(1) Coolant temperature must be above the dew point to prevent condensation. If the water temperature is below the dew point, the appropriate water flow rate control is needed. Consult Rockwell

Automation.

(2) WEG25 = good quality or distilled water/ethylene glycol 25% by volume. An approved inhibited, silicate-free ethylene glycol is Ucartherm, a product of Dow Chemical Company.

ATTENTION: Ethylene glycol solutions must be inhibited and silicate-free. Use
of uninhibited and silicate-containing solutions can damage the cooling
system.

Condition

Specification

Electronic Motor Overload Protection:

Provides class 10 motor overload protection according to NEC article 430.
Does not provide speed sensitive overload protection, thermal memory
retention and motor over-temperature sensing according to NEC article
430.126 (A) (2). If such protection is needed in the end-use product, it
must be provided by additional means.
