SAFEGUARDS

Electrical energy can perform many useful functions. This unit has been engineered and manufactured to assure your personal safety. Improper use can result in potential electrical shock or fire hazards. In order not to defeat the safeguards, observe the following instructions for its installation, use and servicing.

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION: To reduce the risk of electric shock, do not remove the cover. No user-serviceable parts inside. Refer servicing to qualified service personnel.

WARNING: To prevent fire or electric shock, do not expose this equip- ment to rain or moisture.

1- Maximum operating ambient temperature is 50°C (122°F).

2- Never restrict airflow through the device fan or vents.

Please insure that the air intake and exhaust vents are unob-

structed.

3- When installing equipment into rack, distribute the units evenly. Otherwise, hazardous conditions could be created by an uneven weight distribution.

4- Connect the unit only to a properly rated supply circuit.

The CM16a is suitable for connection to 100 - 240 VAC, 47 - 440 hertz, with no special considerations other than the appropriate IEC power cord.

5- Reliable Earthing (Grounding) of rack-mounted equip-

ment should be maintained.
