4.8Installing GMT Fuse Designation Pins

Color-coded fuse designation pins (accessory item) are available for GMT fuses. The pin color corresponds to the color of the fuse indicator. Insert the appropriate color-coded pins (accessory item) into the corresponding holes in each GMT fuse holder as required.

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.

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 On and Connection Polarity Test

Use the following procedure to apply power to the fuse platform and verify that the power input wires are connected correctly:

Note: This procedure assumes that no fuses have been installed yet.

1.Verify that the input power cables are connected to the correct terminals.

2.Verify that the circuit breakers for all circuits are on.

3.Apply power to the unit.

4.Verify that the power-on indicator (green LED) for each power bus in lit. (The fuse platform being installed may have either one or two power buses.)

5.Verify that no fuse alarm LEDs on the front of the fuse platform are red or green.
