b) VERTICAL UNITS
The B30 Bus Differential System is available as a reduced size (¾) vertical mount unit, with a removable faceplate. The
faceplate can be specified as either standard or enhanced at the time of ordering. The enhanced faceplate contains addi-
tional user-programmable pushbuttons and LED indicators.
The modular design allows the relay to be easily upgraded or repaired by a qualified service person. The faceplate is
hinged to allow easy access to the removable modules, and is itself removable to allow mounting on doors with limited rear
depth. There is also a removable dust cover that fits over the faceplate, which must be removed when attempting to access
the keypad or RS232 communications port.
The case dimensions are shown below, along with panel cutout details for panel mounting. When planning the location of
your panel cutout, ensure that provision is made for the faceplate to swing open without interference to or from adjacent
equipment.
