APC MODULAR PANEL PRODUCTS Surge Protective Device (SPD)

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.
