Installation
For proper installation and subsequent operation of the
LN-VAVCF-12 controller, follow these
recommendations:
Inspect the controller for shipping damage. Do not
install damaged devices.
Allow for proper clearance of device casing, wiring
terminals, and service pin for easy access,
hardware configuration, and maintenance.
The controllers are designed to operate under the
following conditions:
Ambient temperature between 32 to 122°F
(0 to 50°C)
Relative humidity from 0 to 90%,
noncondensing
Ensure proper ventilation of devices and avoid
areas where corroding, deteriorating, or explosive
vapors, fumes, or gasses may be present.
Record the Neuron® ID located on the box and on
the side of the controller. You need it for
commissioning the device.
IMPORTANT: Work in a static-free area. Discharge
any static electricity you may have accumulated.
Discharge static electricity by touching a known,
securely grounded object. Do not handle the
controller without proper protection against static
discharge. Use a wrist strap when handling the
controller. Secure the wrist strap clamp to earth
ground.
