M-8S - MERIT SERIES PowER CondITIonER • EnGLISH
REAR PANEL FEATURES (continued)
Momentary switches, for example non-latching
push buttons, are momentary contact devices that
maintain their contact position (open or closed) only
as long as the switch is held in a given position.
When the switch actuator is released, the switch
reverts to its normal position (such as the Fuman
RS-2).
A switch of either kind may be used to actuate the
M-8S's remote operation. Maintained switches are
generally most convenient when there is only one
CONNECTING MULTIPLE M-8S UNITS TOGETHER
Multiple M-8S units can be linked together (via their
remote interface) to control additional system needs
or requirements. There are two basic connection
methods for the M-8S; Serial and Parallel. The
connection method you use may be series, parallel,
or a combination thereof and will depend upon the
requirements of your specific installation.
M-8S in Series Mode:
Series mode connection is normally used when
more than three delay stages are needed. Com-
bining M-8S units in series requires an accessory
relay (Furman P/N PS-REL) to trigger secondary
(downstream) units. When connecting M-8S units
in series, the PS-REL is plugged into one of the
DELAY 3 outlets on the primary (upstream) unit and
the relay terminals on the PS-REL are connected to
the remote interface on the secondary (downstream)
unit. When the DELAY 3 outlets on the primary unit
are activated the PS-REL is also activated – which
triggers the sequence to start on the secondary
(downstream) M-8S. Series mode connection can
be repeated for any number of M-8S units. Further
information on the PS-REL can be found on the

remote switch location used to control the M-8S.
When more than one switching location is required,
momentary switches allow the M-8S to be se-
quenced ON or OFF from multiple locations.
Power Indicator:
The POWER indicator is illuminated any time power
is applied to the M-8S. This LED indicates the un-
switched outlets are powered.
M-8S in Parallel Mode:
Parallel mode can be used to activate loads in
excess of 15 Amps by distributing the loads over
one or more M-8S units. When connected in paral-
lel (see Figures A and B, pg. 8) all connected M-8S
units will activate their Delay 1 simultaneously. The
activation times of Delay stages 2 and 3 will depend
upon the delay setting of each unit. If M-8S units
are operating in parallel to increase load capacity,
each unit should be connected to an independent
15 to 20 Amp branch circuit and breaker. If in doubt,
please consult with a qualified electrician to verify
that your facility can support the load currents
required for your installation.
