2.4 N7 Enclosure Installation
CAUTION
The X40-32-N7 controller can support up to a maximum of 32 sensors and any
associated I/O modules, but no I/O modules can be installed in the controller. All
I/O modules must be mounted separately by the customer. The N7 version does not
supply power to sensors. Power must be supplied by the customer for sensors and
any I/O modules. Damage to the controller may result if the maximum number of
sensors is exceeded.
1. Securely mount the X40-32-N7 controller in accordance with the mounting dimensions provided in
Figure 18.
