Precautions
Observe these precautions when installing Checker to reduce the risk of injury or equipment
damage:
Do not use Checker in applications where an incorrect or absent output signal •
could cause human injury.
Checker is intended for indoor use only. •
Do not attempt to adjust Checker’s focus when moving parts and/or equipment are pres- •
ent.
Use a listed power supply with an output rated 24 VDC, at least 250 mA, and marked
•
Class 2, Limited Power Source (LPS). Any other voltage creates a risk of fire or shock and
can damage Checker.
Connect the cable shield to earth ground.
•
Make sure that no voltage potential exists between the USB ground on the PC and the •
Checker chassis ground.
An IP67-compliant plug or cable must be fitted to the USB connector for Checker to meet
•
the IP67 protection standard.
Do not install Checker in locations that expose it to environmental hazards such as
•
excessive heat, humidity, impact, vibration, corrosive substances, flammable substances,
or static electricity.
To reduce the risk of damage or malfunction, route all cables and wires away from high-
•
voltage power sources.
Do not extend I/O and power cables longer than 30 meters.
•
Make sure that the mounting screws do not bottom in the mounting holes; using too long •
a mounting screw can damage Checker.
Do not attempt to modify Checker. Modifications will void the warranty.
