RACK MOUNTING
Using a Kepco RA 24 Rack Adapter, two 1/2 rack BHK-MG 40W units can be mounted in a 19-
inch wide rack, after the bench-type feet are removed (see Figure 1-3). Optional slides for the
rack adapter (see Table 1-5) can be used to improve access to the unit.

WIRING INSTRUCTIONS
Interconnections between an a-c power source and the 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.
To access to the output and analog programming terminal strips it is necessary to pull out the
terminal drawer as follows:
1.
Loosen two captive screws securing the terminal drawer to the rear panel.
2.
Use the handle provided to pull out the terminal drawer.
3.
Remove two screws attaching the protective insulator to the terminal strip PC board, then
snap out the insulator and remove it.
4.
Thread wires through wire-entry bushing before connecting to terminal strip.
5.
After all connections have been completed, snap the insulator in place and secure with two
screws. Then insert the terminal drawer into the rear panel (taking care that the bottom of
the PC board/insulator engage the internal guides) and secure with two captive screws.
NOTE: The unit will not operate unless the terminal drawer is securely inserted in the rear
panel.
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
2-2) is connected to the BHK-MG 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 input power cable supplied.
2.7.3
D-C OUTPUT GROUNDING
Connections between the power supply and the load and sensing connections may, despite pre-
cautions such as shielding, twisting of wire pairs, etc., be influenced by radiated noise, or “pick-
up”. To minimize the effects of this radiated noise the user should consider grounding one side
of the power supply/load circuit. The success of d-c grounding requires careful analysis of each
specific application, however, and this recommendation can only serve as a general guideline.
