9.0 - RATING PLATE DATA

The rating plate data (see example provided here) includes the following:
• Manufacturer's name/logo and address (possible distributor name/logo)
• Mod.: = device name/model followed
by the connection diameter
• P. max = Maximum pressure at which product operation is guaranteed
• PS = Allowable maximum pressure
• IP.... = Protection rating
• 230V.... = Power supply voltage, frequency (if Vac), followed by the electrical absorption
Example of electrical absorption indication: 55/16 VA indicates 55 VA at start, 16 VA at steady state
• TS = Temperature range within which product operation is guaranteed
• = In compliance with ATEX followed by the protection mode
(complete protection mode indicated on coil and CPI switch)
• = Compliance with PED directive followed by the no. of the Notified Body
• year = Year of manufacture
• Lot = Product serial number (see explanation below)
• U1804 = Lot issued in 2018 in the 4
• 2185 = progressive job order number for the indicated year
• 00001 = progressive number referring to the quantity of the lot
