Chapter 3: Installing the Switch

Installing the Switch on an Indoor Wooden Wall
This section contains the procedure for installing the switch on a wooden
wall in a protected, indoor environment.
The switch does not require an enclosure when installed in most
indoor environments.
The switch must be installed in a UL Listed or Nationally Recognized
Test Lab enclosure when used in a Measurement, Control, or
Laboratory indoor environment, as specified in UL/EN/IEC 61010-1
and 61010-2-201.
The IE340L-18GP switch is not compliant with UL/EN/IEC 61010-1
and 61010-2-201 and must not be installed in a Measurement,
Control, or Laboratory environment.
The IE048-480 power supply and other non-compliant UL/EN/IEC
61010-1 and 61010-2-201 power supplies must be installed in fire
protection enclosures when installed on walls of combustible
material (e.g., wood). Additionally, the floor area directly below the
power supply should be non-combustible (e.g., metal or concrete)
and be free of combustible material (e.g., paper, plastic, or wood).
The device should be installed on the wall by a qualified building
contractor. Serious injury to yourself or others or damage to the
equipment may result if it is not properly fastened to the wall.
E105
Allied Telesis recommends using a plywood base when installing the
switch on a wall with wooden studs. The base allows you to mount the
device on two studs in the wall. (A plywood base is not required for a
concrete wall.) Refer to Figure 22 on page 74.
