MobileAccessGX Installation and Configuration Guide 45
When using the MobileAccess system in an environment in which other indoor coverage
systems are installed, it is recommended (where possible) that the antennas are placed
at least two meters apart
When bending coax cables, verify that the bending radius does not exceed the coax
specifications.
Use wideband antennas supporting a range of 800Mhz to 2500Mhz
Use a VSWR meter (i.e. Site Master or equivalent) for checking coax cables, including
the antennas. (<2). The VSWR must be measured prior to terminating the RUs in the
remote communication rooms
Terminate all unused RU and RIU ports with a 50 ohm load

Power Safety Instructions
SAFETY WARNINGS
When installing or selecting the power supplies:
Be sure to disconnect all power sources before servicing.
SC-450 Controller lithium type battery should only be replaced by MobileAccess service
personnel. Risk of exploding if battery is replaced by an incorrect type. Dispose
of used batteries according to the instructions.
Calculate the required power according to the requirements of the specific installation
and then determine the configuration of the power supplies. The required DC cables will
then be determined by the selected PS configuration.
Use only UL approved power supplies
AC and DC power supply cables – only use the power cords supplied with the units
Battery replacement in units - only the SC-450 controller has batteries. These should
be replaced (when necessary) only by MA Service Personnel.
Install external over-current protective devices for the system according to the
requirements.
