FAQ
Does the 2033A, 2033C and 2033D Series UPS require a DC breaker?

Technically No. The UPS has a DC contactor that opens and close the DC link.
But in some cases NEC requires a means of disconnect, i.e. remote battery system.

What are the benefits of ISO-Redundant UPS system?

Reduce the chances of dumping the critical load.
Increase reliability.
In comparison to parallel redundant systems, the peripherals are less costly.

How many cables can connected to the DC bus terminals?

Two cables back-to-back per mounting bolt hole when high press connectors are used. Possibly up to four cables per mounting bolt hole if special mechanical lugs are used.

Do our UPS systems comply with FCC?

7011A, 6-12kVA FCC Rules Part 15 Subpart B Class A.
2033C FCC Rules Part 15 Subpart B Class A.
2033D FCC Rules Part 15 Subpart B Class A.

Does the UPS have surge withstand?

Yes, meets IEEE C62.41 Category B.

Does 2033C Series UPS have dual input?

No

Which UPS Series have internal batteries?

The single phase 7011A Series has internal batteries.
The 2033C Series has internal batteries for 10kVA to 20kVA capacity units.
The 2033D Series has internal batteries for 30kVA capacity units.

Are the UPS transformers shielded?

Yes, the UPS output isolation transformers (device No.TRI) have a shield between the primary and secondary winding.

Does the UPS have Ground Fault Detection?

No, the Mitsubishi UPS systems do not have a DC ground fault detection feature.

Are the UPS systems designed for Seismically Active installations?

Refer to Seismic Design document listed on the website.

How do you size an Engine-Generator that is the backup source for a Mitsubishi UPS system?

Engine-Generator (E-G) to UPS compatibility is dependent on the Generator Capability Curve and the E-G Controls. As a guide the following recommended minimum ratios are provided. It is advisable to consult with the E-G manufacturer.

UPS Series

Ratio, Generator(kW) : UPS(kVA)

2033C1 : 1
2033A1 : 1
97001 : 1
980AD1.1 : 1

Refer to 2033 Series Generator compatibility and 9800AD Generator compatibility docuemnts on our website. What is the maximum battery charge current for the UPS?

Refer to the Max. Battery Charge Current document listed on our website for the maximum battery charge current for the various Mitsubishi Electric UPS systems.

Is the Copy of the ISO9001 Certificate available?

Yes. See our website.

How do you calculate battery run time?

First you need to calculate the kW required to operate the UPS at 100% load.
Next, depending on the battery manufacturer, the kilowatts per battery (kWb) or kilowatts per cell (kWc) is calculated. You can use our Battery Runtime Finder listed on our website, or contact our engineering department at (847)478-2612 with further battery questions.

Which UPSs have the UL-924 Listing for Emergency Lighting?

2033C 10kVA - 50kVA.
2033A 30kVA - 75kVA.
7011A 6kVA - 12kVA.

What is the Input Power Factor of the Mitsubishi UPS?

Refer to 2033 Series Generator compatibility and 9800AD Generator compatibility docuemnts.

What are the kBTU/Hr @ no load for Mitsubishi UPS's?

Refer to the UPS No-Load docuemnt listed on our website.

What is Mitsubishi doing concerning factory testing? What can a client see in Japan?

Mitsubishi Electric Power Products, Inc performs all UPS system testing in the Kobe, Japan. Test reports for 100KVA-750KVA UPS's available upon request.

What is the Non-Operating and Storage specs for the UPS?

According to UPS specifications it is 20 degree C to +75 degree C.

The UPS system shall not be damaged, nor operate inadequately , when operated in the vicinity of a hand held radio transceiver, 5 Watts, 50-500 MHz range transmitting within two (2) feet of the equipment with doors open and/or closed.

Mitsubishi is tested three frequencies.
a) 5W 460MHz.
b) 5W 372MHz.
c) 5W 150MHz

POWER DEMAND

Sets the input current and kW limit of UPS when the external contact is close.

IR COMPEN

Used to automatically adjust the Inverter output voltage to compensate for line loss. Expressed as a percentage. For example, if set at 3%, at no load the Inverter output voltage will be at nominal. At 100% load, the Inverter output voltage will be at nominal + 3%.

SLEW RATE

Sets the rate at which the Inverter will change frequency to match a change in bypass frequency. Expressed in Hertz per second
