Dings Dynamics Group 60 Series End Mount NEMA 2 - Manual (Page 2)

WARNING:
Brake performance and features must be carefully
matched to the requirements of the application.
Consideration must be given to torque requirements,
especially where an overhauling condition exists, as
well as thermal capacity, ambient temperature,
atmospheric explosion hazards, type of enclosure and
any other unusual conditions.
Improper selection and installation of a brake and/or
lack of maintenance may cause brake failure which
could result in damage to property and/or injury to
personnel.
If injury to personnel could be caused by brake failure,
additional means must be provided to insure safety of
personnel.
UNPACKING
When unpacking the brake, inspect it carefully for damage
that may have occurred during transit.
GENERAL SAFETY INFORMATION
NOTE: These brakes are not intended for accurate
positioning applications. They are designed for applications
that require rapid stopping and holding power, such as on
conveyors, door openers, etc.
1. For applications with high inertia-type loads or rapid
cycling, the thermal capacity of the brake must be
considered.
2. Observe all local electrical and safety codes, as well
as the National Electrical Code (NEC) and the
Occupational Safety and Health Act (OSHA).
3. Brake motors and brake gearmotors must be
securely and adequately grounded. This can be
accomplished by wiring with a grounded metal-clad
raceway system, by using a separate ground wire
connected to the bare metal of the motor frame, or
other suitable means. Refer to NEC Article 250
(Grounding) for additional information. All wiring
should be done by a qualified electrician.
4. Always disconnect power before working on or near
a brake motor, a brake gearmotor, or its connected
load. If the power disconnect point is out of sight,
lock it in the open position and tag it to prevent
unexpected application of power.
5. When working on the brake, be sure the load is
completely removed, secured or blocked to prevent
injury or property damage.
6. Provide guarding for all moving parts.
7. Be careful when touching the exterior of an operating
motor, gearmotor or brake. It may be hot enough
to cause injury or to be painful. This condition is
normal for modern motors, which operate at higher
temperatures when running at rated load and
voltage.
8. Protect all electrical lead wires and power cables
against contact with sharp objects or moving parts.
9. Do not kink electrical lead wires and power cables,
and never allow them to touch oil, grease, hot
surfaces, or chemicals.
INSTALLATION
CAUTION: To preserve pre-alignment of rotating discs
for ease of installation, do not operate manual release or
energize brake coil before installation.
NOTE: The brakes are designed for horizontal mounting.
Modification is required for vertical mounting. Brakes that are
modified will have a prefix on the model number of VO
(Vertical Over) or VU (Vertical Under).
Numbers in parentheses refer to parts illustrated in Figs. 3,
5, 6 and 9.
Mounting Hub on Motor Shaft
1. Remove hub (1) from brake and position it on motor
shaft with key as shown in Fig. 1. Stamped part
number on hub should face away from motor.
Tighten hub setscrews with 8 to 10 lb. ft. torque.
Placing Brake on Motor Shaft
1. Remove two cover locknuts (22) and cover (20).
Position brake over hub on shaft, aligning hub
splines with rotating disc splines.
2. Bolt brake to motor flange with four 3/8 - 16 socket
head capscrews.
NOTE: Dimension “G” (Fig. 1) is the length of the
mounting hole through brake bracket.
3. Place coil lead wires around mounting bracket (15C)
to the same side as the desired wire outlet position.
Connect lead wires per “Connection of Coil Leads”
and Fig. 2.
4. Replace cover (20) and cover locknuts (22). Tighten
just enough to hold the cover in place.
