ARTS
There are seven replacement or accessory kits that are available for the HRE-454 enclosures.
lists these kits. Following are the topics regarding replacement parts:
•
Replacing the Stainless Steel Dome Cover
•
Replacing LPU Arrestor Boards
The HRE-454 contains replaceable LPU surge arrestors. (See
“Replacing LPU Arrestor Boards” on page 58
instructions on replacing the LPU surge arrestors.) Additionally, ADC recommends that the O-ring be closely
examined whenever the housing is opened for maintenance. Be sure to replace the O-ring if it becomes damaged.
The screen divider is an insulated floating divider that isolates Group 1 (blue thread, side 1 in)
and Group 2 (green thread, side 2 in) from Group 3 (orange thread, side 1 out) and Group 4
(brown thread, side 2 out) in the cable stub.
Do not ground the divider or connect it to the screen divider of the main cable. This may result
in poor performance. The aluminum tape used to wrap the input and output pairs provides the
necessary isolation.
Kits 132-1010, -1011, -1013, -1014; 132-1038-01; and 132-1030-01 are available for damaged
components. Kit 132-1916-01 contains a typical set of nuts and bolts mounting hardware.
