CAUTION!
• Remove power to unit before wiring input and output connections.
• Follow instructions carefully to avoid personal injury.
• This product should only be used for the purposes and in the manner described in this manual.
Installation
1. Punch out panel and de-burr edges. Recommended
clearance on all sides between instruments is 1 inch.
2. Place gasket on instrument, and install in panel.
3. Slide mounting bracket over back of instrument until
quick-clips snap into latches on side of instrument.
4. Connect wires to terminals.
5. To remove, secure instrument temporarily with tape from
front or grip from rear of instrument. DO NOT RELEASE.
Press quick-clips outward and remove.
6. If cleaning is necessary, wipe the front of the unit with a
damp cloth.
7. The live contacts on the back of this unit must be covered
to avoid accidental shock hazard.
