3.2.2 Vertical units
The B30 is available as a reduced size (¾) vertical mount unit, with a removable front panel. The front panel is specified as
enhanced or standard at the time of ordering. The enhanced front panel contains additional user-programmable
pushbuttons and LED indicators.
The modular design allows the relay to be upgraded and repaired by qualified service personnel. The front panel is hinged
to allow easy access to the modules. The front panel is itself removable to allow mounting on doors with limited rear depth
and for upgrading.
The case dimensions are shown in the following figures, along with panel cutout details for panel mounting. When
planning the location of your panel cutout, ensure that provision is made for the front panel to swing open without
interference to or from adjacent equipment.
The relay must be mounted such that the front panel sits semi-flush with the panel or switchgear door, allowing the
operator access to the keypad and the RS232 communications port.
