Table 1: Model 580A 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.
•
It is recommended that a wiring service loop be used to facilitate gaining access
to the alarm set points.
•
Care should be taken to assure adequate ventilation.
•
Do not mount the controller in a manner, which restricts the natural convection
airflow from normal ambient air.
•
The controller operating temperature range is 0
°
C to 60
°
C (32
°
F to 140
°
F).
2.2 Power Connections
The system operates on nominal line power of 115 VAC, 50/60 Hz. Power must remain
disconnected until all other wiring connections are made.
NOTE:
To eliminate accidental system shutdown, GMI does not provide a power on/off
switch.
The following are wiring guidelines for the 580A Controller:
•
If AC is to power the system, connect the line power supply to the terminals
L
,
N
,
located on the rear of the controller. Use accepted commercial wiring practices.
•
Primary DC power may be used instead. Use any 24V nominal direct current
supply with a minimum rating of 2 amperes.
