Set No. 8 acc. to Table 15.
One set of spare parts per standard equipment set.
With Certificate of the USSR Register.
7. The spare parts set for the electrical equipment comprises parts and assemblies which can be used for the repairs to be carried out on the ship. The spares sets are packed in sturdy wooden cases adopted for long storage on the ship.
8. The spares set comprises the following parts and assemblies: braking disks for brakes — 1 set; brake coil—1 set; brake spring—1 set; moving and stationary contacts of all types—1—3 sets; springs for apparatuses of all types—1—4 sets; apparatus coils—1 per design version; fuses — 2 sets: rectifiers — 1 set; vitrified resistors—1 per design version; cam assembly—1 —11 per design version.
The list of spare parts supplied with the given equipment is included in the set of technical documentation.
Repeat the words after the teacher. Then read them by yourself paying attention to their Russian equivalents.

Read the sentences and point out numbers of those which deal with the topic “Procedure for Ordering Equipment and Spare Parts”.
1. Consult Tables listing electric drives of various applications. 2. Enable the control range to be extended to any limit that may be required in actual service. 3. Determine the power rating of servo motors from the formula. 4. Select a power drive equipment with the nearest power rating. 5. Connect a thyristor frequency converter to the 380 V supply mains through a 380/220 V transformer. 6. Make sure that the control properties of the drive indicated on the mechanical characteristics suit the operating conditions of the electric equipment set. 7. Provide for frequency increase or decrease at the predetermined rate. 8. Include the necessary information.
