Step 1- Fit load cable clamps
• Insert the square ends of the load cable
clamps into the holes in the back of the
system.
• Engage two turns of each retaining screw.
This will ensure that the clamp does not
move when the wires and sleeves are
inserted.
‡
Fit all clamps even if you do not use them
all. Tighten unused clamps to prevent access
to the dc outputs.
Step 2 – Strip cable ends
• Strip approximately 10mm (3/8”) from the cable ends. We recommend fitting cable
ferrules over the cable ends.
Step 3 – Fit cable and sleeves
‡
To maintain safety approvals insert only the following numbers of cables per clamp, with
sleeves where applicable. This will ensure that cables are retained correctly in their clamps.
• Feed the cables through the clamps as follows, depending on cable size.
1mm 2 (18 AWG) – 2 cable pairs* per clamp:

2 x 5mm sleeves
 10mm sleeve
‡
* If only one cable pair is required
then use a dummy pair with sleeves
to make up the space.
4mm 2 (12 AWG) – 1 or 2 cable pairs per clamp.
Step 4 – Terminate cables
• Terminate the negative load cable(s) at the (-) terminal block(s) of the dc outlet(s).
• Terminate the positive load cable(s) at the (+) terminal block(s) of the dc outlet(s).
• Tighten the terminal screws. Required torque: 0.4 – 0.6 Nm (3.5 – 5.3 lb-in).
‡
Ensure that the polarity at the dc outlet(s) matches the power input polarity of your equipment.
Connecting reverse polarity equipment power cables to the dc outlets of a power system might
cause damage to your equipment. Such damage is not covered by our warranty.
‡
Ensure that the correct cable sizes have been used (1mm2/18 AWG for 6 A outlets and
4mm2/12 AWG for 25 A outlets).
