4.9Installing Fuse Designation Card Holder and Card

Attach the fuse designation card holder to the fuse platform, to one of the fuse platform mounting brackets, or to a part of the rack. Remove the backing from the back of the card holder and press the card holder against the mounting surface. Fill out one of the cards with the required circuit information insert it in the card holder.

4.10 Installing Voltage Designation Label

Write the voltage used in the fuse platform on the voltage designation label and attach the label to the back of the fuse platform.

4.11 Installing Fuses

Replace the dummy fuses in the fuse holder with the appropriate type and value fuses. Leave the dummy fuses in unused fuse positions.

5 SYSTEM CHECK

Perform the following procedures to check out the platform after completing installation.

5.1Wiring Connections Torque Measurements

Measure the torque of all input, output, chassis ground and fuse alarm relay contact connections included in the non-powered testing paragraphs above using a torque screwdriver that is calibrated in pound force-inches (Newton-meters). The torque specifications are printed on the rear of the panel adjacent to the connector.

5.2Power Indication Test

After checking input resistance and verifying the wiring connections torque, power may be applied to the fuse platform. Upon power application, the fuse alarm indicators will not light unless no fuse is in the fuse holder or a fuse that has failed is in the fuse holder.

Note: The KLM fuse positions require that a load be connected to the corresponding outputs in order for the indicators to light.

The fuse alarm relay should indicate an open circuit between the normally open (NO) terminals and the common (C) terminals and a closed circuit between the normally closed (NC) terminals and the common terminals.
