Environmental Considerations and Cautions
The following is a list of environmental considerations that will ensure safe and
efficient operation of your Digi CM:
•
Do not position the Digi CM near high-powered radio transmitters or
electrical equipment, such as electrical motors or air conditioners.
Interference from electrical equipment can cause intermittent failures.
•
Avoid exceeding the maximum cabling distances discussed in the online
cable guide.
•
Do not install the Digi CM in areas where condensation, water, or other
liquids may be present. These may cause safety hazards and equipment
failure.
For DC powered equipment:
•
Install equipment in Restricted Access Areas only (dedicated equipment
rooms/closets) in accordance with Articles 110-16, 110-17, and 110-18 of
the National Electrical Code, ANSI/NFPA 70.
•
Connect equipment to a DC supply source (reliably earthed) that is
electrically isolated from the AC source.
•
Directly connect the equipment chassis to the DC supply systemgrounding
electrode conductor or a bonding jumper from a grounding terminal bar (or
bus) that is connected to the DC supply system grounding electrode
conductor.
•
Contain equipment that has a connection between the grounded conductor
of the same DC supply circuit, the grounding conductor, and also the point
of grounding of the DC system in the same immediate area. Do not ground
the equipment elsewhere.
•
Locate the DC supply source within the same premises as the equipment.
•
Route away and secure all DC input wiring from sharp edges to prevent
chaffing as well as provide strain relief.
•
Provide a readily accessible disconnect device and protective device a
fixed wiring for a DC power supply suitable for the specified rated voltage
and current. Disconnect and protective devices to be rated 2A Amps
maximum.
Note:
The Digi CM is intended to connect to networking devices. Do not attempt con-
necting to a telephone line.
Safety Instructions
CAUTION: Do not operate your Digi CM with the cover removed.
•
To avoid shorting out your Digi CM when disconnecting the network cable,
first unplug the cable from the equipment and then from the network jack.
When reconnecting a network cable to the equipment, first plug the cable
into the network jack and then into the equipment.
•
To help prevent electric shock, plug the Digi CM into a properly grounded
power source. The cable is equipped with 3-prong plug to help ensure
proper grounding. Do not use adapter plugs or remove the grounding
