RM125/RM125R Installation
Warning
For general operating and installation safety information, see the
“Owner’s Guide, MICOM-3E/3T/3R HF-SSB Transceivers”, Publication
6886867J01.
During installation work, strictly observe the applicable safety precautions
and local regulations. Do not work on the antenna system during
lightning storms.
Warning
Proper grounding is essential for your safety, and for good
communication performance.
Do not touch the antenna and the RF connectors while the radio set
operates. During transmission, high RF voltages appear at the RF
connectors, the antenna cables, and on the antenna itself. These voltages
may cause severe injury or death on contact.
Make sure the antenna is not located near high-voltage lines.
All personnel must be familiar with the applicable safety requirements
before attempting to install or operate the radio set. Severe injury or
death could result from failure to comply with the safety practices.
Installation Planning Guidelines
This section provides information necessary for planning the installation of RM125/RM125R.
Grounding
Failure to provide proper grounding will degrade system operation and cause RF voltage to be present
on the equipment chassis. A possible serious hazard to personnel could result, as well as equipment
malfunction.
Wide copper straps, as short as possible, must be used for grounding. These straps must be clamped
or bonded to a reliable, low-resistance grounding system.
AC Power Requirements
The RM125/RM125R requires AC power at a nominal voltage of 110 or 220 VAC, 50/60 Hz. The
RM125/RM125R will automatically select the appropriate voltage range.
The maximum AC power consumption during high-power transmission (excluding the charging of an
external battery), is 500W.
A suitably rated circuit breaker or fuse must be used to protect the supply line to the
RM125/RM125R, and enable disconnection of supply voltage during installation and maintenance.
DC Power Requirements
The RM125/RM125R can also operate from an external 13.8 VDC source, connected to its BAT
terminals. Two types of DC sources may be used:
