what you ordered.
■INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
POINTS OF CAUTION
■POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 240V AC rating: 85 – 264V, 47 – 66 Hz, approx. 11VA
24V DC rating: 24V ±10%, approx. 250mA
■GENERAL PRECAUTIONS
• Before you remove the unit or mount it, turn off the power
supply for safety.
■ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -5 to +55°C
(23 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
■WIRING
• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
• Be sure to close the terminal cover for safety.
■AND ....
• The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

When the unit is located at the end of transmission line via twisted-
pair cable (= no cross-wiring), short across these terminals.
Do not short them for the one not located at the end.
When the DAL4 is to be connected with the 22LA1 or DLA1 multi
transmission devices,do not connect the shield wire to the SG
(4, 8 or 16) but to the FG at the instrumentation panel.
Grounding the FG improves noise immunity of the power and
transmission lines, and is a recommended practice when the DAL4
is installed where a noise is present.

WIRING INSTRUCTIONS
■SCREW TERMINAL
Torque: 0.8 N·m
CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
9 – 10 with a multimeter.
3) Twisted-pair cable: CPEV-0.9 dia. or larger. Check that
the (+) are connected to (+), (–) are connected to (–).
4) Twisted-pair cable ports: When the port is located at the
end of a transmission line, or unused, short across the
terminating resistors (2 – 3, 6 – 7 or 14 – 15).

Notes
• Be sure to use lightning surge protectors (model: MDP-DM3) on twisted-pair cables.
• Be sure to connect the terminal No. 1 of the MDP-DM3 with SG terminal of the DAL4.
• For connecting model DLA1 or 22LA1 with the DAL4 in the same panel, install them between the MDP-DM3 and the DAL4.
Be sure to connect the terminal No. 1 of the MDP-DM3 with SG terminal of the DAL4.
• Lightning surge protectors for power supply line are recommended for complete protection.
