UPS Connections
Standard Unit with 120V Isolation Module Figure 2 shows the standard unit, consisting of one electronics module and one battery module, with the addition of the 120V isolation transformer module.
Figure 2 : 120V Isolation Transformer Module Configuration
The modules do not have to be stacked for the unit to operate; however, if the modules are to be stacked please refer to the 1700 Series user manual for instructions on interlocking modules.
To connect the modules electrically follow these steps:
1.The power cord from the electronics module must be plugged into the output receptacle on the back of the option module (see figure 1).
2.The input power cord from the option module must be plugged into a power source (see figure 1).
The battery power cord must also be plugged into the electronics module for the system to provide backup power (refer to the 1700 Series user manual or the battery module installation instructions for instructions on connecting the battery module).
Note: No more than three modules should be stacked in any configuration. If the option module is being used with a system that has an expansion battery module at least one module must be placed beside the others.
Stacking four modules could result in a tipping hazard.
Standard Unit with 230V IO Module
Figure 3 shows the standard unit, consisting of one electronics module and one battery module, with the addition on the 230V transformer module.
Figure 3: 230V Transformer Module Configuration
The modules do not have to be stacked for the unit to operate; however, if the modules are to be stacked please refer to the 1700 Series user manual for instructions on interlocking modules.
To connect the modules electrically follow these steps:
1.Plug the output power cord from the transformer module into one of the output receptacles on the back of the electronics module (in the case of the 2.4kVA model the cord can only be plugged into the 20A outlet, see figure 1).
2.Next, plug the power cord from the electronics module into the output receptacle on the back of the transformer module (see figure 1).
3.The input power cord from the transformer module must be plugged into a power source (see figure 1).
The battery power cord must also be plugged into the electronics module for the system to provide backup power (refer to the 1700 Series user manual or the battery module installation instructions for instructions on connecting the battery module). The unused receptacles on the back of the electronics module are still active, but they are providing 120V power, not 230V. All 230V power must be drawn from the output receptacles on the back of the option module.
