1–1 Description

The TVRMS2 Digital Test Kit is a light-weight, portable

test instrument designed for field testing of RMS-9, Epic,

Power+™, MicroVersaTrip Plus™, and MicroVersaTrip

PM™ Trip Units. The Test Kit includes the following

features:

• Operation from 120 Vac or six D-cell batteries.

• Trip Unit testing without de-energizing the breaker

or removing the Trip Unit from the breaker.

• Verification of switch settings on Power+, RMS-9 and

Epic Trip Units.

• Either trip or no-trip testing for time-overcurrent

characteristics.

• Monitoring of pickup current and trip time during

high-current injection testing.

• Menu-driven test procedures for ease of use.

The Test Kit interface with the Trip Unit is a three-wire

digital communication link through the test jack on the

front of the Trip Unit, as illustrated in Figure 1.
