Compact Amplifier Type 93421 Installation Instructions
Application
The Compact Amplifier type 93421 has two active outputs and is used in trunk and
distribution applications. The amplifiers can be monitored via the Compact
Transponder and TNCS. The housing is suitable for outdoor mounting.
Mounting
The node is mounted perpendicularly with the cable inlet at the bottom in order to
secure natural ventilation during operation. To ensure a proper seal, tighten the bolts
in sequence as shown in the section titled Mounting Sequence. Use a 13 mm wrench
for the screw in the lid and torque to 7 Nm.
