Chapter 1 : Product Introduction

The Delta Maintenance Bypass Box (MBB) is applicable to Delta Amplon UPSs:

RT-15K3P and RT-20K3P. The MBB provides AC input power to the UPS and

connects the output of the UPS to the critical loads and is configurable for single-

phase or three-phase output to suit your needs. When your UPS needs

maintenance, you can switch on the MBB’s manual bypass switch to let the

power be transferred from the inverter output to the manual bypass output to

ensure continuous power supply to your critical loads when the UPS is under

maintenance. Product Introduction

Important Safety Instructions

2.1. Safety Instructions

Installation Warnings

• Before installation and usage, please read this User Manual thoroughly.

This will help you to use the product correctly and safely.

• Install the MBB in a well-ventilated area, away from excess moisture, heat,

dust, flammable gas or explosives.

• To avoid fire accidents and electric shock, please install the MBB in an

indoor area free of conductive contaminants and the temperature and

humidity must be well-controlled. For the temperature and humidity

specifications, please refer to Appendix 1 : Technical Specifications.

• Leave adequate space (at least 50 cm) around all sides of the MBB for

proper ventilation.

Connection Warnings

• The MBB must be well grounded due to a possible risk of current leakage.

• The installation of upstream and downstream protective devices is highly

recommended when the MBB is connected to the UPS.

• The protective devices connected to the MBB must be installed near the

MBB and must be easily accessible for operation.

•

If you need to move the MBB or perform re-wiring, please turn off the AC

input power. Otherwise, the output end might still be energized, which might

cause electric shock.

Usage Warnings

• To ensure reliable operation of the MBB and to protect the MBB from

overheating, the slits and openings in the MBB must not be blocked or

covered.

• Before usage, you must allow the MBB to adjust to room temperature for at

4



least one hour to avoid moisture condensing inside the MBB.

• Do not pour and splash any liquid on the MBB. Do not insert any object into

the MBB’s slits and openings. Do not put beverage containers on or around

the MBB.

• Do not apply any cleaning liquid or cleaning spray to the MBB. Before

cleaning, please make sure that the input power cables have been

unplugged.

• All maintenance services must be performed by qualified service personnel.

• Forbid opening or removing the cover of the MBB by yourself to avoid high

voltage electric shock.

• You must contact qualified service personnel if either of the following events

occurs:

1. Liquid is poured or splashed on the MBB.

2. The MBB does not run normally after the instructions in this User Manual

are carefully observed.

2.2. Standard Compliance

 IEC/EN 62040-1

2.3. Storage

• Prior to installation

If the MBB needs to be stored prior to installation, it should be placed in a

dry area. The allowable storage temperature and relative humidity (non-

condensing) are -15°C ~ +55°C and 5 ~ 95% respectively.

• After usage

Remove all equipment from the MBB, and store the MBB in a dry and well-

ventilated area at a temperature between -15°C and +55°C and at a relative

humidity (non-condensing) between 5 ~ 95%.

Chapter 6 : Connection

6. Connection

To connect the UPS with the AC source, bypass source and critical loads via the

MBB, the user should connect the UPS with the MBB first; then, connect the

MBB with the AC source, bypass source and critical loads.

NOTE：

1. User can decide whether to adopt single power source or dual power

source and single phase or three phase, which would influence the ways

of wiring configuration. For more details, please refer to Chapter 6.3.1 ~

Chapter 6.3.4.

2. Regarding the connection between the UPS and the battery pack,

please refer to Delta Amplon RT Series 15/ 20kVA UPS User Manual and

the Delta battery pack User Manual.

6.1. Pre-connection Warnings

The circuit breaker or other protective device must be installed at the AC power

input. Please follow Delta Amplon RT Series 15/ 20kVA UPS User Manual to

install the input protective device.

6.2. UPS Model Without Power Cables

MBB should be connected to the UPS with the power cables. If the UPS model

user originally purchased does not have the power cables installed before

shipment, the user should use the three power cables provided in the MBB’s

package to complete the connection with the UPS. The power cables to be

connected include the main input, bypass input and output cables. Please follow

the steps below to perform the power cable connection with the UPS; the

connection should be performed by qualified service personnel.

1. There are an upper cover at the rear of the UPS and three knockout covers on

UPS’s rear panel, remove them as shown in Figure 6-1. After removing them,

you can see the UPS wiring terminals from the top.

(Figure 6-1: Remove the Upper Cover at the Rear of the UPS and the Three

Knockout Covers from the UPS’s Rear Panel)

2. Please follow step ❶ to step ❸ below to connect the three power cables to the

UPS wiring terminals (the AC input terminals, the bypass input terminals, the UPS

output terminals and the grounding terminal). Use three cable glands (user-

supplied) to firmly fix the cables on the UPS.

Step ❶ : Fix the AC input power cable (4 pins) on AC input terminals of UPS.

Please note that the 4 pins of the main input power cable should be connected to

the right position of terminals (mL1, mL2, mL3 and N) as shown in Figure 6-2.

8. Maintenance Bypass

Follow the steps to let the output load powered by manual bypass when UPS

needs maintenance.

1. Check the UPS is at bypass mode, if not, press and hold the UPS’s ON/

OFF button for 3 seconds, release it after you hear one beep, use the

Scrolling Up or Down button to select 'Yes' and press the Enter button to

confirm your selection. The inverter will be off and the UPS will transfer to

run in bypass mode.

2. Loosen 3 screws and you can remove the warning cover of the manual

bypass switch. Please see Figure 8-1.

(Figure 8-1: Loosen 3 Screws from the MBB)

32



3. Under the cover plate, there is a manual bypass detector (see Figure 8-2)

that will be automatically activated to send the UPS a message of

transferring into bypass mode once the cover plate is removed. After you

confirm that the UPS has been run in bypass mode, turn on the manual

bypass switch. Now, the connected loads are being powered by utility

power. Please see Figure 8-2

(Figure 8-2: Turn on the MBB Manual Bypass Switch)

4. Disassemble the provided cover on the three power cables (You can refer to

Figure 6-12).

5. Disconnect the main input cable and bypass input cable first to turn off the

output of UPS then disconnect the output cable and the MBB
