FUSE - A component in an electrical circuit that will open the circuit if too much current flows
through it.
REED SWITCH - A switch whose contacts are controlled by a magnet. A magnet closes the
contacts of a normally open reed switch; it opens the contacts of a normally closed reed switch.
SENDER - A component that is used with a temperature or pressure gauge. The sender
measures the temperature or pressure. Its resistance changes to give an indication to the
gauge of the temperature or pressure.
RELAY (Magnetic Switch) - A relay is an electrical component that is activated by electricity.
It has a coil that makes an electromagnet when current flows through it. The electromagnet
can open or close the switch part of the relay.
CIRCUIT BREAKER (C/B) - A component in an electrical circuit that will open the circuit if too
much current flows through it. This does not destroy the circuit breaker and it can be reset to
become part of the circuit again.
SOLENOID - A solenoid is an electrical component that is activated by electricity. It has a coil
that makes an electromagnet when current flows through it. The electromagnet can open or
close a valve or move a piece of metal that can do work.

Normally open switch that will close with an increase of a specific condition (temp-press-etc.).
Normally open switch that is closed due to an applied condition, and will open again with a
specific decrease in that condition.
Normally closed switch that will open with an increase of a specific condition.
Normally closed switch that is open due to an applied condition, and will close again
with a specific decrease in that condition.
The circle indicates that the component has screw terminals and a wire can be disconnected
from it.
No circle indicates that the wire cannot be disconnected from the component.
This indicates that the component has a wire connected to it that is connected to ground.
This indicates that the component does not have a wire connected to ground. It is grounded
by being fastened to the machine.

1 WITH A BALANCED THREE PHASE LOAD AND UNITY POWER
FACTOR, THE CURRENT TRANSFORMERS SHOULD BE WIRED
IN THE CORRECT POTENTIAL LEG AND MUST BE PHASED AT
THE CONTROL AS FOLLOWS:
PHASE A: POTENTIAL TERMINAL 1, WITH RESPECT TO
NUETRAL, IN PHASE WITH CT TERMINALS 4 TO 5.
PHASE B: POTENTIAL TERMINAL 2, WITH RESPECT TO
NEUTRAL, IN PHASE WITH CT TERMINALS 6 TO 7.
NEUTRAL, IN PHASE WITH CT TERMINALS 8 TO 9.
PHASE C: POTENTIAL TERMINAL3, WITH RESPECT TO
2 POWER SOURCE CURRENT TRANSFORMER SHOULD BE SIZED
TO PRODUCE 5A SECONDARY CURRENT WITH MAXIMUM
GENERATOR CURRENT. CT BURDEN IS 0.1 VA
CONTACTS TO CLOSE WHEN BREAKER CLOSES.3
4 THE GENERATOR CURRENT TRANSFORMERS MUST BE
CONNECTED TO THE APPROPRIATE TERMINALS OF THE
LOAD SHARE MODULE WHENEVER UNIT IS RUNNING TO
PREVENT LETHAL HIGH VOLTAGE FROM DEVELOPING ON
LEADS TO THESE TERMINALS.
5 POTENTIAL TRANSFORMER BURDEN IS 5VA PER PHASE
WITH 230VAC INPUT AND 2.5 VAC PER PHASE WITH
115 VAC INPUT.
SIGNAL LINES SHOULD BE TWISTED SHIELDED WIRES.6
REGULATIONS. GROUND WIRE MUST BE AT LEAST AS LARGE
PROTECTIVE EARTH GROUND, USE AS REQUIRED BY
AS THE WIRES ON TERMINALS 1 THROUGH 9.
7
THE NEAREST CHASSIS SCREW .
CONNECT THE SYNCHRONIZER AND SPEED TRIM SHIELDS TO 8
OF 65mm OR GREATER TO COMPLY WITH EUROPEAN
INSULATED SLEEVES AND MUST HAVE A CREEPAGE DISTANCE
THE WIRE LUGS ON TERMINALS 3 AND 4 MUST HAVE 9
UNIONS LOW VOLTAGE DIRECTIVE.
