Caution: Connecting the equipment to the wrong circuit may cause damage to the equipment or the fuse platform. Make sure the fuse is the correct type and has the correct current rating as specified by the equipment manufacturer.
Note: The continuous output load of the equipment during normal operation should not exceed 80% of the rated value of the fuse. This allows some room for manufacturing tolerances and voltage fluctuations in the plant power mains.
4.6Connecting Input Power
Input power is supplied to the fuse platform through the single or dual terminal blocks located on the rear of the platform. Each input terminal block consists of two pairs of
The stud pairs are mounted on 0.625 inch centers and accept
Warning: Use of one bus only on a dual bus panel will result in false alarms for the unused bus. Power is required on both buses on a dual bus panel for normal operation.
Caution: Connect only the input voltage wire [the wire labeled BATTERY or BATT, or labeled with the negative
Caution: Caution should be taken to not reverse the input wires to the fuse platform. Within the panel, the internal return wiring is not protected by fuses. If the wires are reversed, current will flow through the unprotected return wiring in the panel to the equipment. This condition can cause damage to the equipment in the frame in which the panel is installed and to equipment in adjacent frames
Use the following procedure to connect the input power cables to the fuse platform:
1.Obtain eight lengths of #2 AWG wire for use as the input power cables.
2.Strip back 7/8 inches of insulation from one end of each wire as shown in Figure 18.
