Installing Your 1394 (applies to all systems) 2-11
Mounting Your 1394-DCLM Two 1394 system power buses can be linked by connecting two
DCLMs together. This procedure is application specific and requires
proper implementation. Please contact your Allen-Bradley sales
representative for more information.
When using the 1394-DCLM for energy storage, the power plug must
be installed (refer to Figure 2.10 for location).

Mounting the External Shunt
Resistor for 5 and 10 kW System
Modules If your 5 or 10 kW 1394 system module requires a means of
dissipating regenerative energy that exceeds the capacity of the
internal shunt resistor, install a 1394 External Shunt Resistor Kit
(catalog number 1394-SR10A).
To install the 1394-SR10A Shunt Resistor Kit use two M10 (3/8 in.)
bolts and mount the external shunt resistor assembly vertically on a
flat rigid metal surface that will not be subjected to shock, vibration,
moisture, oil mist, dust or corrosive vapors.
Note: To extend the leadwire length up to 15 m (49 ft total overall
length), use MTW, 105
°
C, (302
°
F) Class H insulated wire (UL
styles 3349, 3374, or equivalent).
Mounting External Shunt Modules
for 22 kW System Modules If you are using a 22 kW system module, you must use a shunt
module (1394-SR9A, -SR9AF, -SR36A or -SR36AF). An external
shunt module is required for 22 kW system modules because there is
no internal shunt resistor.

ATTENTION: To avoid the hazard of shock or burn
and ignition of flammable material, appropriate
guarding must be provided. These resistors can reach
