Mounting
!
ATTENTION: The ED Module and Allen–Bradley AC & DC Drives
all contain ESD (Electrostatic Discharge) sensitive parts and
assemblies. Static control precautions are required when installing,
testing, servicing or repairing this assembly. Component damage may
result if ESD control procedures are not followed. If you are not
familiar with static control procedures, reference A-B publication
8000-4.5.2, Guarding Against Electrostatic Damage or any other
applicable ESD protection handbook.
!
ATTENTION: Severe injury or death can result from electrical shock,
burn, or unintended actuation of controlled equipment. Hazardous
voltages may exist in the cabinet even with the circuit breaker in the off
position. Multiple sources of power may be connected to the Drive.
Recommended practice is to disconnect and lock out control equipment
from all power sources and discharge stored energy in capacitors, if
present. If it is necessary to work in the vicinity of energized
equipment, the safety related work practices of NFPA 70E, Electrical
Safety Requirements for Employee Workplaces, must be followed. DO
NOT work alone on energized equipment!
1. Remove all power to the Drive.
2. The Encoder Driver Module is supplied with a mounting bracket for
mounting in an appropriate enclosure outside the drive cabinet. It
should be located as close to the reference device (encoder etc.) as
possible. The module can be mounted in any orientation, but it must
be isolated from vibration, temperatures outside the range of 0
°
to
+40
°
C (32
°
to 104
°
F) and any contact with liquids, chemicals or
volatile gas/dust.
Connections 1. Terminal strip TB1 on the Encoder Driver Module is used for
incoming reference signal and power supply terminations as shown in
Figures 1 thru 3. Incoming signals from a reference
device could be connected are shown in these examples.
2. You must provide power in the range of 12VDC to 24VDC to the
Encoder Driver Board at TB1 Terminals 7 & 8. In 1395
applications, 12VDC can be obtained from terminals 13 & 14 of TB3
provided the total load is not greater than the capibility of the 12 volt
supply. If 24VDC input power is desired it must be provided from a
separate 24V power supply. The Encoder Driver Board has an internal
regulator that automatically compensates, allowing it to operate with
either power source. The module mounted heat sink will dissipate more
power with the 24 volt supply input.
3. The Encoder Driver Board output signals originate at TB2. Use the
examples in Figures 1 thru 3 as a reference when making output
connections.
