Storage
It is recommended that the unit be stored in its original shipping
box/crate until it is to be installed.
The unit should be stored in a location where:
The ambient temperature is between –13° to 140°F (–25° to 55°C)
•
The relative humidity is between 0% and 95%, noncondensing
•
The environment is dry, clean, and noncorrosive
•
The unit will not be subjected to high shock or vibration conditions
•
Mounting instructions
The DS7 solid-state soft start controller is easy to mount. It does
not require any special tools. To aid you with panel layout, refer to
the dimension drawings shown in
Figure 1
. Drill and tap holes per
mounting hole/slot locations as shown. To mount the unit, use all the
hardware specified in
Table 1
of this leaflet. Tighten to the specified
torque.

DANGER—HIGH VOLTAGE
HAZARDOUS VOLTAGE CAN CAUSE ELECTRIC SHOCK AND BURNS. TO
AVOID SHOCK HAZARD, DISCONNECT ALL POWER TO THE CONTROLLER,
MOTOR, OR OTHER CONTROL DEVICES BEFORE ANY WORK IS PERFORMED
ON THIS EQUIPMENT. FAILURE TO DO SO WILL RESULT IN PERSONAL
INJURY, DEATH, OR SUBSTANTIAL PROPERTY DAMAGE.
DO NOT APPLY A DISCONNECT DEVICE ON THE OUTPUT OF THE DS7
SOFT START CONTROLLER UNLESS A MEANS TO TURN OFF THE DEVICE
WHEN DISCONNECT SWITCH IS OPEN IS UTILIZED. OPENING THE
DISCONNECT WHILE THE SOFT START CONTROLLER IS OPERATING MAY
CAUSE A MALFUNCTION. CLOSING THE DISCONNECT SWITCH WHILE THE
SOFT START CONTROLLER IS OPERATING WILL RESULT IN POTENTIAL
EQUIPMENT DAMAGE AND PERSONNEL HAZARD.
