1. IMPORTANT SAFETY INFORMATION

WARNING.

Any person performing the procedures described in this manual will be exposed to hazardous voltages and the risk of
electric shock.

Carver Corporation assumes that any person who removes the cover from the unit has been properly trained in protecting
against avoidable injury and shock.

Therefore, the procedures described here are to be performed by qualified electronics service personnel only.

We recommend that the unit be tested only when line isolation is provided by an isolation transformer. The line cord of
the unit must be disconnected and the power supply capacitors fully discharged before any components are replaced.
Failure to do so may result in severe damage to the unit and the risk of electric shock.

CAUTION:

Before returning the unit to the customer, one of the following safety tests must be performed.

1. Check the leakage current. Connect the unit to 120 VAC supply and turn the power switch ON. Using an ammeter,
measure the current between each side of the linecord and chassis ground of the unit under test. If leakage current
exceeds 0.5mA, the unit is defective.

2. Measure the resistance from either side of the linecord to chassis ground. If it is less than 500k ohms, the unit is
defective.

WARNING: DO NOT return the unit to the customer if it fails one of these tests until the problem is located and
corrected.
