1.3 EQUIPMENT DESCRIPTION
This Digital Load Module (DLM) is used to control or turn on and
off a load under the control of the Load Shed Module (LSM) in the
transfer switch.
The DLM consists of a 2-pole N.O. relay mounted in an enclosure.
The 2-pole relay is rated to control:
Current – 55 resistive or 40A inductive.•
Voltage – 600 Vac.•
Motor Rating – 3 hp @ 240 Vac.•
LRA – 240 Amps @ 240 Vac.•
Coil Voltage – 120 Vac (0.06A holding current)•
The enclosure is non-metallic and is rated UL type 3R.
A UL type 3R enclosure primarily provides a degree of protection
against falling rain and sleet; is undamaged by the formation of ice
on the enclosure. It is suitable for mounting indoors or outdoors.
The DLM module is UL listed as industrial control equipment, to
U.S. and Canadian safety standards.
Several crimp-on connectors are supplied for use in making the
contactor coil connections (1/4” quick connect) and grounding
terminal connections (1/4” ring terminals). Note: Use yellow
colored insulator terminals for #10-#12 AWG wire, blue colored
insulator terminals for #14-16 AWG wire.
1.4 TRANSFER SWITCH DATA
DECAL
A DATA DECAL is permanently affixed to the DLM enclosure. Use
this DLM only within the specific limits shown on the DATA DECAL
and on other decals and labels that may be affixed. This will pre-
vent damage to equipment and property.
When requesting information or ordering parts for this equipment,
make sure to include all information from the DATA DECAL.
