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.

2.3Electrical 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.
