Expansion Cabinet Rack ECR With Batteries and EPSU2-R
If the internal system power supply unit for HiPath 3500 or HiPath 3300 does not provide
enough power for the overall telephone configuration (corded and cordless telephones), an ad-
ditional power supply is necessary. In this case, the EPSU2-R external power supply unit
should be installed in the ECR.
Figure 9-7 shows the position of the EPSU2-R inside the ECR.
The block diagram below illustrates the cable run between the EPSU2-R and the batteries in-
side the ECR and the power supply unit of the system (UPSC-DR). The connection cable be-
tween the expansion cabinet rack ECR and the system cabinet is also provided.

Danger
An expansion cabinet rack (ECR) equipped with an external power supply unit
(EPSU2-R) may only be operated if the housing is closed.
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
to "Off".
●
removing the battery fuse on the ECR front panel and
●
unplugging all power and connection cables.
