Installation Check List
ATTENTION: Dangerous voltages will be present on the MiniDySC terminal block while in service. The MiniDySC is intended
for use as a component of complete equipment and should not be separately installed in the field. The user must assure a
safe operating environment.
ATTENTION: Metallic contamination inside the MiniDySC enclosure will void the warranty.
Before proceeding, please take a few minutes to review the necessary steps:
• All packing materials and restraints have been removed
• All cables are properly routed
• All power cables are properly terminated
• Properly installed ground connector
• Properly terminated neutral connection (if required)
• Clean, dust-free work space with adequate lighting
• Mount the MiniDySC in an upright orientation with at least 2” (50 mm)
clearance above and below for proper cooling- see Figure 1
• Take care to prevent metallic particles from entering the vent holes
• Operational checks have been reviewed and completed
• The MiniDySC may be DIN rail or panel mounted within an enclosure as
long as the ambient temperature remains at or below 40 °C
and Figure 2.
Inspecting and Unpacking
Location (Environment)
• Carefully inspect the outer packaging for evidence of damage during
transit. Do not install a damaged cabinet. Report any damage to the carrier
and contact your local sales or service immediately.
• Check the MiniDySC label for correct model number with the packaging
list to ensure you have received the correct voltage, current, and wiring
configurations.
• After removing the packaging material, inspect the contents for any
evidence of physical damage, and compare each item with the Bill of
Lading. If damage has occurred or shortages are evident contact your
carrier immediately.
NOTICE: Install this equipment in an indoor temperature-controlled area, free from
condensation and conductive contaminants such as carbon dust.
The MiniDySC must be installed in a protected environment. The location must
provide adequate airflow around the MiniDySC in an atmosphere free from
excessive dust, corrosive fumes, or conductive contaminants. Do not operate the
MiniDySC in an environment where the ambient temperature or humidity is
beyond the specified limits given in this manual.

Mounting Instructions
DIN Rail Mount
Figure 1 - DIN Rail Mounting 1. Mount on a 35 x 7.5 mm DIN rail that conforms to the EN 50022
standard.
2. The DIN mounting clips come pre-assembled to the back of the unit.
3. Hook the top edge of the mounting clips over the top flange of the
DIN rail.
4. Pivot the MiniDySC down until the unit latches to the DIN rail.
5. To secure the MiniDySC to the DIN rail assemble the locking clip to the
top of the MiniDySC with one (1) of the #6 sheet metal screws supplied.
See Figure 1
6. An alternative method to using the locking clip to secure the MiniDySC to
the DIN rail is to use the lower panel-mounting bracket. Prior to mounting
the unit to the DIN rail install the lower panel-mounting bracket as
outlined under “Panel mounting instructions”. Once the unit is latched to
the DIN rail the unit can be secured to the mounting panel with a screw as
described under the panel mounting instructions.
.
Panel Mount
Figure 2 - Panel Mounting 1. The MiniDySC may be panel mounted with the supplied hardware.
2. Do not remove the DIN mounting clips.
3. Attach the two (2) panel mounting brackets to the MiniDySC with four
(4) #6 sheet metal screws supplied. See Figure 2
4. The panel mounting brackets were designed to accept #8 - #10 hardware
with a maximum head diameter of 0.375" (9.5 mm).
5. The center-to-center vertical mounting dimension for screw location is
8.65" (220 mm) on the 250 VA rated MiniDySC models and 9.65" (245
mm) on the 500 VA and 750 VA rated models.

Operating Indicators
• The alarm contact will change states during any alarm condition. When the
alarm condition has cleared, the alarm relay will return to its normal state.
• Terminal block pin numbers and Alarm contact ratings are shown in Figure 5
Operation is as follows:
– Normal Line Condition: pin 1 connects to pin 3.
– Alarm Condition: pin 1 connects to pin 2.
– Power Off Condition: pin 1 connects to pin 2.
Figure 5 - Alarm Contact
The service disconnect or the external branch circuit breaker may be used as a
master on/off switch.
• When power is switched on, the Green light (Normal) on the front of the
MiniDySC will be lighted. The green light indicates that the output voltage
is within a normal range of -13% to +10% of nominal. This indicator will
also be on during sag correction events since the MiniDySC will be
maintaining the output voltage.
• The Amber light (Alarm) flashes when the MiniDySC correction function
is inhibited. See Alarm Codes section below. The MiniDySC will resume its
corrective function and the flashing light will turn off when the alarm
condition has ceased. In a flashing amber light condition, the MiniDySC
will continue to pass the utility power to the load via the static switch.
• The Red light will be on when the Static switch is inhibited due to an
overload condition. The MiniDySC will open the output. Power will need to
be cycled to reset the MiniDySC.

Alarm Codes
Alarm LED Flash Sequence
While the MiniDySC is in the alarm state due to a non-fatal alarm, the amber
LED will flash the alarm code sequence at 1Hz where the number of flashes
equals the alarm code. There is a two-second delay, after which the code will
repeat if the error condition persists. This group of alarms are those that the user
can act to correct, such as an overload or input over-voltage.
Some alarms cannot be corrected by user action. These alarms may require service
by a qualified technician. For such alarms the amber LED will flash continuously
at a faster 6 Hz rate.
