Electrical Installation
Precautions
Before starting work, make sure that the safety instructions in the chapter
(page 3) have been read and understood.
DANGER: Electrical Hazard
Before starting work on the unit, make sure that the unit and the control panel are isolated
from the power supply and cannot be energized. This applies to the control circuit as well.
DANGER: Electrical Hazard
All electrical equipment must be grounded (earthed). Test the ground (earth) lead to
verify that it is connected correctly. Frequently inspect electrical systems to ensure that the
path to ground is continuous.
WARNING: Electrical Hazard
Risk of electrical shock or burn. A certified electrician must supervise all electrical work.
Comply with all local codes and regulations.
WARNING: Electrical Hazard
There is a risk of electrical shock or explosion if the electrical connections are not correctly
carried out, or if there is fault or damage on the product. Visually inspect equipment for
damaged cables, cracked casings or other signs of damage. Make sure that electrical
connections have been correctly made.
CAUTION: Electrical Hazard
Prevent cables from becoming sharply bent or damaged.
Requirements
These requirements apply for electrical installation:
• The mains voltage and frequency must agree with the specifications for the product.
• Circuit breakers must be installed between the main voltage line and this unit.
• All fuses and circuit breakers must have the proper rating, and comply with local
regulations.
• The cables must be in accordance with the local rules and regulations.
• If the power cable is jerked loose, then the ground (earth) conductor must be the last
conductor to come loose from its terminal. Make sure that the ground (earth)
conductor is longer than the phase conductors at both ends of the cable.
Requirements on incoming power supply
• The maximum permissible short circuit current at the SRC 311 power terminals as
defined in IEC60439-1 is 100 kA.
• Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the Canadian electrical
code, PART I and NEC.
