Warnings and Cautions:
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.

CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only with same
or equivalent type recommended by the manufacturer. Discard used batteries according to the
manufacturer's instructions.
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.
