INSTALLATION. Install units in a 19 inch-wide rack. Optional slides may be used. Leave the front
and rear panels clear of obstructions to ensure adequate cooling. For parallel, series and master-slave
configurations, refer to the User Manual.
INPUT CONNECTIONS. Operation at rated load power (2400W) over the full rated source voltage range (180
- 265V a-c) requires a branch service rating of 20 Amperes; Kepco recommends use of #12 AWG (2,0 mm 2 ) for pri-
mary wiring. For operation at output power of 2000W or less, or with source voltage not less than 200V a-c, branch
service may be reduced to 15 Amperes using #14 AWG (1,6 mm
2
) wiring. Line cords and a user-wireable
source power connector are available as accessories (see Table 3). Plug the (wired) source power con-
nector or line cord into the source power inlet connector at the rear panel.
LOAD CONNECTIONS. Connect the load to the (+) and (–) DC OUTPUT terminals on the rear panel
(Figure 2). (+M) and (–M) outputs are for local connection of error sense leads.
Configuration of local sensing is facilitated by pre-installed jumpers which configure the unit for local
sensing as shown in Figure 2.
NOTE: Output Sense lines must be connected for proper operation, either locally, or at the load
(remote).
