2.6 INSTALLATION
2.6.1 BENCH TOP USE
If the unit is to be used as a bench top instrument, a bail located on the bottom of the unit can be
utilized to raise the front of the unit about two inches for ease of accessing the front panel con-
trols, indicators, keypad, and LCD display.
2.6.2 RACK MOUNTING
If the unit is to be rack-mounted, refer to Figure 1-2 for instructions.
2.6.3 “G” OPTION SELECTOR (MG AND MGR MODELS)
If the unit is to be incorporated into a remote-controlled power system (Figure 1-3), certain con-
siderations have to met:
• The Power System can only have one controller; therefor only one MBT Power Supply in
the system can have the “G” option enabled. To disable the “G” option on additional MBT
units in the Power System, set the “G” option ON/OFF selector switch accessed through
the top cover (Figure 2-2) to OFF. For “G” option models without this switch, contact
Kepco Inc. or a local representative for assistance. If controller other than an MBT “G”
option unit is used, disable the “G” option of all MBT units.
• Control of any MBT Power Supply in the system is possible from any MBT unit's keypad
in the “daisy chain” configured Power System.
• A remotely controlled Power System can have as many as 27 units. Each power supply
in the system must have a unique node address (see PAR. 2.5.1).
2.7 WIRING INSTRUCTIONS
Interconnections between an a-c power source and a power supply, and between the power
supply and its load are as critical as the interface between other types of electronic equipment.
If optimum performance is expected, certain rules for the interconnection of source, power sup-
ply and load must be observed by the user. These rules are described in detail in the following
paragraphs.
2.7.1 SAFETY GROUNDING
Local, national and international safety rules dictate the grounding of the metal cover and case
of any instrument connected to the a-c power source, when such grounding is an intrinsic part of
the safety aspect of the instrument. The ground terminal of the source power connector (figure
2-4) is connected the the MBT chassis and the instructions below suggest wiring methods which
comply with these safety requirements; however, in the event that the specific installation for the
power system is different from the recommended wiring, it is the customer's responsibility to
ensure that all applicable electric codes for safety grounding requirements are met.
2.7.2 SOURCE POWER CONNECTIONS
Source power is connected to the power supply via the three-wire power input cable supplied.
