Installation
The Bulletin 1402 Line Synchronization Module (LSM) should be installed
in a Bulletin 1771 I/O chassis that is located in a dry, dirt free environment
away from heat sources and very high electric or magnetic fields. The
module is designed to operate in an ambient temperature between 0 and 60
°
Celsius. The LSM is typically installed in a local rack in order to maximize
data transfer rates.
This equipment is classified as open equipment and must be installed
(mounted in an enclosure during operation as a means of providing safety
protection. The enclosure chosen should protect the LSM from atmospheric
contaminants such as oil, moisture, dust, corrosive vapors, or other harmful
airborne substances. A steel enclosure is recommended to guard against EMI
(Electromagnetic Interference) & RFI (Radio Frequency Interference).
The enclosure should be mounted in a position that allows the doors to open
fully. This will allow easy access to the wiring of the LSM and related
components so that servicing is convenient.
When choosing the enclosure size, extra space should be allowed for
associated application equipment such as, transformers, fusing, disconnect
switch, master control relay, and terminal strips.
The LSM mounts in two slots of a Bulletin 1771 Series B, I/O chassis.
Mounting dimensions will vary with the size of the chassis selected. Refer to
the appropriate 1771 literature for specific dimensions.
The LSM backplane power requirement is 1.1A at 5V DC. Refer to the
appropriate 1771 literature for additional information on available power
supply current.
For correct and reliable performance, the grounding recommendations
specified for Allen–Bradley PLC

systems must be followed.
