard Powershelf magazines are strapped together by four of 18x63mm strapping plates – two at the rear that must remain in place, and two on the front that can be removed once the shelf is secured in the rack.
RT9 Powershelf Rectifier Technologies 3.1.2 Gaining Access to Rear Wiring NOTE: Access to the rear wiring should be limited to qualified service personnel. It is recommended to remove the AC power before gaining access to the rear wiring due to the safety hazard present inside the electrical enclosure.
RT9 Powershelf Rectifier Technologies The switched battery cables (-ve in a –48V system) terminate on the copper bars of the battery distribution module (item 2 in Figure 2.3), while the battery return cables terminate on the common return bar (item 3 in Figure 2.3). The battery distribution module can be configured for up to four battery strings with the appropriate number of return cable termination points being available on the common bar.
RT9 Powershelf Rectifier Technologies 3.3.1 Factory Supplied Configurations Powershelves without internal AC distribution (eg. PSLF-1115), unless specially ordered, are configured with each rectifier active line being terminated in an individual DIN rail terminal block (beige) and the remaining AC line is connected to a common neutral bar (blue terminal blocks).
RT9 Powershelf Rectifier Technologies 3.3.3 3 phase star – individual protected external feeds Remove the link connecting the active terminals “A” together. Connect one phase wire per “A” terminal. Connect the neutral wires to the common neutral terminals. Figure 3.6 3.3.4 3 phase delta –...
RT9 Powershelf Rectifier Technologies 3.3.5 Surge protection requirements The rectifiers are internally protected for surges up to 6kV/3kA. For higher levels of protection, particularly for sites with high incidence of lightning or switching surges, additional surge protection is required on the AC feed to the Powershelf. Typically surge...
RT9 Powershelf Rectifier Technologies 3.4 Bulk Load connections Figure 3.9 A bulk load can either be a single large load, or a cable connection to an additional, external DC distribution unit. There are two M6 studs available for securing either 2 cables with single-hole lugs or a cable with double-hole lugs.
RT9 Powershelf Rectifier Technologies Figure 3.10 3.6 Battery connections Figure 3.11 For –48VDC systems, the battery negative cables are terminated on the switched line terminals of the battery distribution module (shown above), while the battery positive cables are all tied to the common return bar. The cables can be either brought out through the cut out adjacent to the return bar, or through the break-out slot in the top cover.
RT9 Powershelf Rectifier Technologies 3.7 Temperature Sensors The optional sensors for measuring ambient and battery temperature are the same device (Part No. 804-1100-01). The system auto-detects if the sensor is plugged into one of the positions (4) or (5) shown in Figure 2.4. If no sensor is installed, the MiniCSU-3 will show “Not Available”...
RT9 Powershelf Rectifier Technologies 3.9 MiniCSU-3 Power Connections Power for the MiniCSU-3 and its peripherals is derived from the DC bus or the highest charged battery. The Battery distribution module has reverse polarity protection circuit that also serves to provide an “or-ing” of the highest supply voltage for the MiniCSU-3. There is one common connection to the +VE bus (in the case of a –48V system) and one...
RT9 Powershelf Rectifier Technologies The following sections describe the interfaces in more detail and cover some of the set up requirements for the more advanced interfaces. 3.11.1 Isolated RS232 Interface This interface should be used if the distance between the Powershelf and a monitoring PC is not greater than 15 meters.
RT9 Powershelf Rectifier Technologies For connection to a PC a suitable interface should be used (ie. Plastic Fibre Modem SY – 1025101 manufactured by Foxbro Company, a division of Invensys). Optical cable/connectors are not provided. It can be ordered from your local Hewlett Packard distributor (ask for Versatile Link Fiber Optic accessories data sheet).

RT9 Powershelf Rectifier Technologies Note: the above connection information is relevant when the LVDS is a battery disconnect. If the LVDS is a load disconnect, the DC bus side wiring of the circuit breakers is reversed such that the battery connections come off the DC bus side of the LVDS, while the load is taken off the LVDS common busbar.
RT9 Powershelf Rectifier Technologies 4. Commissioning With all the batteries, load and AC cabling wired, and checked for correct polarity, the system is commissioned by the following steps: • Ensure no rectifiers are installed in the Powershelf and no load is applied.
RT9 Powershelf Rectifier Technologies 5. Operation System operation is controlled by the MiniCSU-3 system controller. As a result, operation information for the system is directly related to the operation of the MiniCSU-3 as described in this section.

RT9 Powershelf Rectifier Technologies 5.1 MiniCSU-3 Components 5.1.1 Alpha-numeric Display The user interface is a two-line by 16 character alphanumeric OLED display. The 5mm high characters normally display output voltage and current as well as the system status - Float (FL) or Equalise (EQ). This is the default or “home” screen.
RT9 Powershelf Rectifier Technologies 5.2 MiniCSU-3 Security & Alarms 5.2.1 Password security MiniCSU-3 features password security for setting of parameter. A valid password is an alphanumerical code having minimum three and maximum eight characters. Units leave the factory without a pre-programmed password and the security function is not active.
