3-10 KSU Installation
Chapter 3 - System Installation
Power Line Surge Protection
The AC outlet should be equipped with an additional power line transient surge protection
device. Systems using such devices are more resistant to damage from power line surges
than unprotected systems. Power line surges often occur during switching operations and
especially during violent thunderstorm activity.
Protector Specifications -- Installation of a surge protector meeting these specifications
prevents or minimizes the damage resulting from power line surges.
†
The Isolation Transformer/Surge Protector shall be a 15 amp self-contained unit that
plugs into a standard grounded 117 VAC wall outlet.
†
The wall outlet must be designed to accept a 3-prong plug (2 parallel blades and ground
pin).
†
The protector should be fast operating and capable of protecting transients greater than
200 volts.
Lightning Protection
The system provides secondary protection per UL 1459 Specifications. Primary protection
circuitry is the installers responsibility and should be installed per the National Electric Code
(NEC).
KSU AC Power Plug
1. Before plugging the KSU power cord into the AC source, verify that the Power switch on
the AC/DC front panel is in the OFF position.
2. Plug the KSU power cord into the AC outlet and turn the AC/DC Power switch to ON. The
red/green LED on the PSUs should illuminate.
It is recommended that the AC outlet be equipped with an isolation transformer/
surge protection device that utilized MOV protection.
