2.5 Electrical Connection
The user / owner must provide the main power supply hardware (cable, conductor bar, fuses, disconnect
switch, etc.).
m
CAUTION: Make sure that the power supply voltage is the same as that shown on hoist serial
plate / nameplate.
m
CAUTION: Make sure that fuses and other current overload devices are in place to protect the
power supply.
m
CAUTION: Make sure that power cable or conductors have sufficient capacity to maintain the
hoist supply voltage by ±5 percent of nominal voltage under all operating conditions. Poor
voltage regulation may cause motor overheating or sluggishness, and chattering / inoperative
motor brake(s) and controls.
m
CAUTION: Do not use power supply cables with solid conductors.
m
CAUTION: Check the device cover is properly installed.
m
CAUTION: High voltages are present in this device. Switch the power off and after the display
turns off, wait 5 minutes before opening the cover.
m
CAUTION: Insulation resistance test with a megger multimeter requires special precautions.
m
CAUTION: Do not make any measurements in side the device when it is connected to the main
supply.
m
CAUTION: Do not touch the components on the circuit boards. Electrostatic discharge may
cause damage or destroy the IC-circuits.
m
CAUTION: Check all ventilation holes are clear and unobstructed.
m
CAUTION: Check that hot air coming from the brake resistors does not cause any danger.
m
CAUTION: It is forbidden to use radiophones or portable phones near this device with the
doors open.
m
CAUTION: Drive is not intended to be used in a low-voltage public network, which supplies
domestic premises. Radio frequency interference is expected if used in such a network.
