Description

3RE4 non-combination motor controllers include a

horsepower rated contactor and an overload relay

(OLR) with a reset operator (for motor starters).

They may also include optional factory installed

accessories such as pilot devices and a control

power transformer.

The NEMA Type 1 enclosures have a lift-off cover.

They are suited for general purpose indoor applica-

tions only.

The NEMA Type 3/3R/4/12 enclosures have a

removable hinged door. They are water and dust

tight and are suited for outdoor as well as indoor

applications.

The NEMA Type 4X 304 stainless steel enclosures

are noncorrosive and have a removable hinged

door. They are water and dust tight and are suited

for outdoor as well as indoor applications.

Pre-Installation

1. Examine the enclosure and each component for

shipping damage. Notify carrier for a claim if any

damage is found. DO NOT attempt to install or

apply power to any damaged product.

2. Verify that the horsepower, voltage and current

rating of the motor do not exceed the controller

rating.

3. If the control circuit is to be powered by an

external source, verify that the supply voltage

matches the voltage rating of the contactor coil.

4. If a control power transformer is supplied with

the controller, verify that the supply voltage

matches the primary voltage of the control

power transformer.

5. For controllers other than size S2 starters, skip

this step and proceed to the next one. Size S2

starters are shipped with the OLR uncoupled

from the contactor. This is to help prevent

damage should the product be mishandled

during shipment. The OLR must be coupled to

the contactor by following these steps:

a. Couple the OLR to the contactor as

shown in Figure 1.

b. A jumper wire should already be

connected to terminal A2 on the contactor.

Route the loose end of the wire between

the contactor and OLR as shown in

Figure 2.

c. Connect the loose end of the wire to

terminal 95 on the OLR.
