External Disconnect
•
Install an external disconnect switch or circuit breaker that meets local standards.
•
Position the SSK
513
in an accessible location.
•
Position and identify the disconnect device so as to provide safe and easy operation.
•
Label the disconnect device as being for the SSK
513.
AC Power Wiring
For the AC power connections, use three wire-sheathed cable with an overall cable diameter of 0.2…0.45 inch (5…12 mm).
For signal output, use 18…22 gauge (0.25…0.75 mm
2
) shielded wire. Overall cable diameter between 0.12…0.35 inch
(3…9 mm).
To prevent accidents, connect main power only after all other wiring has been completed.
The amplifier is a microprocessor device. It is important that the power supply be as “clean” as possible. Avoid using power
lines that feed heavy loads: pumps, motors,
etc.
If dedicated lines are not available, a filtering or isolation system may be
required.
Power wiring is the same for meter mount and remote mount amplifiers.
Remote Mount Installation
If you are installing the SSK
513
amplifier in a remote location, review the procedures in this section.

Wiring Configuration
Wiring between the detector and the SSK
513
amplifier comes complete from the factory. If your installation requires the use
of conduit, we recommend that you follow these steps when wiring the detector to the amplifier.
1. Remove the junction box lid. Carefully remove the wires connected to the terminal blocks that run to the SSK
513
. See the chart below for a reference of wire color to terminal connection.

supplied.
3. Complete conduit assembly on both ends and rewire the cable into the junction box as it was previously wired.
