3 Mounting at the control cabinet/ building
3.1 Mechanical mounting
POWERLOCK BOXES are designed for standard 19″ rack systems or to dedicated
panel mounts within buildings or remote cabinets. It is recommended that M6
screws / bolts and flat washers are used, and tightened to a torque of 2.94 Nm
min. to 3.43 Nm max. The screws / bolts should be tightened evenly. Adequate
support during assembly must be provided.
If the 19″ rack does not support all IEC 60297 requirements, the use of
additional mounting plates may apply.
3.2 Power installation
Caution: Electrical installations should only be carried out by a suitably
qualified electrical engineer. It is the responsibility of the installer and
user to ensure that the safe practices are adopted.
Power installation: M12 threaded posts on the rear of the unit are for
connecting power cables fitted with cable lugs. Each position is marked on the
back of the box. E (Ground), N, L1, L2 & L3. The threaded posts have a spring
washer and nut that should be tightened to a torque of 27.5 Nm min. to 31.4 Nm
max.
It is recommended that insulated spanners are used when making these
connections.
3.3 Connector for remote sensing
A 2-pole Trident connector is at the back of the POWERLOCK BOX to enable
remote sensing.
The 2 pole connector mounted on the rear is connected to a micro-switch inside

warranty. Ensure that the current rating of the cables and connectors being
used are suitable for
the current rating of the POWERLOCK BOX and connected supply. Do not connect /
disconnect under load!
4.2 Connection with cable connectors
The necessary mating connectors have to be ordered separately and are not part
of the delivery. Recommended cross-sections are printed on the rear of the
box:
400 – 120 mm² and 660 A 240 mm².
1. Use the Allen wrench to open the cover (version with safety cover). 2. The
POWERLOCK connectors are plugged sequentially in a row. Starting on the left
with
the Ground/Earth connection (Green) going to the right with N, L1, L2, L3. 3.
Insert the Ground (Green) connector, aligning the “PUSH” arrow on the label of
the con-
nector in a 12 o´clock position. Fully insert the connector until it bottoms
in the cavity and turn through 45 degrees clockwise until the connector locks
with an audible `click’. 4. Repeat the above process for the Neutral connector
and the rest of the connectors. If at any time a connectors does not rotate
fully, check if the previous connector is fully turned. 5. The lock is located
to the right of the L3 connector on the front panel. The needed square drive
