Misplug

A guard lamp is installed on each trunk in the end position at the tandem board so that, if an "A" operator misplugs, the call may be answered promptly by the supervisor at the tandem board and cared for properly.

Be very careful not to misplug a three-wire system to the stage box and run 240V accidentally.

Cabling is labeled on both sides, so you won't misplug a device connector.

This circuit is so arranged that in case an operator at the manual end makes a misplug, the correction of the error will have no effect on the setting of the automatic.

With the integrated technology, it is easy to provide for the measures for linearization and temperature stabilization of the parameters and characteristics, overload and misplug protection, operation in a wide range of supply voltages, etc.

Do not use any other ports in the BPH. Any deviations or misplugs will affect the operation of the zEC12 system.

Where AC and DC sockets or sockets of different voltages are installed in the same place, they shall be distinguished clearly. And the sockets must be different in structure and specification and can't be exchanged to avoid misplug.
