2.5.2 Removing the Panel Electronics
The ID61/62 Series Panel comprises a removable metal
chassis to which the following assemblies are fitted:
a. Main PSU PCB assembly (which also supports the
user interface fascia and LCD unit)
b. PSU3A assembly.
The Main PSU, user interface fascia/LCD are supplied
as one spared item (kit PN: 020-649). The PSU3A is
supplied as a separate spared item (kit PN: 020-648)
The combined assemblies are located within the back
box, but should ONLY be removed when installing the
back box or if any of the listed items above require
replacement.
CAUTION: The electronic circuits of the ID51/52 Series
Panel use CMOS devices which can be damaged by
static discharge. Suitable precautions MUST be taken
when handling circuit boards.
Procedure
When installing the back box (A), or if it becomes
necessary to remove the Main PCB (B) or PSU3A (C)
assemblies for another reason, follow this recommended
procedure:
1
Remove the cover(s) and store in a safe place, see
Section 2.5.1, Removing the Cover(s)
. Then make
a back-up of the current system configuration,
remembering to disconnect the Earth Fault Monitoring
jumper link (D) at JP6 on the Main PCB.
Note:
The earth connection to the cover fitted in back
boxes incorporates a locking barb (E). To remove
this connection, pull the shroud, NOT the earth
wire, from the earth blade terminal.
2
When fitting any spared items listed above,
isolate
the mains power supply and
disconnect
the battery
interlink wire.
3
At the two-part connector J3, located on the left-hand
side of the bottom edge of the PSU PCB, use a
constant pulling action to disconnect the battery power
supply and thermistor wiring.
4
At the PCB assembly, note the polarity and
connections of all cables and any jumper configuration
settings. Use a screwdriver to loosen all the connector
securing screws. Carefully secure all external cable
tails away from the electronics and from the back box.
5
Using a cross-headed screwdriver, remove the eight
M3 x 10mm SEM screws from the PCB assembly.
Gently lift the PCB assembly clear of the supporting
pillars, place it in an anti-static bag and store safely.
Note:
If the PCB is to be returned to the manufacturer
note its Serial Number and Revision Level (located
along one edge).
