CONNECTING THE BATTERIES
The DC lift comes standard with two battery trays and
plastic battery boxes as well as the wiring kit to connect
them to the lift’s control panel.
The two 12-Volt batteries connect together in series to
create a 24-Volt system. It is important that the two deep-
cycle batteries are connected to the cables leading from the
electrical connection/circuit breaker panel exactly as shown
in Fig. 7 below. This 24-Volt system will reduce the
amperage draw on the batteries, and maximize battery life.
CHARGING THE BATTERIES
In order to achieve peak lift performance and maximum
battery life, the batteries must be properly charged and
maintained. If batteries are run down or faulty, the lift
system will either move very slowly or not at all.
Fig. 7 - 24 Volt System
All battery and motor connections must be corrosion free
and tight. If not maintained properly, excessive heat will
be generated which can melt the connections.
WARNING
Batteries that are improperly connected can cause
damage to the lift system, the batteries, and a potential
explosion.
WARNING
SELECTING THE BATTERIES
FOR 24-VOLT DC MODELS
Batteries are not
included with the lift
system. The
recommended batteries
(Fig. 6) are two 12-Volt,
deep-cycle, Group 27
(case size), with 600 cold
cranking amps and stud
post terminals with wing
nuts (lead top posts). An
Interstate SRM-27 meets
this criteria.

Boxes & Trays
(Note how cabling
from drive train
control panel is
neatly stowed and
completely
contained within the
battery boxes.)
Keep the cables from the connection panel inside the
battery boxes by running them through the first box, and
then into the second. The white battery interconnect
wire should also be contained within the boxes.
120 VOLT AC WARNING
For the AC
power
connection
please
contact a
licensed
electrical
contractor
to ensure
a safe
connection.
You must have
120v/20amp service to the connection on VSD drive train.
CHECK THE FOLLOWING TO ENSURE PROPER
OPERATION OF THE ELECTRIC MOTOR DRIVE...
Electrical System:
1. Power wires to the batteries & motor are properly
connected, corrosion free & tight.
2. Batteries are fully charged. When tested a 12 volt
battery will have between 12.7 and 13.8 volts.
3. Limit Switch is connected to 13-in. plug.
4. Wired Remote/Key Switch is connected to 10-in. plug.
5. Wireless Receiver (optional) is connected to 7-in. plug.
Important:
• Test the upper & lower limit switches before
initial use and seasonally to ensure the drive motor shuts
off automatically before coming to a hard stop. Test by
approaching the upper & lower cradle positions cautiously
with quick on/off triggers of the remote.
• If any portion of the electrical system is submerged,
please refer to the owner’s manual for corrective action.
Cable Note:
Ensure that cradle travels freely to the
bottom of the lift and keeps tension on lifting cable at all
times.
