2.5.1. Supply cables

The TC02 controller requires a 12 to 24 VAC supply. The valve actuators may be rated
between 24 VAC and 230 VAC. The controller does not supply actuators. Sizing and fuse
protection of 230 VAC supply cables depends on the total load and on local regulations.

2.5.2. Mounting the unit (if supplied without fan deck)

The controllers may be mounted in any orientation using metal Stand-offs, to suit the four
fixing holes, the minimum stand-off height is 5mm, 3 mm fixing screws are recommended.
Push over type plastic stand-offs may be used if it eases production.
The following points should be noted;
The controller should be freely accessible after mounting.
Adequate air circulation to dissipate heat generated during operation.
Easy access for service personnel.
Local installation regulations must be observed.
