Wire and Cable Length
Restrictions
Connecting DC Power
The following wire and cable length restrictions apply to DTAM products
that are CE marked when used in installations that require compliance to
European EMC Directive 89/336:
DC Power Wiring
Ground Terminal Wire
Communication Cables
These restrictions apply to the following Catalog Numbers:
•
2707–M232P3 Series E
•
2707–M485P3 Series E
The DTAM Micro accepts power supply voltages from 18 to 30 VDC (use
isolated DC power supply capable of providing at least 200 mA). Connect
the DTAM Micro directly to the power source or use either of two AC to DC
Adapters depending upon the source voltage.
•
120 VAC Input, use AC to DC Adapter (Catalog No. 1747-NP1)
•
240 VAC Input, use AC to DC Adapter (Catalog No. 1747-NP2)
To connect the DTAM Micro to a power source:
ATTENTION: Verify that the power is disconnected from the
power source before wiring. Failure to disconnect power may
!
result in electrical shock.
Make sure that the supply voltage to the DTAM Micro is 18 to 30
volts DC. The incorrect voltage may damage the DTAM Micro.
Do not overtighten the power connector screw terminals.
Overtightening the terminals may damage the DTAM Micro.
1. Make sure that the voltage source is not turned on.
2. Use AWG#16 or #14 stranded wire to connect the DTAM Micro screw
terminals to the DC power source (see below).
Note: The terminal block on the DTAM Micro is not removeable.
