Branch circuit protection must be provided in accordance with the Canadian Electrical Code and any additional
local codes.
9.2.3 Compliance with Peripheral devices
Use the UL listed fuses at connecting to power supply.
Short circuit test is performed under the condition of the power supply short-circuit currents in below.
These interrupting capacities and fuse rating currents depend on the applicable motor capacities.

Suitable for use on a circuit capable of delivering not more than___X___rms symmetrical kilo Amperes,___Y___Volts
maximum, when protected by___Z1___with a maximum rating of___Z2___.
(1) Input withstand rating is that for which the product has been designed thermally. Installation on a supply greater than
this level will require additional inductance to satisfy this level.
(2) Output interrupt rating relies on Integral solid state short circuit protection. This does not provide branch circuit
protection. Branch circuit protection must be provided in accordance with the National Electrical Code and any
additional local codes. This is dependant on the type of installation.
9.2.4 Motor thermal protection
Selects the electronic thermal protection characteristics that fit with the ratings and characteristics of the motor.
(Refer to section 3.5)
In case of multi motor operation with one inverter, thermal relay should be connected to each motor.
