Mounting Recommendation
Locate the SPD as close as physically possible to the node/equipment to
be protected, thereby limiting lead length and ensuring lower let through
voltages on the protected equipment. For every foot of wire length,
approximately 1 nanosecond of turn-on/turn-off time will be added, and
approximately 175 volts (6kV/3kA,8/20 microseconds) will be added to the
clamping voltage.
