8. Per UL and the NEC an insulated grounding conductor, identical in size and
insulation characteristics to the supply conductors, is to be installed as part of
the branch circuit that supplies the unit or system. The grounding conductor
should be green, with or without yellow stripes.
9. The grounded conductor described up above is to be grounded to the earth at
the service equipment or if supplied by a separate derived system, at the
supply transformer or motor-generator set.
10. The AC receptacles in the vicinity of the power system are all to be of a
grounding type and the grounding conductors serving all receptacles are to be
connected to earth ground at the service equipment.
11. Caution - When changing rectifiers - Do not install or remove any rectifiers with
the power switch on. The power switch must be turned to the off position prior
to inserting a rectifier module from the shelf.
12. Before the system is operational, the AC input frequency and voltage must be
verified making sure the AC breaker rating and type are adequate and other
environmental conditions as noted in the specifications are met.
13. A readily accessible disconnect device shall be incorporated in the building
installation wiring.
14. Protective systems or devices in PRIMARY CIRCUITS shall be in such a
number and located so as to detect and to interrupt the overcurrent flowing in
any possible fault current path (for example, line-to-line, line-to-neutral, line to
protective earth conductor or line to PROTECTIVE BONDING CONDUCTOR).
15. In a supply using more than one line conductor to a load, if a protective device
interrupts the neutral conductor, it shall also interrupt all other supply
conductors. Single pole protective devices, therefore, shall not be used in such
cases.
16. Protective devices in three-phase equipment:
17. The system has passed stringent system testing prior to shipment. To avoid
electrical shock, the system requires a single ground point permanently
connected to earth ground.
18. Recommended room ambient is 50 degrees C.
19. To avoid electrical hazards, the covers must not be removed on the system or
any component including the rectifier and DC-DC converter.
Ericsson Series

20. DC output & battery breakers must be replaced with approved replacement
circuit breakers meeting the original design specification.
21. All AC connections must be made per the latest issue of the National Electrical
Code and must conform to all local codes.

3. Re-tight the battery tray
System Mounting
The shelf comes fully assembled with the DC Distribution Shelf, rectifiers mounted
in a 23” shelf. The AC connections from the AC terminal to the rectifier shelf are
made at the factory. All CSU communication and signal leads are connected via
the modular plugs and communicate with the rectifiers.
Mount the shelf with a distance no less than 4 inches from the rear of the rectifier
shelf to a wall. This will provide adequate ventilation for the rectifiers. The front of
the shelf should be clear of all obstruction and allow room for proper ventilation,
installation and maintenance. The shelf should be mounted to the superstructure
and floor per customer provided equipment engineering drawings.
3.5
Module Installation
In order to minimize the weight of system, all rectifier modules can be removed
from the shelf and re-installed.
3.5.1
Rectifier Installation
1) Install rectifier modules into the shelf
Warning! Do not force the module into the slot. If it does not slide in and connect
easily, remove and re-seat the unit.
2) Push both locker to lock position to lock the rectifier.
3.6
System Wiring
The shelf comes fully assembled and all the connections are made at the factory.
There is no internal, shelf or module wiring required.
All wiring to the breaker are use lead with striped ends. Ensure to tight the screw
and keep the wires are all into the breaker terminal, no any wires or threads are
remain outside of the breaker to avoid short-circuit. Refer to the figure below.

location is on the top of the rack (with a DC Ground mark). Refer to the figure
below for the correct grounding terminal location.
Recommended Wire: AWG # 4
Recommended Lug: Two-hole Lug (Pitch: 1 inch)
Recommended Screw: 8mm
Warning! Do not connect this terminal to AC power system neutral.

Two battery sensor cables are provided with each shelf. The cables are labeled
TB-1 terminate on connectors TB-1 and on the Detection Module. The positive bus
on the inter-cell connections of the battery strings for -48 VDC, or in between the
battery cells depending on whether the batteries are exiting or being installed with
the power shelf.

The Ambient Temperature Sensor is labeled TA and can be placed anywhere clear
of the rectifier fan flow. (The TA Sensor had already fix on the appropriate location
of the cabinet by factory, no required to install by customer of this item) The
Ambient Temperature Sensor TA is terminated to the back of the CSU to the
connector labeled Ambient Temp.

START - UP PROCEDURE
4.1
Initial Startup Preparation
Verify all connections prior to starting this section.
Warning! Ensure the input AC circuit breaker located at the AC service panel is
switched to the “Off” position.
Warning! Confirm the operating voltage before proceeding.
Warning! Ensure the frame ground is properly connected to a permanent earth
ground connection.
Warning! Ensure all the Load DC Circuit breakers located in the DC Distribution
Cabinet are switched to the “Off” position.
Failure to follow this sequence may damage the rectifier.
4.2
No Load Start-up
The shelf can be turned up without a load. The start-up procedure is as follows:
1. Switch all DC circuit breakers (load) to the “Off” position.
2. Make sure battery is not connected to the system Battery Bus.
3. Check the CSU for alarm status.
4.3
Basic Functional Verification
After shelf start-up, basic functional verification should proceed.
Check the monitor of CSU display.
4.4
Parameter Settings
Most parameters are pre-set at the factory and are listed on the shelf Test Report
included with each shelf. This section provides a general explanation for some
parameter may need changing.
4.4.1
Float/Equalize Voltage
Both Float and Equalize voltages are preset at factory and listed on the shelf Test
Report. The CSU controls the system settings and overrides the settings made on
each rectifier. If a different value is required, both SMR and CSU settings must be
identical.
4.4.2
Current Limit
The CSU controls the system current limit threshold by monitoring the total load,
the number of rectifiers in-service and the battery current. A parameter sets
