Chapter 2 Installation and Wiring
Control Circuits
The E300 relay can provide motor control logic for many different types of
motor starters (see Chapter 5
for more information on Operating Modes). By
default, the E300 relay is configured for the Overload-Network operating mode.
The following wiring diagrams are typical control circuits for Non-Reversing and
Reversing Motor starters that use the Overload-Network operating mode when
Relay 0 (terminals R03 and R04) is configured to be a normally closed Trip Relay.

ATTENTION: Do not exceed the ratings of the E300 relay’s output and trip relay.
If the coil current or voltage of the contactor exceeds the overload relay’s
ratings, an interposing relay must be used.
ATTENTION: When the power is applied to the E300 relay’s A1 and A2
terminals, the N.O. relay contact that is assigned as a Trip Relay closes after
approximately 2 seconds if no trip condition exists.
ATTENTION: More control circuit protection may be required. See the
applicable electrical codes.
