1. IMPORTANT SAFEGUARDS
ELECTRIC SHOCK HAZARD: Read and understand all instructions before
installing, servicing or operating this controller. Failure to do so could
result in equipment or property damage as well as personal injury and
even death.
HIGH VOLTAGE is used in the operation of this equipment. DEATH ON
CONTACT may result if personnel fail to observe safety precautions.
Learn the areas containing high-voltage connections when installing or
operating this equipment.
Be careful not to contact high-voltage connections when installing or
operating this equipment. Before working inside the equipment, turn
power off and ground all points of high voltage potential before touch-
ing.
ELECTRIC SHOCK HAZARD. Any installation involving control equip-
ment must be performed by a qualified person and must be effectively
grounded in accordance with the National Electrical Code to eliminate
shock hazard.
The Owner/Installer must provide all necessary safety and protection
devices and follow all current electrical wiring standards and regula-
tions. Failure to do so may compromise the integrity of the controller
and/or cause product failure resulting in a safety risk to operational
service and personnel.
This controller utilizes a heat sink which is designed to cool the unit
during operation. Under no circumstance should air flow around the
controller be compromised in any way. Failure to do so may result in the
overheating of the controller, product failure, product temperatures and
even fire.
During continuous operation, the heat sink can reach a very high tem-
peratures, and keeps a high temperature even after the unit is turned
off due to its high thermal inertia.
Higher voltages may be present. DO NOT work on the power section
without first disconnecting electrical power to the panel. Failure to do
so could result in serious injury or death.
2. INSTALLATION - MECHANICAL
To ensure proper performance, maximum safety and reliability, it is essential to install
the unit correctly. This includes proper mounting, spacing, hardware and wiring. See
below:
1. Maximum surrounding air temperature is 40°C in “Open Type Equipment” which
is suitable for use in pollution degree 2.
2. Install the unit vertically (max 10° inclination from vertical axis).
3. Spacing:
–Min. vertical distance between unit and panel wall: 3.9” (100 mm)
–Min. horizontal distance between unit and panel wall: 0.79” (20 mm)
–Min. vertical distance between adjacent power control units: 11.81” (300 mm)
–Min. horizontal distance between adjacent power control units: 0.79” (20 mm)
