Installation with panel mounting
As well as the actual instrument and these instructions
for use, the controller package also contains:
• 2 panel fixing brackets (A)
• 1 protective seal against dust and water spray (B)
Fit the instrument to the panel as shown in the figure.
Warnings and instructions for mounting to the panel
Instructions for installation category II,
pollution level 2, double isolation.
• only for models with 20...27Vac/dc power supply:
supply from Class 2 or low voltage limited energy
source
• the power supply lines must be separate from the
controller input and output ones
• group the instruments together keeping them separate
from the powered part of the relay
• do not install high-power remote switches, contactors,
relays, thyristor power units (especially the “phase
angle” type), motors, etc. in the same switchboard
• avoid dust, humidity, corrosive gasses and heat
sources
• do not block the ventilation holes: the working
temperature must be between 0...50°C
• surrounding air: 50°C
• use 60/75°C copper (Cu) conductor only, wire size
range 2x N. 22 - 14AWG, Solid/Stranded
• use terminal tightening torque 0.5Nm
Nominal ambient conditions
Before supplying the Indicator with power,
make sure that the mains voltage is the
same as that shown in the last number of
the order code.
Example:
2400 – x – x – x – x – 1 = 100..240Vac/dc
2400 – x – x – x – x – 0 = 20..27Vac/dc
