2.5 PRELIMINARY CHECK-OUT
2.5.1 REQUIRED EQUIPMENT
• Host computer w/communication cable for selected controller
• Kepco Controller (See PAR. 1.4.1).
• RA 55 or CA 400 rack adapter; alternative is to use Input Power/Communication Cable
(see Table 1-3)
• Load Interface Cable or mating load connector (see Table 1-3)
• Digital Voltmeter (DVM)
• Switch (SPST) rated 32V d-c, 1A
2.5.2 INITIAL SETUP
Initial set-up is as follows (See Figure 2-3):
1. Connect the Unit under test (UUT) to the computer/controller interface (refer to the appropri-
ate Controller Instruction Manual and to the Rack Adapter (RA 55 or CA 400) Instruction
Manual for source power connections). NOTE: An Alternative configuration using the Input
Power Communication cable in place of the rack adapter may be used.
2. Install the MST Power Module into a vacant rack adapter slot (see PAR. 2.6.2).
3. Configure the Load Interface Cable as shown in Figure 2-2. If the Load Interface Cable is not
available, wire load mating connector as shown in Figure 2-2.
