Electrical Specifications

Table 2-1: Electrical Specifications for the Galaxy 4000.

NOTE: Interrupted Transfer to Bypass Source:

If the bypass source is beyond the conditions stated below, the UPS will make an interrupted transfer (not more than 100 msec. in duration).

1.

Bypass voltage greater than +15%, -15% from the UPS rated output voltage.

2.

Bypass frequency greater than ±2 Hz from the UPS rated output frequency.

2.3

Electrical Connections

CAUTION

Only an authorized electrical professional should access electrical connections.
A severe shock hazard exists.

The ONLY user serviceable items in the Galaxy 4000 unit are:

A.

The main and bypass power connections.

B.

The load connection.

C.

Any cable connection to external or auxiliary modules.

D.

The communication card options.

The access method for connections made to the communication cards is clearly seen when the front right door to

the Galaxy 4000 unit is opened. However, access to the main, bypass and load connections is made through the

removal of the safety panel located in the lower right of the Galaxy 4000 (with the right door open). This safety panel

is removed by first removing the screws securing the panel. It can then be removed by lifting the safety panel away

from the unit.

CAUTION

Before making any electrical connections, verify that all battery disconnect circuit
breakers (CB1) are in the "off" position. Customer-supplied upstream protective
devices and distribution circuits should be OFF.
