WARNING!
The X-1200 equipment must be externally grounded using a
customer-supplied ground wire before power is applied. Contact
the appropriate electrical inspection authority or an electrician if
you are uncertain whether suitable grounding is available.
Always ensure that the power is OFF before connecting or
disconnecting power to the unit.
To connect the HM or RBM to a DC power source, follow these steps:
1.
Verify that the equipment is properly grounded as described in the Section 6.7, “
Overvoltage Protection Instructions
2.
Turn off power to the DC power source at the designated circuits.
3.
Align the DC power cable connector with the two-prong key inside of the DC power connector
receptacle on the module, then push the cable connector into the connector receptacle and hand
tighten the connector screw until fully seated.
4.
Connect the other end of the DC power cable to the -48 Vdc supply, ensuring that you comply with
the electrical codes for your installation location. For installation, use the white wire to connect to
RTN, and use the black wire to connect to the -48 Vdc supply. The termination method you use
depends on the power source, for example, a junction box, at your installation site.
5.
Verify the power connection cable run is weatherproof. Use a conduit in open locations to further
protect the DC power cable run to the installation location against physical damage.
6.
Turn on DC power at the designated circuits. The module starts up and loads the operating software.
