When rack-mounting this equipment, the rack should be appropriately earth-grounded.
3.2 AC POWERED CHASSIS SITE PREPARATION
Power source should be available within 5 ft. of the chassis and installed per the National Electrical Code, ANSI/NFPA-70.
Model 1020-1 requires 100-240VAC, 0.4Amp, 50/60Hz. Appropriate overloading protection should be provided on all AC power
source outlets utilized.
The standard operating temperature of this equipment is 0 to 50 degrees C. If installed in a closed or multi-chassis rack
assembly, the operating ambient temperature of the rack must not exceed the maximum rated 50 degrees C temperature. For
wide temperature models, the operating temperature must not exceed 60 degrees C.
Installation of the equipment should be such that the air flow in the front and back of the chassis is not compromised or
restricted.
Installing this equipment into a rack in such a way as to make it unstable may cause injury or death. Always make sure that
the rack is properly secured, stable, balanced and designed to carry the weight and weight distribution of this equipment.
Never use this equipment to carry any weight except its own. Never use it as a shelf to support the weight of other
equipment.
Attach the AC power cord to the back of the chassis and plug into the AC outlets. The Power LED on the front of the chassis
will illuminate as well as the Power LED on any installed modules.
NOTE: The fans will not operate until the internal ambient temperature reaches appropriately 50° C. The fans will
turn off once the internal ambient temperature drops below appropriately 40° C.

3.3 DC POWERED CHASSIS SITE PREPARATION
Power source should be available within 5 ft. of the chassis. The over current protection for the connection with centralized DC
shall be provided in the building installation and shall be a UL listed breaker rated at 15 Amps, and installed per the National
Electrical Code, ANSI/NFPA-70.
Model 1025-1 requires 36-60VDC/1.0 Amps power. Model 1026-1 requires 18-36VDC/2.0 Amps power. Appropriate overloading
protection should be provided on all DC power source outlets utilized.
WARNING: Only a DC power source that complies with
safety extra low voltage (SELV) requirements can be
connected to the DC-input power supply.
