Preparing for Installation
• Personnel responsible for the application of safety-related programmable electronic systems (PES)
shall be aware of the safety requirements in the application of the system and shall be trained in
using the system.
• This product is grounded through the DIN rail to chassis ground. Use zinc-plated yellow-chromate
steel DIN rail to assure proper grounding. The use of other DIN rail materials (such as aluminum,
plastic, and so on) that can corrode, oxidize, or are poor conductors can result in improper or
intermittent grounding. Secure the DIN rail to the mounting surface approximately every 7.8 in. (200
mm), and use end-anchors appropriately.
When determining where to place the switch, observe these guidelines:
Before installing the switch, first verify that the switch is operational by powering it on and running

exceed 328 feet (100 meters).
For 100BASE-FX fiber-optic ports, the cable length from a switch to an attached device cannot
•
exceed 6562 ft (2 km).
• Operating environment is within the ranges listed in
• Clearance to front and rear panels meets these conditions:

–
Temperature surrounding the unit does not exceed 140°F (60°C).
•
Note
Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent

Front-panel LEDs can be easily read.
Access to ports is sufficient for unrestricted cabling.
Front-panel direct current (DC) power and relay connector is within reach of the connection to
the DC power source.
Top and bottom: 4.13 in. (105 mm)
Exposed side (not connected to the module): 3.54 in. (90 mm)
Front: 2.56 in. (65 mm)
When the switch is installed in an industrial enclosure, the temperature within the enclosure
is greater than normal room temperature outside the enclosure.
The temperature inside the enclosure cannot exceed 140°F (60°C), the maximum ambient
enclosure temperature of the switch.
