Power Requirements
Class I Power Cords (3-core)
General
To connect the Test Set to a Class II (ungrounded) 2-terminal socket outlet, fit the power cord
with either a 3-pin Class I plug used in conjunction with an adapter incorporating a ground wire,
or fit the power cord with a Class II plug containing an integral ground wire. The ground wire
must be securely fastened to ground; grounding one terminal on a 2-terminal socket does not
provide adequate protection.
A 3-wire (grounded) power cord containing a molded IEC 320 connector is included with the
3900. The cable must be fitted with an approved plug which, when plugged into an appropriate
3-terminal socket outlet, grounds the case of the Test Set.
Failure to ground the Test Set or using a damaged power cord may expose the operator to
hazardous voltage levels. Replacement power cords are available from Aeroflex.
