INSTALLATION
Inspection
All units are completely assembled, inspected and tested at the factory prior to shipment. Upon receipt of the unit,
a visual inspection should be conducted to detect any damage that may have occurred during shipment. Report
any discrepancy to the factory immediately.
Physical
All Model AN25 units are enclosed in a ¼ DIN, molded plastic housing. The housing has a snap on the front
Bezel, removable mounting clips, and a plug-in wiring terminal on the back.
Refer to dimensional requirements for dimensions, bezel size, and depth needed for mounting the instrument in a
user panel. Be sure to provide additional space for cabling and connections behind the instrument. Additionally,
all wiring to the back of the instrument should have sufficient service loops to allow for the easy removal of the
instrument from the panel.
Electrical
An input supply voltage of 110VAC or 12VDC is standard for the Model AN25. Be sure to observe correct polarity
when making field terminations.
Model AN25-L requires a minimum loop voltage of 6.5V + (.02 x RL). Maximum voltage is 28V + (.004 x RL).
Signal
The standard signal cable is a 2 wire shielded cable with a MS3102 connector termination which is the industry
standard interface for 2 pole pickup coils. The shielding is singly ended and should not be altered.
