Installation and User Manual

2.3.1UPS Connections

Electrical connections and cabinet interconnection will vary depending upon the configuration and options selected with your Galaxy 4000 UPS system. Refer to the installation drawings supplied with your equipment.

Connecting Power Cable Connections:

To access the connection terminal blocks, open the right door to the Galaxy 4000 UPS. Remove the safety panel located in the lower right hand section of the unit. See Figure 2-1.

a.The ground and neutral conductors must be connected to the ground and neutral busbars, respectively. The input and output neutral are connected at the neutral busbar.

b.Connect the three conductors of the main AC source to terminal block TB1.

c. If bypass source is present, connect the conductors of the bypass AC source to terminal block TB3. If bypass source is not present, verify jumpers in place between TB1 and TB3.

d.Connect the three conductors supplying the load to terminal block TB2.

e.Connect the battery conductors to the positive and negative busbars.

f.Secure all cables with cable ties.

g.Put all panels and covers back in place.

2.3.2Main AC Input Connections

The connections to be made are the three phases, neutral, and ground cables from the utility AC power source to the UPS. The main AC input cables are terminated at the main input terminal block (TB1). See Figure 2-1.

IMPORTANT For single input (optional configuration), jumper cables are provided from terminal blocks TB1 to TB3.

2.3.3Bypass AC Input Connections (optional)

The bypass AC input cables are terminated at the bypass input terminal block (TB3). This option provides a separate AC input source for bypass operation. See Figure 2-1.

2.3.4AC Output Connections

The connections to be made are the three phases, neutral, and ground cables from the load to the UPS. The output cables are terminated at the output terminal block (TB2). See Figure 2-1.
