1 Introduction

1.1 Scope of the Manual

This instruction manual explains the installation, interconnection, and operation of Argus Technologies’ INEX Inverter System.

1.2 Product Overview

INEX inverter series is an integrated telecommunication AC power system, including inverter, static switch, LCD controller, and interface modules. With versatile “building block” design and N+1 redundant configuration, INEX inverter system facilitates complex telecommunication and industrial power demands.

INEX series DC to AC inverter module is available for 1000VA (800W) or 1500VA (1200W) to convert -48Vdc input to 120Vac or 230Vac output at 50Hz or 60Hz. The inverter module is “hot swappable” meaning it can be inserted or removed from the shelf without cutting power to or from the system.

A universal 19” shelf is designed to parallel connect and synchronize all INEX inverter models. With this shelf, INEX series employs N+1 redundant configuration to output power maximum of 12kVA for 120Vac models and 18kVA for 230Vac models, and to operate in N+1 redundant mode for optimization. INEX “all master” dynamic mechanisms automatically share and re-organize critical loads to further prevent interruption if one or more inverter modules fail.

INEX selective static transfer switch (STS) provides automatic instantaneous load transfer, which further secures uninterrupted operation of sensitive electronic equipment.

The INEX system controller, equipped with a DSP microprocessor, gives real-time system status through comprehensive LCD/LED indication, and allows program settings through the display panel. A communication interface module provides local or remote control and monitoring of the system.

4 Wiring and Connections

This chapter provides notes on cable sizing and cabling details with respect to the Argus INEX 1000/1500 Inverter System.

4.1 Safety Precautions

WARNING Ensure all power sources are OFF during wiring. Disconnect battery cables from battery.

Before working with any battery or power system/distribution center, follow these precautions:

• Remove all metallic jewelry; e.g., watches, rings, metal rimmed glasses, necklaces.

• Wear safety glasses with side shields (and prescription lenses if necessary) at all times during installation.

The installer should follow all applicable local rules and regulations for electrical and battery installations; e.g., CSA, UL, CEC, NEC, OSHA, and local fire codes.

Use OSHA approved insulated hand tools.

4.2 Tools Required

Various tools are essential for product installation. Use this list as a guide:

• Slot head screwdrivers (blade sizes: 1/4”, 1/8”, 1/16”)

• Philips head screwdriver, #2 (tip size 3/16”)

• Digital voltmeter equipped with test leads

• Adjustable 48Vdc load (optional)

• Cutters and wire strippers

• Crimping tool (optional for large gauge wire)

Page 28

6. Replace rear cover(s) once all connections have been

completed.

7. Screw the system ground wire on the rear cover with the

supplied cross hex-washer type nickel screw.

CAUTION STS is not hot swap without MBS. When installing STS module with MBS it is not necessary to turn off the system. However, the

incorrect install/removal action will damage the STS module frame because of the safety lock of the MBS.

Proceed as follows: put switch at MBP or IBP position (Determined by mains and inverter output status) as shown:

MBP position:

4.8.1 Position Status of MBS

The operation mode of STS is closely associated with the position of MBS. The MBS has two main connectors and three assistant connectors. The signals generated by three assistant connectors are passed to DSP for position status detection. There are five valid positions:

1. MBP –

UmUains UbUyUpUass

2. MSS – UmUains UsUtatic UsUwitch (for mains maintenance)

3. NORM –

4. ISS –

5. IBP –

UnormUal operation UiUnverter UsUtatic UsUwitch (for inverter maintenance) UiUnverter UbUyUpUass

STS will continuously detect the position of MBS in order to decide the transferring action between different modes.

IBP position:

When the STS is powered on, it will judge whether the present position of MBS is valid. If the status is invalid, STS will consider MBS not well connected, and it will not enter any types of operation mode until the detection signal becomes normal.

If MBS is changed when STS runs at one of the five valid positions, and this change happens between two adjacent positions, the STS will transfer to different mode based on current status. Otherwise, the STS will not take any action.

For example, if MBS is set at P3, STS will take action when MBS is turned to P2 or P4.

Argus Technologies Ltd. 014-114-C0 Rev D WC

Page 29

NOTE: Be sure not to change MBS position immediately when STS is inserted into the rack, wait at least five seconds if

you want to change it. When you change its position you must confirm that you keep MBS at one position more than one second in order for MCU of STS has enough time to detect MBS position via MBS auxiliary contacts (CN1).

9 Troubleshooting

If the system fails to operate properly after having the installation and setup of the system thoroughly reexamined, use the following troubleshooting table to determine the probable cause(s) and solution(s) to resolve error conditions. For unlisted error conditions, please contact your local dealer for technical assistance.

Error Condition Possible Cause Recommendation

Improper position of nylon guide pin. Inverter module cannot be properly inserted.

No AC output and all LEDs off.

No AC output. Both green and yellow LEDs flicker. No AC output. Both yellow and red LEDs are on.

No AC output. Red LED is on.

Red LED blinks fast.

AC output exists with yellow LED flickering. AC output exists and yellow LED is on.

Inverter continuously delivers power, but with red LED flickering slowly.

Insertion of non-inverter module.

Lack of input power.

Mismatch of inverter modules.

Inverter self-diagnosis.

Load exceeds 125%.

1. Input wiring is connected in reverse (i.e.

reverse polarity).

2. Output voltage is out of operating range.

3. Inverter output is shorted.

4. Negative Power Protection.

1. Inverter fails to soft start.

2. Inverter temperature rises beyond the

temperature limit.

Input voltage is out of operating range. Ensure input voltage is between 45 to 58Vdc.

Load is over 100% but below 125%.

Failure of EEPROM.

Fans failure.

Refer to Section 3.1 to insert the nylon guide pin to correct position. Check if the inserted module is not inverter module. Inverter shelf holds only inverter modules. Ensure input cables are all firmly connected to power source. Check if power source is not yet switched on, or is low in power. Ensure inserted inverter modules have the same specifications. Inverter self-diagnosis takes a few seconds. LED turns to a solid green light after the completion of self-diagnosis.

Ensure the load is no higher than 100% of the total power rating. Reduce as required.

Ensure input cables are connected to correct polarity (positive to positive, negative to negative). Adjust voltage to ensure that the connected device is within the inverter output voltage range. Turn off the input power source to remove all short circuits.

For multi-shelf system, any jumper insertion on

JP2 connector would obstruct parallel connections. Remove jumper from JP2 connector.

For single-shelf system, jumper on JP2

connector pools two inverter modules. Ensure there is a jumper on JP2 connector. Reboot the inverter system by switching off and on the input power source.

Leave inverter idle to cool down for few minutes.

Ensure the load is no higher than 100% of the total power rating. Reduce as required. Reboot the inverter system by switching off and on the input power source. Check if the fans are locked or fail to work. If fan is locked, remove the obstruction; if fan fails to work, replace the fan.
