System Power Requirement Calculation - D Series Units
WARNING! Calculate all power requirements, as stated below, before hooking up power. OTHERWISE,
DEATH OR SEVERE INJURY AND DAMAGE TO EQUIPMENT AND/OR THE CIRCUIT
COULD OCCUR.
Power requirements for the D4 System (unit, hoses and guns) must be calculated before hooking up power, to verify
that the hoses and guns do not exceed the power rating for the D Series unit. Personnel injury, as well as serious
equipment damage, can result from overloading the system.
This calculation will depend on the following two factors:
• The wattage for any hose/gun pair
• The total wattage for all hoses and guns
Perform the system power requirement calculation for the D Series unit as follows, referring to Table 1, below:
Table 1. Maximum Allowable Wattage for the D Series Unit
Line Description
Maximum
Wattage (W)
1 Total for hose/gun 1 pair 1800
2 Total for hose/gun 2 pair 1800
3 Total for hose/gun 3 pair 1400
4 Total for hose/gun 4 pair 1400
5 Total for all hoses and guns 8400
1. Add the power requirements of hose #1 and gun #1. Compare this value to the maximum wattage given
in Line 1 of Table 1.
2. Add the power requirements of hose #2 and gun #2. Compare this value to the maximum wattage given
in Line 2 of Table 1.
3. Add the power requirements of hose #3 and gun #3. Compare this value to the maximum wattage given
in Line 3 of Table 1.
4. Add the power requirements of hose #4 and gun #4. Compare this value to the maximum wattage given
in Line 4 of Table 1.
5. Add the power requirements of all hoses and all guns. Compare this value to the maximum wattage for all
hoses and guns given in Line 5 of Table 1.
6. If any of the power requirements calculated in steps 1-5 exceed any of the maximum allowable wattages
given in Table 1, the hose length or gun configuration must be changed, to reduce all power requirements
to below maximum-allowable wattages.
If each of the power requirements calculated in steps 1-5 is below the maximum allowable wattages given
in Table 1, the system power requirement is within allowable limits.
