Fuses

The MCCB is provided with two fast 15A fuses (see Fig. 17–1 and Fig. 17–3) to protect the external power supply from short circuit. Only use the following fuses: 7006100123, 250/15A.

DTU Cable Ground Strap Settings

The straps on the MCCB connect the cable shield of the PBX/MCCB coax cables to ground. The MCCB is delivered with all straps in the ground position (see Fig. 17–2). This setting gives the best EMC protection.
