These hazards may include shock, energy, and/or burns. To avoid these hazards: a) The tasks should be performed in the order indicated. b) Remove watches, rings, and other metal objects. c) Prior to contacting any uninsulated surface or termination, use a voltmeter to verify that no voltage or the expected voltage is present. Check for voltage with both AC and DC voltmeters prior to making contact. d) Wear eye protection. e) Use double insulated tools appropriately rated for the work to be performed. f) For 400V DC input systems, do not work on an energized system without full arc flash and PPE protection.

Voltages

AC Input Voltages

Danger

DANGER! This system may operate from AC input voltage capable of producing fatal electrical shock. AC input power must be completely disconnected from the branch circuits wiring used to provide power to the system before any AC electrical connections are made.

Follow local lockout/tagout procedures to ensure upstream branch circuit breakers remain de-energized during installation. DO NOT apply AC input power to the system until all electrical connections have been completed and checked.

DC Input Voltages

Danger

DANGER! This system may operate from 400V DC input voltage capable of producing fatal electrical shock. DC input power must be completely disconnected from the branch circuits wiring used to provide power to the system before any DC electrical connections are made.

IB2 (Controller Interface Board) Connections

(if required) (Main Bay Only)

The IB2 (Controller Interface Board) provides connection points for digital inputs, programmable relay outputs, and temperature probes. The IB2 interface board is mounted inside the distribution

cabinet. Refer to Figure 20 .

Digital Inputs and Programmable Relay Outputs

Digital input and relay output leads are connected to screw-type terminal blocks located on the IB2. Recommended torque for

these connections is 2.2 in-lbs. Refer to Figure 22 for terminal

locations. Refer to Table 1

and Table 2 for pin-out information.

Digital Inputs

Connect up to eight (8) digital inputs to the IB2. Note that you must supply both paths for the digital input (either a positive or negative signal and the opposite polarity return path). Observe

proper polarity. Refer to Figure 22

for terminal locations and Table

1 for pin-out information.

Note:

-48V is factory wired to the Digital Input #8 (-) terminal for your convenience and function predefined for ESTOP.

Customer-furnished system ground applied to terminal Digital

Input #8 (+) activates the ESTOP function. The ESTOP function shuts down and locks out the rectifiers or 400V DC input converters, opens the LVD’s, and shuts down the optional -48V to +24V DC converters. When the ESTOP signal is removed,

LVD’s close (if battery present) and -48V to +24V DC converters restart. To restart the rectifiers or 400V DC input converters; turn input power to the rectifiers/converters OFF, wait 30 seconds or more (until the LEDs on the module extinguish), then turn input power to the rectifiers/converters

ON.

The digital inputs can be programmed to provide an alarm when the signal is applied (HIGH) or removed (LOW). Refer to the ACU+

Instructions (UM1M820BNA or UM1M820DNA400) or NCU

Instructions (UM1M830BNA) for programming information.

Digital Input Ratings: Refer to the following. a.

Maximum Voltage Rating: 60V DC. b.

Active High: > 19V DC. c.

Active Low: < 1V DC.

The digital inputs may be preprogrammed for specific functions.

Refer to the configuration drawing (C-drawing) supplied with your system for your system’s specific configuration.

Programmable Relay Outputs

The IB2 provides eight (8) programmable alarm relays with dry

Form-C contacts. Connect up to eight (8) relay outputs to the IB2.

Refer to Figure 22

for terminal locations and Table 2 for pin-out

information.

Note:

The relay assigned to “Critical Summary” alarm (relay 1 by default) will operate in the “Fail Safe Mode”. “Fail Safe Mode” means Relay 1 is de-energized during an alarm condition, opening the contacts between the C and NO terminals, and closing the contacts between the C and NC terminals.

The remaining 7 relays energize during an alarm condition, closing the contacts between the C and NO terminals, and opening the contacts between the C and NC terminals.

Refer to the ACU+ Instructions (UM1M820BNA or

UM1M820DNA400) or NCU Instructions (UM1M830BNA) for programming information.

Relay Ratings: Refer to the following. a.

1A Steady State @ 30V DC. b.

3A Peak @ 30V DC.

The relays may be preprogrammed for specific functions. Refer to the configuration drawing (C-drawing) supplied with your system for your system’s specific configuration.

