2 –NESPACE Shelf- Typical Installation & Cabling
Example of NESPACE48/3K Rectifier Modules installed into a CSPS-6K Shelf
Figure 2-1. Shelf with NESPACE rectifier modules installed
2.1 Preparation for Rack Installation
The rectifier modules should be installed into a shelf using an indoor cabinet/rack in a clean, dry
location, with at least 50cm spacing front and rear of the shelf to allow for unrestricted air flow.
2.2 Cabling to a shelf containing NESPACE48/3K Modules
●Focus on and follow safety procedures while installing rectifiers.
●Before cable installation, use a DVM to verify AC and DC voltages
are not present. Use tagout/lockout, as needed.
●Before starting any operation, carefully read the following directions.
Inputs and outputs of the NESPACE rectifier is typically connected through a shelf backplane,
PCB traces, filter networks, bus bars, terminals, connectors, and cables.
Pay attention to AC input Line/Load/GND and DC output connection polarities.
2.2.1 AC Input Connection
The AC input includes a lightning surge arrestor (10kA) within the backplane in a typical shelf.
AC input cables to the Rectifier Shelf should be physically separated from DC output cables as
much as possible to minimize EMI.
The AC 1ø3W input cable may be connected after AC voltage is verified to be OFF and
LOCKED-OUT. A typical 1U Rectifier Shelf configured with NESPACE48/3K rectifier modules is
shown in Figure 2.2, which shows the the Shelf’s rear-side power cable connections.

4.4 Rectifier System Operation
①Check that each RM ON LED is illuminated (GREEN) for normal operation.
If the RM FAIL LED is on (RED), check module error status then remove
and reinsert the RM to check the status again.
②Verify that the RM ON LED is illuminated (GREEN) for normal operation.
If the FAIL LED is still on (RED), check the alarm displayed on the Control Unit LCD.
If any error on the rectifier system is not solved under the direction of above Table 3-1,
contact a Sales Representative or the headquarters of Dongah Elecomm.
4.5 Rectifier Removal / Replacement
①The Rectifier Modules are hot-swappable so can be replaced with AC power applied.
(Note that if any external battery has been connected, the Control Unit still operates.)
② The Control Unit is not hot-swappable so replacement requires that the AC input
voltage be turned off and all external batteries be disconnected (BATT circuit
breakers OFF). Then the Control Unit can be replaced and the system power
restored.
4.6 Rectifier Module Restart
If a Rectifier Module output voltage is suspended due to a DC OverVoltage (OV),
manually turn off the main AC Circuit Breaker. Then, when the module is fully
discharged (LED off), turn on the AC Circuit Breaker to see if the event was isolated
or recurring. If the OV condition is not recovered, replace the Rectifier Module and
repeat this restart process to check that the replacement module clears the alarm.

5 - Rectifier Maintenance
5.1 Overview
The purpose of this document is to provide guidelines to test the rectifier and setup
measures to restore the rectifier to normal operation within a shortest possible time
when any fault occurs to the system. Enough field-replaceable spare parts must be
maintained on-hand to prepare for replacement of units or components that may fail in
the field. Even though the fault location and reason are detected under the guidelines of
this Manual, if field repair work is not possible, or a long period of time is needed for
repair, the faulty units should be replaced with a spare one held in reserve. This allows
the system alarm to be cleared quickly and efficiently to minimize technician time and
maximize system up-time.
Note: As this rectifier is powered by AC voltage, it naturally may cause electric shock. If
external battery banks are also used, this battery voltage is fed to the system even
during an AC failure event. Because of the AC and/or DC presence, safety measures
should be taken during rectifier shelf repair and maintainance.
5.2 Periodic Inspection of Rectifier Shelf, Modules, and System
To guarantee effective operation of the system, periodic inspection is required.
Periodic inspection should be carried out once every 6 months.
1) Take care not to block the air ventilation holes with dust, dirt, or other debris.
2) Check the cable connections and tighten as necessary.
3) Check if internal temperature of the site is maintained at the rated levels.
4) Visually check all rectifier operation states and alarm states.
5) Check the equipment rack floor mount is maintained and ensure there is not any
water leakage at or near the installation site for the rectifier system.
5.3 Adding Rectifier Module
To expand the system capacity, rectifier modules are hot-swappable so may be inserted
into vacant slots while the Rectifier Shelf is powered up normally.

NESPACE48/3K Operation Manual
Issue 1.0 March-2017
KE NESPACE KA Rectifier Control Unit Operation Manual English R 2016_07 V1_1 19 /21
1) Insert a rectifier module to the vacant slot until it reaches the mating connector then
push in the ejector to fully seat the connectors. The ejector will easily lock into place
when inserted and seated.
2) Confirm the Rectifier Module ON LED is illuminated GREEN.
3) On the Control Unit, check operation status of the newly inserted module for no
active alarms.
6–Problem Solving & Fault Fixing
Repairing or troubleshooting Rectifier Shelves and Rectifier Modules should only
be performed by experienced workers observing all safety precautions.
* Jobs should be carried out in due order.
* Workers should not wear rings, watches or metallic accessories.
* If non-insulated conductors are used, always use a DVM toverify if any voltage is
present before attempting to perform any work in or around the Shelf or Rectifier.
- Circuits and boards should be protected from EMI.
6.1 Problem Solving
This rectifier has been designed for users to solve problems easily. The Control Unit LCD
window displays details of faults.
6.2 Replacing Parts within a Shelf
If a fault is suspected on a particular point, the field-replaceable unit (circuit board or
module) at that point should be replaced. Replacing individual components on a circuit
board or module should not be performed in the field.
6.3 Order of Replacement
6.3.1 Replacement of Rectifier Module
1) When a rectifier module is replaced, an alarm will be activated. Turn off the rectifier
module alarm from the control panel, or notify this fact to the person in charge.
2) To remove the faulty rectifier module, push in on the ejector on the Rectifier Module,
and then pull the ejector handle to remove the module from the shelf.
3) Slide in a new Rectifier Module along the mechanical guides until it reaches the

backplane connector.
4) Carefully push in the ejector handle to lock the mating connectors. The ejector
handle should easily snap into place and lock into the Rectifier Module front panel.
5) Check that the module operates normally and that no alarms are activated.
