Power connection
Power is supplied to the panel via the input socket (see
D
in Figure 1 on page 6). This socket accepts an
Amphenol C016 20 D 003 100 12 cable connector (female, IP67- rated).
Power can be relayed to another LC Plus panel via the throughput socket (see
E
in Figure 1 on page 6).
This socket accepts an Amphenol C016 20 H 003 100 12 cable connector (male, IP67- rated).
Warning! A maximum of five LC Plus 2140 panels in total or ten LC Plus 1140 panels in total may
be interconnected using power throughput connectors to form one chain that draws power via
the first panel’s power input cable.
Two types of power input and power throughput cable are supplied with each panel (see Figure 8):
• EU color-coded cables fitted with connectors with a black shell. You must use these input and throughput
cables when using single-phase AC mains power.
• US color-coded cables fitted with connectors with a blue shell. You must use these input and throughput
cables when using two-phase AC mains power.
All cables are 16 A rated, UL-listed, 16 AWG.
Table 1 on page 15 gives details of the standard wiring color codes used in these two cable types, as well as
common pin identification symbols. If you have any doubts about proper installation, consult a qualified
electrician.
Separate Amphenol connectors and replacement power cables with Amphenol connectors installed are
available from your Martin supplier.
The supplied power cables can be replaced with cables from other sources, but replacement cables must be
3-conductor with a Hypalon or neoprene rubber jacket, approved for a current of 16 A and temperature of
90° C (194° F) minimum. Replacement cables must also be minimum 16 AWG and UL-listed in North
America or have conductor size minimum 1.5 mm² in other regions.
To connect an Amphenol power cable connector to an LC Plus panel, line up the keys in the cable connector
with the slots in the corresponding chassis connector in the rear of the panel base (
D
or
E
in Figure 1 on
page 6), push the cable connector firmly into the chassis connector, then twist the locking ring on the cable
connector clockwise to screw the connectors together and form a waterproof and dustproof seal.
Any connectors that are not being used must be sealed with their caps at all times.
There is no power on/off switch on LC Plus panels. Apply and shut down power using an external switch at
the power outlet or at the main switchboard. Make sure that the external switch is near the panels and easily
accessible so that power to the panels can easily be shut down if necessary. Do not power panels on or off
by inserting or removing live power connectors, as this will cause arcing at the connector contacts that may
damage devices and connectors.
