Table 1: Model 2280A Mounting Parts
The following are guidelines for mounting the controller:
•
To minimize the possibility of electrical shock, mounting must be as free from
shock and vibration as possible, in a grounded enclosure that requires a tool
for instrument removal.
•
Even though the controller is RFI resistant, do not mount the controller in
close proximity to radio transmitters or similar equipment.
•
Care should be taken to assure adequate ventilation.
•
Do not mount the controller in a manner that restricts the natural convection
airflow from normal ambient air.
•
The controller operating temperature range is 0
°
C to 60

2.2 Power
Connections
The Model 2280A operates on a nominal line voltage of 117 VAC, 50-60 Hz, 220
VAC operation is optionally available.
Note:
To eliminate accidental shutdown, GMI does not provide a power ON-OFF
switch. Power must remain disconnected until all other wiring connections
are made.
The following are wiring guidelines for the 2280A Controller:
If AC is to power the system, connect the line power supply to the terminals
L, N
, and
GND
located at the rear of the controller. Use accepted commercial
wiring practices.
Primary DC power may be used instead. Use any 24VDC nominal supply
with a minimum rating of 2 amperes.
