Installation Planning Guidelines
This section provides the additional information necessary for planning the installation of the
RCK1000 system .
Grounding
Failure to provide proper grounding to each system unit (RM125/RM125R, 1KW PA and PS unit,
and to the optional PPS) and to the rack in which these units are installed 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 common grounding point within the rack, which is connected to a
reliable, low-resistance grounding system.
Power Requirements
The RCK1000 PS unit requires AC power at a nominal voltage of 110 or 220 VAC, 50/60 Hz. The
PS unit will automatically select the appropriate voltage range.
The maximum AC power consumption during high-power transmission is up to 5 kW.
In addition to the circuit breaker or fuse protecting the supply line to the RM125/RM125R, a
suitably rated circuit breaker or fuse must be used to protect the supply line of the PS unit, and
enable disconnection of its supply voltage during installation and maintenance.
Cooling
RCK1000 units are cooled by internal fans. Air is taken in through the front panel vents, and
discharged toward the rear. Therefore, make sure that sufficient free space is available around
the equipment to enable free air flow.
Do not stack equipment units: leave at least 1U free above and below each unit installed in the
rack.
Installation Data
The RM125/RM125R, the optional Pre-Selector/Post-Selector (PPS) , the 1kW PA and the power
supply , are intended for installation in the provided 19” rack. The interface cable kit for MICOM
1KW linear amplifier, option G156, is also intended for installation in the same rack.
Each equipment unit has front-mounted brackets for attachment. To provide convenient access
during maintenance, each equipment unit is installed on slides capable of supporting the
equipment weight.
The rack itself must be securely fastened to the floor, before starting the installation activities.
Sufficient front and rear clearance is required to permit convenient access to front and rear
