Installation Location

The UNIPRO instrument is designed for 1/8 inch panel mounting in a DIN standard opening of 5.43 inches square (adapter panels available by special order). Required rear clearance is 10.5 inches to allow for wiring. As with all solid state equipment, the controller should be away from excessive heat, humidity, and vibration (refer to specifications). Since the unit uses red LED display devices, avoid placing it in direct sunlight to reduce interference with the display's visibility. The instrument requires 100/120/200/240 VAC (jumper selectable on power interconnect board inside the rear panel) 50/60 Hz. It should not be on the same circuit with other noise-producing equipment such as induction machines, large electrical motors, etc. All instrument wiring must be run separate from all control wiring.

Panel Mounting/Removal

Because the instrument uses a ventilated enclosure, it is not dust-tight and should therefore always be mounted in a sealed control panel. To mount the UNIPRO in a control panel, a hole must be cut 5.43 inches square in the necessary location on the panel. The following procedure should be followed to mount the UNIPRO in the panel.

1.Insert the unit into previously cut out 5.43 inches square hole in the panel.

2.While supporting the unit, insert one slotted clamping bracket, with head of the bolt facing to the rear of the unit, into the 0.62 inch by 0.82 inch cutout on the side of the unit.
