Assembly is easier with front-entry wiring and Cage Clamp connection for 12 to 28-awg conductors guarantee vibrationproof connection. A key feature for the block is a jumper system for the power supply. Jumper slots are very small and accommodate a new noninsulated push-in jumper bar that is protected against accidental contact. Jumpers come in 2 through 17-way versions for power distribution. On the signal level, the jumper positions are compatible with Series 870 rail-mounted terminal blocks using Cage Clamp Compact connection. An LED for status indication and three locations for marker cards per terminal block are available. Color-coded connections make field wiring easier.