Temperature Probes

Note:

Each temperature probe consists of two pieces that plug together to make a complete probe. See SAG582127000 for part numbers and descriptions.

Temperature probes are connected to the IB2 (Controller Interface

Board) and/or optional EIB (Controller Extended Interface Board)

mounted inside the distribution cabinet. See Figure 22

and Figure

24 .

Up to two (2) temperature probes can be connected to the IB2. Up to two (2) additional temperature probes can be connected to the optional EIB. Any combination of the four (4) temperature probes can be programmed to monitor ambient temperature and/or battery temperature. A temperature probe set to monitor battery temperature can also be used for the rectifier battery charge temperature compensation feature, or the battery charge temperature compensation feature can be programmed to use the average or highest value of all battery temperature probes. The battery charge temperature compensation feature allows the controller to automatically increase or decrease the output voltage of the system to maintain battery float current as battery temperature decreases or increases, respectively. Battery life can be extended when an optimum charge voltage to the battery with respect to temperature is maintained. A temperature probe set to monitor battery temperature can also be used for the BTRM

(Battery Thermal Runaway Management) feature. The BTRM feature lowers output voltage when a high temperature condition exists to control against battery thermal runaway.

The temperature sensor end of the probe contains a tab with a

5/16” clearance hole for mounting.

A temperature probe programmed to monitor battery temperature should be mounted on the negative post of a battery cell to sense battery temperature. A temperature probe used for battery charge temperature compensation and/or BTRM (Battery

Thermal Runaway Management) should also be mounted on the negative post of a battery cell. A temperature probe programmed to monitor ambient temperature should be mounted in a convenient location, away from direct sources of heat or cold.

• Converters are installed in 588705000 List 40, List 41, and 42 shelves.

Rectifier or converter modules can be inserted or removed with power applied (hot swappable).

Note:

The rectifier or converter module locks into the module mounting shelf through a latch located on the underside of the module. The latch and module handle are interactive. Push the handle into the module’s front panel, and the latch will pop out from the module bottom. Click the handle to pop it out from the module’s front panel, and the latch will retract back into the module. The latch

mechanism is shown in Figure 54 .

Warning

WARNING! To prevent damage to the latching mechanism, ensure the handle is in the open position when installing or removing a module. NEVER hold the handle in the closed position when installing a module into a shelf.

Note: 588705000 List 32 Rectifier Mounting Shelves Only (3-Phase Input):

One three-phase input feeds the three rectifier modules on the lefthand side of the shelf. The second three-phase input feeds the modules on the right-hand side. To maintain phase balance, install rectifier modules in groups of three; that is, fill all three mounting positions on the left and/or all three on the right.

PROCEDURE

1.

3.

Place the module into an unoccupied mounting position without sliding it in completely. Rectifiers modules can be installed in any mounting position of each module mounting shelf. Converters modules can be installed in any of the three far right

mounting positions of each module mounting shelf. See Figure 55 .

4.

Loosen the captive screw on the module’s handle. Pull the handle down out from the module’s front panel (this will also retract

the latch mechanism). See Figure 55 .

5.

Push the module completely into the shelf.

6.

Push the handle up into the module’s front panel. This will lock the module securely to the shelf. Tighten the captive screw on the handle.

Board, optional EIB Interface Board, and optional SM-DU+

Shunt Interface Board.

Note:

When setting total rectifier or total converter current limit, the set point to each unit is the total set point divided by the number of units. For example, if the system contains five rectifiers and the current limit is set to 150 amps then each rectifier has a current limit set point of 30 amps. If one or more rectifiers or converters are removed or fail it will take several seconds for the individual set points to the remaining rectifiers or converters to be reset. In the example given, if one rectifier is removed the current limit set point will drop to 120 amps (30 amps times four remaining rectifiers) until the controller can send updated set points to the remaining rectifiers. This takes a couple communication cycles (several seconds) after which each rectifier would have a new set point of 37.5 amps for a total of 150 amps. The total current limit of the rectifiers and converters should not be set such that the loss of the redundant rectifiers or converters will cause this temporary set point to drop below the actual maximum expected load. If batteries are used on the rectifier output, the batteries should support the load until the current limit set points can be re-established due to loss of a rectifier.
