1: Receive and
Accept the Controller
Receive and Accept the Shipment
The
Reliance
r
DC2 V
LS
Controller
(herein referred to as controller)
has been designed, manufactured and thoroughly tested to provide
many years of reliable service. The shipping container in which you
received your controller has been specifically designed to protect it
during transportation and handling.
Reliance terms of sales, in all instances, are F
.O
.B. point of origin. It is
your responsibility to thoroughly inspect the equipment before
accepting shipment from the transportation company
.
If any of the items called for on the bill of lading or express receipt are
damaged or are not included,
do not
accept the shipment until the
freight or express agent makes an appropriate notation on your freight
bill or express receipt.
If any concealed loss or damage is discovered later
, notify your freight
or express agent within 15 days of receipt and request that he make an
inspection of the shipment. K
eep the entire shipment intact in its
original shipping container
.
The consignee is responsible for making claim against the Carrier for
any shortage or damage occurring in transit. Claims for loss or damage
in shipment must not be deducted from the Reliance Electric invoice,
nor should payment of the Reliance invoice be withheld while awaiting
adjustment of such claims since the carrier guarantees safe delivery
.
If considerable damage has been incurred and the situation is urgent,
contact the nearest Reliance Electric Sales Office for assistance. T
o find
the nearest sales office, call tollfree 18002454501.
Store the Controller until Installation
After
receipt inspection, repack the controller in its shipping container
until installation. If a period of storage is expected, store in the original
shipping container with its internal packing.
T
o ensure satisfactory drive operation at startup and to maintain
warranty coverage, store the equipment:
D
In its original shipping container in a clean, dry
, safe place.
D
In an ambient temperature that does not exceed 65
_
C (149
_
F) or go
below -30
_

File a Return Request
1. To
return equipment, send a written request to Reliance Electric
sales/service within ten days of receipt.
2.
Do not return equipment without a numbered authorization form
(ERA form) from Reliance Electric.
3.
Reliance Electric reserves the right to inspect the equipment on site
to verify any claims.

2: Introduction to the Controller
Controller Configurations
The
controller converts singlephase AC line power to adjustable D
C
power for either speed or torque control of D
C motors rated 1/4
through 2 HP
. The controller is specifically performance matched to
Reliance D
C Motors to provide a compact controller/motor package. It
will operate all Reliance 1/4 through 2 HP permanent magnet or wound
field D
C motors with compatible armature and field voltages.
The controller is available in a wide array of applicationspecific
configurations, in flat plate chassis or open chassis designs as well as
NEMA 12 or NEMA 4/4X/12 enclosure designs. T
ables 21 through
T
able 23 list available configurations.
Note
: Oiltight and dusttight conduit hole plugs (part 197308A) are
standard on DC2 NEMA 12K designs. Conduit hubs are not supplied.
Note
: W
ater
tight conduit hubs are standard on DC2 NEMA 4/4X/12
designs. Additional conduit hubs for NEMA 12 or NEMA 4/4X/12
designs can be ordered by referencing Reliance P
art Number
6088262A.
Note
: Models DC295 and DC297 feature a special 10turn speed
potentiometer
. Reference Reliance part number 60059414SFX for
replacement.
Note
: When the RE020 D
C T
achometer is used, a controller isolation
transformer must be used. See Install a Disconnect in Section 3 of this
instruction manual for complete instructions.

D
Selector switch has detent feature which requires release of
pressure on the switch when passing from forward to reverse. When
combined with the dynamic braking action, this feature minimizes
the possibility of plug reversing the motor
.

Conduit hubs for water
tight connection are provided at the conduit
entrance and a means to mount these hubs external of the
equipment cavity
. The Reliance DC2 controller has passed the UL
hosedown test to verify the washdown integrity of the controller
.
(1) When applying DC2 drives to power distribution systems with a KVA capacity in excess
of the maximum recommended KVA capacity, an isolation transformer or line reactor of
similar impedance is required.
(2) Assumes a transformer impedance of 5%.

Install the Drive
Review
all installation and wiring instructions thoroughly before
proceeding. Throughout the installation and wiring procedures, use
Figure 31 or Figure 31A to locate adjustment potentiometers, terminal
boards, special selector jumpers and pins. Wiring diagrams are given
in Figures 51, 51A
, 52 and 53.
Install the Controller
1. Remove
the controller cover and inspect for any physical damage.
Report any shipping damage to the carrier
.
2.
Locate the controller where it will have the unrestricted ventilation
area as indicated in Figures 32A and B. F
or the heatsink versions
(all models except the DC2 Series 50 product), allow for unrestricted
air flow over the rear cooling fins and sides. Allow at least 4" above
the controller
.
F
or the flat plate chassis design controller (DC2 Series 50) allow 1"
around the controller for service access. Also note that an 18" by
18" metal plate is required to meet the 1 HP @ 115 V
AC and 2 HP
@ 230 V
AC. An optional heatsink, model # HS150, is avaiable for
tighter areas (refer to Figure 3.2C).
3.
Make sure that ambient temperatures in the controller area are
within 0

C and 40
_
C (32

4.
Route power and control/signal wiring through separate conduit
openings provided in the bottom of the enclosed controller
. The
area above the controller must be kept clear of live electrical circuits
to avoid accidental contact. (See Figures 32A and B.)
5.
Mount the controller in a vertical, upright position. Mount the flat
plate chassis design with the ground lug located on the bottom right
side. See Figure 32 for dimension and mounting details.
6.
Seal the unused conduit entries of the NEMA 12 enclosed controller
,
using the supplied plug (part 197308A) to retain the NEMA 12
enclosure rating. Conduit connections should be made with
