3 MOUNTING
3.1 Electrical connections
There are two terminal blocks located in the circuit board
inside the LCP9H (see Fig. 4). LOOP terminals are for connec-
tion to the VG9000H and PWR terminals are for the 24 V DC
power supply or for the loop power.
NOTE: The VG9000H version to be used with LCP9H prod-
ucts needs to have type code option L2. The VG9000H ver-
sion to be used with LCP9H_L products needs to have type
code option L3.
In VG9000H the LCP connection terminals are located in the
upper housing.
See the VG9000H manual 7VG9H70EN for detailed electrical
connections in the VG9000H.
4 LCP9H LAYOUT AND FUNCTIONALITY
The LCP9H front panel layouts with push buttons and LEDs
can be seen in Fig. 5–8.
The push buttons (described in the Section 4.1) are as follows:
Open
PST
Close (not available in W version)
The LEDs (described in the Section 4.1) are as follows:
Ready-To-Open(amber)
PST (amber)
Open (green)
Closed (red)
FAULT (white)
NOTE:
The tightening torque for the cover screws of LCP9HE_
versions is 16 Nm.
NOTE:
The enclosure of the LCP9H meets the IP66 protection
class according to EN 60529 in any position when the
cable entries are plugged according to IP66.
Based on good mounting practice, the recommended
mounting position is with electrical connections placed
downwards. If these requirements are not met, and the
cable glands are leaking and the leakage is damaging the
LCP9H electronics, our warranty is not valid.

NOTE:
When installing the LCP9H, standard IEC 60079-14/12.2.4
should be considered. The circuits of the apparatus are
assumed to be earthed.
