Do not operate manual release or energize brake coil before

installation in order to preserve pre-alignment of rotating

disc for easy installation of brake to motor.

Because of the close fit on all joints (bracket, cover, hub),

care should be taken to prevent damage to all machined

surfaces.

Do not operate brake in hazardous location with cover

removed. All testing must be done in a non-explosive

atmosphere.

1. Remove hub (6) from brake and mount hub with key

(not supplied by Dings) on motor shaft per dimension

shown in Figure 5. Be sure that hub used is item

supplied by Dings for hazardous location applications.

Tighten both set screws to 8-10 lb. ft. torque.

2. Cast Iron Enclosure: Remove four cover bolts (42A)

and lockwashers (43) and remove cover (38A).

Cast Aluminum Enclosure: Remove four cover bolts

(42B), flat washer (9), locknut (8) and cover (38B).

3. Inspect motor "C" flange and remove any nicks or

burrs. This will assure a precision fit of brake to motor

flange. Slide brake over hub (6), engaging teeth of

rotating disc (2) and hub.

4. Install four mounting bolts (10) and tighten to 40 lb. ft.

torque. Install four locking set screws (11) and tighten

to 40 lb. ft. torque. This seals flame path around

mounting bolts. Check rotation of hub to make certain

it does not rub in bracket (5). Diametrical clearance of

hub outside diameter to bracket bore shall not exceed

.024".

5. Connect brake coil leads to any two line leads of same

voltage as brake. All wiring should be positioned to

prevent pinching or chafing and all connections well

taped to prevent grounding.

6. Replace cover (38A or 38B). Make certain that two

pins of release shaft (35) fit over roll pin (32). A soft

mallet may be used to tap cover in place. Fasten

with four bolts (42A or 42B), washers (9 or 43) and

locknuts (8). A loose or missing bolt will render the

brake unsafe for operation in hazardous locations.

7. Inspect motor "C" flange and remove any nicks or

burrs. This will insure a precision fit of adapter to the

motor flange. Mount adapter to motor flange using the

four bolts and lockwashers supplied. A soft mallet may

be used to tap adapter into place. All bolts should be

drawn up evenly and tight.

Check alignment of adapter. Clamp dial indicator to

brake hub (position A) and measure pilot eccentricity.

This must not exceed .002" total indicator reading for

a full revolution of hub. Reposition dial indicator

(position B) and check adapter face runout which

must not exceed .004" total indicator reading for a full

revolution of the hub. Remove hub (6) from brake and

mount hub with key (not supplied by Dings) on motor

shaft per dimension shown in Figure 3. Tighten both

setscrews to 8-10 lb. ft. torque. Complete mounting of

brake per paragraphs 2 through 6.
