Install open-frame drives in an enclosure with a volume at least three times the volume of the open-
frame drive.
Do not mount controller where ambient temperature is outside the range of -10 to 45 °C (14–13 °F).

Externally fuse the +Battery input line with Littlefuse 314 series or Bussman ABC series or equivalent
fuses designed for use with motors and motor control systems; rated for the lesser of:
1) 200% of the continuous current rating of the drive, or 2) 150% of the motor full-load current.
(Fast-blow fuses are NOT recommended.) (AutomationDirect sells ABC series fuses.)

Please note the following recommendations
regarding the Current Limit (Trip) Output and Setting:
•
The Current Limit Output can be used to inhibit the
drive or break the power connection to the drive�
•
The Current Limit Output threshold is the same as
the Current Limit Setting�
•
To properly adjust the CURRENT LIMIT Setting, a DC ammeter should be placed in series with the
armature line� This meter can be removed after the DC Drive is adjusted�
•
The Current Limit Output is immediate, without time delay, and is NOT retentive�
•
Use with 12VDC relay� In order to maintain a current limit fault, use a latching relay�
•
Source voltage from terminal P2-1�
•
Current Limit Trip Output sinks to terminal P2-4 (50VDC@0�3A)�
•
Recommended use with Inhibit, terminals P2-4 and P2-5�
•
If you connect the current limit relay to the Pot HI (P2-1), supply voltage will be 10V, regardless of the
supply voltage to the drive� If the relay is connected to the supply voltage, the relay voltage needs to
match the supply voltage� The Current Limit Output is capable of up to 100V�
