MGE GALAXY 5500 SINGLE UPS PARALLEL ACCESSORIES

[BillP]

Dear All,

I would like to know can these ups's be connected in parallel with same model? what accessories would be used to connect two ups's in parallel. Please respond ASAP, Many thanks in advance.

G55TUPSU60HS + G55TUPSU60HS = parallel accessory part no??

G55TUPSU80HS + G55TUPSU80HS = parallel accessory part no??

G55TUPSU120HS+ G55TUPSU120HS = parallel accessory part no??

Hi War,

As I mentioned before, these are the types of questions that need to go through EMEA sales directly for a quick answer. Some of this stuff is custom as well and cannot be provided via me. I have to go to through several people to dig up what I can so there is a big delay. Here is what I received though for this one.

If  2 x GX5500 Modular UPS's are ordered as a N+1 system they should come as standard with the paralleling cables which are long enough to connect the UPS's together via the bottom of the units.

If however there are 2 x UPS's on a site operating as Single modules, and they need to be put into parallel, they need to be MODULAR type units which have the parallel interfaces included.

(Unitary modules do not have this equipment and need additional modification kits in order to make them operate in parallel).

Cable part numbers

2 x 34001756SE (or 0W1-3400175600AD) are required - (Exchange Current) - (>10meters , Part on order 3440114300 with specified length)

1 x 34001755SE is required - (Can Bus) - (>10 meters needs to be ordered special through EMEA sales team - they have to be specially made to order, and as thus have no part number attributed to them.)

Dear Angela,

Thanks a lot for your reply. I wrote a very detailed reply but before sending mistakenly I dont know what key got pressed and that reply got vanished. I tried to bring it back again by pressing Ctrl+Z and history,  but I couldn't succeed. Now mood is not that good.

AnyWay, Now; Briefly:), I am thinking  that why MGE GALAXY 5500 UNITARY  UNITS are in USE??? I wanna show u a simplest comparison,

MODULAR UNITS VS UNITARY UNITS = PRICE DIFFERENCE = NO (only few hundred dollars, which means nothing)

MODULAR UNITS  = PARALLEL OPTION > JUST REQUIRED CABLES WITH MINIMUM COST

UNITARY UNITS = PARALLEL OPTION > REQUIRED FULL KIT WITH HIGHEST COST

So, What is the REAL benefit for these UNITARY MODELS? You know how effort I've done to get these parallel kits part number for

60kVA UPS: Parallel Kit = 34002210SE , 80kVA & 120kVA UPS: Parallel Kit = 34002211SE and if you see modular units there are just cables required which you have described in you reply.  Basically, I've chosen unitary units thinking that they should be very cheap or inexpensive as compare to modular units., but afterwards when customer asked for parallel option etc so I got to know what Pandora box I had opened.

If you know, any feature of unitary units which is not present in modular unit so please let me know. because I think apc should not show these units on their website because there is no price difference, and they only create confusion.

What you say???

Thanks dear for your effort and valuable response.

Regards,

War

Hi War,

I asked the product manager to comment. Here is what I received.

There is no feature set difference between the unitary and modular units. This is why the cost difference is minimal. It really comes down to what the customer needs.

• i.e. a N=1 system -order the modular.
• no redundancy required order single modules.(Unitary)

We give the ability to use the singular units in parallel to alleviate the cost for a customer who already has 2 unitary systems then decides they want redundancy without having to purchase a completely new UPS system.

hmmm.... ok...

My problem has been solved. Many thanks for you.

Quintessence from my side for this discussion.

Unitary units are only beneficial in the sense of PAST, the units which had been installed in past and still running, if they go for parallel option then KITS are available and no need to purchase new units. But, If somebody is going to quote MGE GALAXY 5500, do not go with unitary unit always go with modular unit. Otherwise, You might face difficulty.

Thanks for your ever green support.
