Grounding
Grounding
*1. The MD7DP is not applicable to protect two-wire transmitters. To protect two-wire transmitters,
model MD7ST designed to yield only small leakage current is suitable.
Confirm the polarity of the terminals when connecting this module to a protected device.
*2. Use a DC power source with the overload current protection function. (maximum output current 1.2A)
*3. Install a current limiting element (capacity 1.2A) when the output current exceeds 1.2A.
*4. Oxide coating of an aluminium rail may lower the electric conductivity between this module and the ground.
Use a steel or copper rail.
*5. Be sure to ground the DIN rail. Recommended grounding resistance ≤100
*6. Cross-wire between the DIN rail and the metal housing of the protected device to equalize the earth potential.
Ground only the surge protector when the protected device has no ground terminal.
Specifications are subject to change without notice.
