Installation Instructions
Secure Racking
If Secure Racked units are installed in a closed or multi-unit rack assembly, they may
require further evaluation by Certification Agencies. The following items must be
considered.
1. The ambient within the rack may be greater than room ambient. Installation
should be such that the amount of air flow required for safe operation is not
compromised. The maximum temperature for the equipment in this environment is
60°C. Consideration should be given to the maximum rated ambient.
2. Installation should be such that a hazardous stability condition is not achieved due
to uneven loading.
Input Supply
1. Check nameplate ratings to assure there is no overloading of supply circuits that
could have an effect on overcurrent protection and supply wiring.
2. When installing 48 VDC rated equipment, it must be installed only per the following
conditions:
A. Connect the equipment to a 48 VDC supply source that is electrically isolated
from the alternating current source. The 48 VDC source is to be connected to
a 48 VDC SELV source.
B. Input wiring to terminal block must be routed and secured in such a manner
that it is protected from damage and stress. Do not route wiring past sharp
edges or moving parts.
C. A readily accessible disconnect device, with a 3 mm minimum contact gap,
shall be incorporated in the fixed wiring.
Grounding
Reliable earthing of this equipment must be maintained. Particular attention should
be given to supply connections when connecting to power strips, rather than direct
connections to the branch circuit.
No Serviceable Parts Inside; Authorized Service Personnel Only
Do not attempt to repair or service this device yourself. Internal components must be
serviced by authorized personnel only.

Warnings and Cautions
Disconnect Power
If any of the following events are noted, immediately disconnect the unit from the outlet
and contact qualified service personnel:
1. If the power cord becomes frayed or damaged.
2. If liquid has been spilled into the device or if the device has been exposed to rain
or water.
Two Power Supply Cables
Note that some DSM Series units feature two separate power inlets and a separate
power supply cable for each power inlet. If your DSM unit includes two power inlets,
make certain to disconnect both power supply cables from their power source before
attempting to service or remove the unit.
Modem Cables
CAUTION: To reduce the risk of fire, use only No. 26 AWG or larger (e.g., 24 AWG) UL
Listed or CSA Certified Telecommunication Line Cord.
ATTENTION: Pour réduire les risques d’incendie, utiliser uniquement des conducteurs
de télécommunications 26 AWG au de section supérieure.
