NOTE: The plastic cable ties surrounding the
air pump are to ensure safe handling during
shipment. Remove before operating the unit.
Reinstall a plastic cable around the air pump if the
unit is shipped back to Emerson Electronics and
Solutions for service or repair. This prevents damage
during shipment.
3.6. RLDS Electrical Wiring
The RLDS uses a universal power supply that is
capable of accepting inputs of 100 to 240 VAC, 50/60
Hz. The monitor's power consumption is 20 Watts. It
is highly recommended that the monitor be connected
directly to the AC power source, preferably on its own
circuit. The AC power connection should be
completed with UL approved 3-conductor wire
(minimum 16 AWG), rated 300 VAC at 221°F
(105°C).
Locate a convenient service knockout and install
electrical conduit in the typical manner.
Locate the AC Input Terminals and Ground Stud on
the inside of the monitor (Figure 3-7). Secure the
incoming AC power neutral (white/blue) and live
(black/brown) wires to the LINE 1 and LINE 2
terminals.
Using the supplied crimp-on ring terminals,
washers, and nuts, connect the incoming AC power
ground wire (green) to the monitor's AC input ground
stud, and then install a separate wire between the
ground stud and the GND terminal.

Locate the AC power connector on the inside of the
instrument and remove it from the circuit board.
Secure the wire leads to the connector orienting them
as shown in the diagram. Carefully plug the connector
back onto the circuit board. finally, locate the ground
lug and securely fasten the ground lead.
A second connector is provided to wire an external
device through the RLDS power circuit. Locate the
connector and complete the wiring as described
above.
3.6.1. Warnings and Cautions
wire must first be connected to the monitor's ground
stud. Doing so poses a potential shock hazard and is
also a violation of electrical safety standards applicable
to this type of equipment.
• A switch or circuit breaker rated 1.0 A, 250
VAC must be attached to the unit's AC power
leads.
• This switch must also be located in close
proximity to the monitor, and be within easy
reach of the operator.
• This switch should also be clearly marked as
the unit's main AC disconnect device. The
circuit breaker or switch must disconnect all

WARNING: Electrical installation should be
performed by a certified electrician and must
comply with all applicable local, state, and
federal electrical safety codes.
WARNING: Under no circumstances should
this instrument be operated without connection
to a protective ground. The AC power ground
WARNING: Copper conductors for
connection to supply mains must be made in
accordance with NEC/CEC and local codes.
WARNING: Drilling holes in the RLDS
enclosure may damage the unit and will void
the warranty. Only use the knockouts provided
for electrical connections.
