3 Installation
3.1 Installation Site Checklist
3.1.1 Planning the Installation Site
Select the best possible operation site by considering
the following (see details on the following pages, and in
the
Design Guide
):
•
Ambient operating temperature
•
Installation method
•
Cooling
•
Position of the unit
•
Cable routing
•
Voltage and current supply from power source
•
Current rating within range
•
Fuse ratings if not using built-in fuses
3.2 Equipment Pre-Installation Checklist
•
Before unpacking the adjustable frequency drive,
examine the packaging for signs of damage. If
the unit is damaged, refuse delivery and
immediately contact the shipping company to
claim the damage.
•
Before unpacking the adjustable frequency drive,
locate it as close as possible to the final instal-
lation site
•
Compare the model number on the nameplate to
what was ordered to verify the proper equipment
•
Ensure each of the following are rated for the
same voltage:
•
Line power
•
Adjustable frequency drive
•
Motor
•
Ensure the output current rating is equal to or
greater than the motor full load current for peak
motor performance.
•
Motor size and adjustable frequency
drive power must match for proper
overload protection.
•
If adjustable frequency drive rating is
less than that of the motor, full motor
output is impossible.
3.3 Mechanical Installation
3.3.1 Cooling and Airflow
Cooling
Cooling can be obtained in different ways, by using the
cooling ducts in the bottom and the top of the unit, by
taking air in and out the back of the unit or by combining
the cooling possibilities.
Back cooling
The backchannel air can also be ventilated in and out the
back of a Rittal TS8 enclosure for frame size F18 LHD. This
offers a solution where the backchannel could take air
from outside the facility and return the heat losses outside
the facility thus reducing air-conditioning requirements.
NOTICE!
A door fan is required on the enclosure to remove the
heat losses not contained in the backchannel of the
drive and any additional losses generated from other
components installed inside the enclosure. The total
required air flow must be calculated so that the
appropriate fans can be selected. Some enclosure
manufacturers offer software for performing the
calculations (i.e., Rittal Therm software).
