6 Installation
6.1 Preliminary Inspection
Prior to removing the system from the crate, note any damage to the carton. Remove the system from the
packaging and inspect the shelf and components for any dents or damage. If any damage is noted, contact
the carrier immediately.
6.2 System Mounting
The power system is typically shipped with the shelf in one carton and rectifiers in individual cartons. The
shelf typically is shipped with the ALU and the distribution module. The module can be mounted in a
19”relay rack provided by the customer.
This system allows the relay rack to be installed as close to a rear wall as is necessary for the installation.
The front of the system should be clear of all obstruction and allow room for proper ventilation, installation,
and maintenance.
6.3 Module Installation
In order to reduce the weight of the system, all power modules can be removed from the shelf when mounting
the shelf onto a rack.
1) Ensure that the AC power is isolation.
2) Loosen the fixed thumbscrew on the rectifier and pull the rectifier out.
3) Loosen the fixed thumbscrew on the ALU panel and pull the ALU out.
4) Reverse the procedure, to install the rectifier and ALU.
6.4 Shelf Wiring
The shelf comes fully assembled and is equipped with the ALU and the distribution module. All internal
connections are made at the factory. No internal, shelf, or module wiring is required.
6.5 AC Input Connections
The power system is equipped with one power terminal located at the center rear of the shelf.
Warning: 1. AC power wire cannot less than AWG 10 and failure to use the appropriate power wire
causes safety hazards.
2. Each shelf requires a properly grounded AC input feeds supplied by Delta.
3. The system operates at AC voltages that can produce fatal electrical shock. Installation
and maintenance personnel must observe all safety precautions.
4. Confirm the operating voltage and proper grounding of the incoming line before
proceeding.
6.6 Battery String Connections (System equipped with PDU)
Warning: 1. Verify the polarity of the battery leads prior to connecting the battery cables to the system.
Failure to connect the battery cables correctly to the system can cause damage to batteries
and the system.
