INSTALLATION OVERVIEW
INSTALLATION OVERVIEW
The Keypad and PowerMate units should be inspected for physical damage before installation. Any cracked, broken
or bent items on either unit should be reported to your local dealer of DSSA for proper disposition.
Ensure all power is off by disconnecting the battery(s) from the system or de-energizing the battery switch.
Prepare the unit for installation by removing all packaging materials. Keypads must be mounted to a flat surface
using a properly positioned cutout for the keypad connector pigtail. The keypad mounting studs should be secured
through the panel using 10-32 UNF nut and lock-washer. Tighten the nuts to snug only.
Do NOT exceed torque ratings as advertised of 7 1 in. lbs or 0.79 N.m as this will crack or deform the keypad,
which will cause intermittent operation.
Connect the keypad pigtail Deutsch connector to the wire harness (wire harnesses are not provided by DSSA). They
must be designed, manufactured and installed to meet the DSSA requirements as well as the specific design
requirements of the application, for length, termination, wire size, etc. It is the installers responsibility to ensure this
has been done to meet or exceed design specifications.
To mount the PowerMate, the unit must be installed in a dry, well ventilated space inside the vehicle cabin. The
ambient temperature must not exceed 70°C. It is recommended that the PowerMate be mounted with the plugs
facing in a downward direction or to the rear of the installation to minimise potential damage to the plugs, harness
and studs.
Secure the PowerMate with four bolts, nuts and washers or equivalent wood screws (not provided).
Secure the negative power side terminal to the negative power lug and secure with the nut and washer provided.
Secure the positive power side terminal to the positive power lug and secure with the nut and washer provided. Take
care to never reverse the terminal connections or reverse the order of connection.
Do NOT exceed recommended torque ratings as advertised of 12 3 in. lbs or 1.36 N.m. Over tightening will
cause the lug nut to crack or fail.
The main battery supply to the PowerMate must be protected by a switchable circuit breaker positioned at the
battery. This enables the PowerMate to be isolated from the battery in the event of charging or changing the
battery(s).
The PowerMate 8 is limited to a maximum voltage supply of 30 volts.
Plug Deutsch connectors (ensuring the correct key is selected) and then apply battery power. The system is now
ready for power and operation. Re-connect the main battery(s) to the circuit and follow the operational instructions
below.

When a button on the keypad is pressed, the circuit for that button will turn on. The indicators on all keypads for that
circuit will light up to show circuit is on. Any DSSA Keypad can turn a circuit ON or OFF.
If a circuit draws more than the rated current, the circuit will be turned OFF and the indicator LED will flash to
indicate circuit was Tripped, To REST the circuit, Press and Hold the Keypad button down for 6 seconds.
The system will also detect and indicate faulted circuits. A faulted circuit can be wither an open circuit such as a
defective device (burnt out bulb) or dead short circuit. When an Output fails, the operator can Press and Hold the
Keypad button with the Flashing LED for 6 seconds, to REST the Output. The Output can now be tried again.
GENERAL FUNCTION
GENERAL FUNCTION
To un-install the PowerMate from the system, the steps taken should be the reverse of the installation sequence.
Do NOT disconnect the power terminals while the Deutsch connectors are still attached.
Failure to disconnect the Deutsch connectors first, may cause the PowerMate to receive reverse current causing
failure of the unit and voiding any warranties.
