Adjustments:
Output voltage is factory set to provide sufficient power to the motor to maintain a +5° to 10°C
differential above ambient temperature which is suitable for most applications. This adjustment can be used to trim
the control as required for each application.
Fusing:
Two fuses protect the MWH.
Transient Protection:
An RC snubber circuit across the SCR protects it from rapid rate of change in the system
voltage. A metal oxide varistor (MOV) protects the unit against voltage spikes on the line.
1.4 Receiving and Unpacking
Unpacking -
Carefully unpack the unit from the shipping carton and inspect it for shipping damages. Immediately
report any damages to the carrier.
Mounting -
Select mounting location and make sure ambient temperature does not exceed operating range limits
given in specifications. Allow for sufficient clearance on all sides of the unit.
