Panel Installation
CANdrive modules are surface-mounted with 4 x no.4 screws, fixing centre dimensions as
shown. Select screw length according to panel thickness, ensuring a maximum of 13mm
(½ inch) screw depth into the CANdrive fixing holes.
Model CDV100F, with forward facing connector, is designed for surface mounting inside
an enclosed panel. Model CDV300F, with 8 LED indicators and rearward facing connector,
is designed for front-of-panel mounting: this module requires an additional 60 x 40mm
(2.4 x 1.6 in.) panel cut-out for rear access to connector and switches. A CDV300F with
optional gasket CDVG (fitted into a well behind the case rim) provides IP65 front-of-panel
environmental sealing.
Before installing, ensure that the final mounting location meets operating temperature and
environmental sealing requirements, and allows access for:
a) connection of the wiring harness
b)
configuration of DIP switches S1 to S5 (location as shown above right). Alternatively,
set these switches before panel fixing – see Configuration section below for full details.

Configuration
DIP switches S1 to S5 allow OEM- or user-configuration of
CANdrive operating options. Switch S6 is not used. CANdrive
is supplied with all switches in the ON (up) position.
Switch settings must be made as appropriate, according to
the configuration table right. Adjustment of the switch
positions must be made while CANdrive is powered down.
