Expanding HiPath 3000
9.2.4.4 Expansion Cabinet Rack ECR With Batteries
When using the UPSM or the UPSC-DR as the uninterruptible power supply unit, you need to
install additional batteries in the ECR.
The ECR and batteries are packaged separately and included in the delivery. The batteries
should be installed as described in Section 9.2.4.4.1. Only use batteries approved for HiPath
3000.
Figure 9-5 shows the position of the four batteries inside the ECR.
The circuit diagram below illustrates the cable run between the batteries in the ECR and the
power supply unit of the system (UPSM for HiPath 3700, UPSC-DR for HiPath 3500 and HiPath
3300). The connection cable between the expansion cabinet rack ECR and the system cabinet
is also provided.

Before opening the housing, disconnect the ECR from the power supply by
● setting the switches for battery voltage and line voltage on the ECR’s front panel
