Safety and Regulatory Information
Site Preparation
Site Preparation
Install the instrument so that the detachable power cord is readily identifiable
and is easily reached by the operator. An externally installed switch or circuit
breaker (which is readily identifiable and is easily reached by the operator)
should be used as the disconnecting device.The detachable power cord can
also be used to disconnect the mains circuits from the mains supply before
other parts of the instrument. The front panel switch is only a standby switch
and is not a LINE switch.
Power Requirements
Before installing the system, be sure that the required ac power is available at
all necessary locations.
— Three-wire power cables (which provide a safety ground) must be used with
all instruments.
— Air-conditioning equipment (or other motor-operated equipment) should
not be placed on the same ac line that powers the system.
— The table below lists the maximum VA ratings and BTU/hour ratings for all
instruments in the system. This table can be used to determine both the
electrical requirements and the air conditioning requirements of the system
.
