EX, SGX VIBRATOR MOTORS
Connections to Motor
The procedure below describes motor cord connections to the motor. If replacing a cable, tag all
leads for identification before disconnecting old cable. The EX and SGX motors use either the
following connection styles:
Terminal Block
- Cord is fed through the side of the motor junction box and connected to a
terminal block inside the junction box
Power Connector
- Cord is fed through the junction box cover, which contains a female power
connector where connections are made. This connector plugs into a male plug in the junction box.
Terminal Block Style
1. Remove cover from motor junction box.
2. Carefully feed the wires through the elbow installed in the motor junction box (Figure 2).
3. Install and tighten gland assembly components in elbow, using care to avoid over-tightening
backnut. To prevent over-tightening, stop tightening backnut when red seal begins to swell.
4. Install two O-rings over leads inside junction box, slide both O-rings into threaded hole in box,
and position one O-ring at each end of threaded hole to suspend the leads in the center of the
hole.
Note! Be sure that O-rings are properly installed, as they prevent chafing of
leads due to abrasion against threaded hole.
5. Route leads as shown, dressing carefully to prevent leads from contacting each other or the
interior of the connection box.
6. Secure black, white, red, orange, and blue leads to studs as marked on terminal block using
external tooth lockwashers and Flex-Loc
®
nuts. Secure green lead to GROUND terminal using
lockwasher and screw.
7. Apply RTV-108-10.1 silicone sealant to leads (Figure 3) for vibration-proofing. Also, be sure to
fill threaded hole for additional protection against chafing.
8. Place cover on motor junction box, and install and tighten four screws to 250 in-lbs.
