4 Installation
This section describes how to install the base station in a standard 19-inch 
rack or cabinet. It also provides some general information on safety 
precautions and site requirements. We recommend that you read the entire 
section before beginning the installation.
4.1 Personal Safety
4.1.1 Lethal Voltages
The base station may be fitted with an internal AC power supply unit. If an 
internal AC power supply unit is fitted, a standard ICE AC power connector 
is fitted in the rear panel of the base station (refer to “AC Power 
Connection” on page 66).
Warning!! The internal AC power supply unit contains 
voltages that may be lethal. Refer to the ratings 
label on the rear of the base station. The internal 
AC power supply contains no user-servicable 
parts.
Important Wrong mains voltage! Before connecting to the AC power 
connector, ensure that the internal 115V/230V voltage 
mains selector switch is set to the correct mains voltage.
The voltage selector switch is located under the base station cover. (Refer to 
“Setting the AC Mains Input Voltage” on page 50.)
The base station must be installed so that the rear of the base station is 
located in a service access area. The internal AC power supply unit must be 
connected to the mains supply source by trained personnel in accordance 
with local and national regulations.
Ensure that all power sources (AC and
 DC) are disconnected 
before opening the base station.
