LTC 9383/20 and L TC 9388/20 Housings
These housings are to be connected to 24 VAC only,
and are designed to be used where site power is 24
volts.
Use only where IEC (CE) approval is NOT
required. If IEC approval is required use /10
or /50 versions.
The LTC 9383/20 and LTC 9388/20 are designed to
be used with 24 volt cameras only.
Connection of these housings to supply voltage in
excess of a nominal 24 VAC source will cause
damage.
The internal isolation transformer provides 24 VAC for
camera power. The transformer provides flying leads for
connection to the primary (white wire/pin 1, black wire/pin
6) and the secondary (white/black striped wires-pins 7 and
12). The housing is shipped with the heater/defogger
connected to the primary. No installer interface is
required. See Figure 13.
1.
Connect the supply (24 VAC) to the primary flying leads
of the transformer. Use the wire nuts provided for this
connection. See Figure 13.
2.
Connect the secondary flying leads to the camera's
24 volt input. See wiring diagram Figure 13 for
clarification and Figure 9 for power connection
drawings.

LTC 9383/10 and LTC 9388/10 Housings
These housings are to be connected to 24 VAC only,
and are designed to be used where site power is
24 volts.
Use where IEC (CE) approval is required.
The LTC 9383/10 and LTC 9388/10 are designed to
be used with 24 volt, 50 Hz cameras only.
Connection of these housings to supply voltage in
excess of 30 VAC source will cause damage.
Do not remove the transformer insulator.
No user serviceable parts are underneath.
The internal isolation transformer provides 24 VAC for
camera power. A terminal block provides connection to the
transformer via leads to the primary (blue wire/blue
terminal/pin 1, black/fuse/grey terminal/pin 6). The
transformer secondary is white/black striped wires on pins 7
and 12. The housing is shipped with the
heater/defogger connected to the secondary. No
installer interface is required. See Figure 14.
1.
Connect the supply (24 VAC) to the terminal blocks.
Use only the terminal block provided for this
connection. See Figure 14.
2.
Connect the secondary flying leads to the camera's
24 volt input. See wiring diagram Figure 14 for
clarification and Figure 9 for power connection
drawings.

LTC 9383/50,L TC9388/50 Housings
These housings require connection to 230 VAC, and are
designed to be used where site power is 230 volts.
The LTC 9383/50 and LTC 9388/50 housings can easily be
used with either 230 volt or 24 volt cameras.
The internal transformer provides 24 VAC for both the
heater and 24 volt camera power. A terminal block provides
connection to the transformer via leads to the transformer
primary (blue wire/blue terminal/pin 1, black/fuse/grey
terminal/pin 6). The transformer secondary is white/black
striped wires on pins 7 and 12. The housing is shipped
with the heater/defogger connected to the
secondary. No installer interface is required.
Do not remove the transformer insulator.
No user serviceable parts are underneath.
Installing a 230 volt camera into the LTC 9383/50 or
LTC 9388/50 housing requires the camera's line cord to be
cut and connected with the transformer's primary wiring and
the power supply line. See Figure 15.
1.
Cut the power cord leaving enough cable to allow
connection to the primary (approximately 5 inches).
Strip no less than 6 mm (0.25 in) and no more than
8 mm (0.31 in) of insulation away from the wire, be sure
not to nick the wires. Connect the supply line to the
camera power cord and transformer primary leads. Use
only the terminal block provided for this connection.
2.
The secondary flying leads (white/black striped) will not
be used in this application and should be taped to
prevent shorting. See wiring diagram Figure 15 for
clarification and Figure 9 for power connection
drawings.
